Therefore, building materials and machinery for construction machinery products have been well developed pre-market bedding.

concrete molding machine

Construction machinery and equipment in everyday, common mechanical equipment: tower cranes, aerial work platforms, lifts, lifting equipment, lifting machine, truck, machine, bar straightening cutting machines, motors, crushers, concrete mixer, concrete pump, concrete batching machine, concrete jet, vibrators and vibrator, etc.,Concrete mixing plants the construction of urban and rural construction and machinery and equipment used. Innovation, concrete molding machine in the domestic market share of Wenduo first; import means of information, close docking worldwide 106 countries and regions, more than 7,000 customers, the rapid growth of peaks mechanical equipment manufacturing market in Quanzhou a shining pearl.
Body mass has more than 500 billion yuan, Quanzhou, a veritable specialty equipment manufacturing industry cluster. "Road construction machinery, brick machinery production, technical level are the first in the province." Late last year, Quanzhou Economic and Trade Commission to conduct a survey equipment manufacturing industry, the research group, responsible person, South Road Machine's top dry type sand making technology, batch mixing plant machinery peaks waste disposal equipment to become the industry leader. Sustained technological innovation and management innovation, boosting these two equipment manufacturing enterprises in Quanzhou called standard-bearer.

Concrete machinery produce different energy and productivity

Because concrete machinery, even if the same company in the same model, the same specifications of the product, just pumping concrete cylinder piston installation differences, it will make running resistance and productivity changes, will produce different energy and productivity, Precast concrete plant common sense, not to mention the various enterprises of different product positioning is not, as in the choice of parameters, the size of the pumping pressure distribution, configuration varies, cost is not the same, some specializing in long arm, some specializing in high- lift distance, some specializing in high-performance, some specializing in high reliability, how more than a few products only in the models, specifications of the choice of the enterprise is difficult to unity, why must we go to the strengths of their products than other people's so-called "short board" mean? So to be truly scientific and rational, there must be a professional appraisal team, concrete mixer machine on the content of the contest when possible. Of course, within the enterprise through pilot testing to compare the advantages and disadvantages of each enterprise products to improve their level is possible, normal. However, in a test of public occasions business model in the world market is also extremely rare. I hope the industry exclusive commercial activities organized similar events do not happen again.

The delivery of quality concrete

However, the reality of the past 10 years shows that the concrete mixer truck is not effective implementation of national standards most of construction machinery, concrete conveying quality and safety of the transportation process are not properly guaranteed. stationary concrete batching plant produce mixer truck, concrete is not able to guarantee deliveries of segregation, whether generated or excessive bleeding detection and stir yet defined, concrete projects can guarantee the quality, but also the lack of final inspection. The durability of concrete indicators are able to achieve it is worrying.
Concrete mixing plants than two hundred thousand units mixer truck in the safe operation aspects, more serious. Driving stability greatly affected, because the increase in the total mass of the heavy travel speed is constant, a geometric inertia force multiplier, making the car's steering and braking force seriously out of control, urban construction vehicles in traffic accidents , mixer accounted for first place, many drivers become taken advantage of this equipment and the victim. Root cause lies in the so-called manufacturers to meet the user's requirements, and seek maximum sales resulting design is not standardized.

Concrete machinery industry Adverse events

Therefore, concrete machinery industry Adverse events are still controllable and not past the bridge, and to those who can catch, effort and enterprise of the entrepreneur's excess funds, Precast concrete plant transformed into basic components up, if the engine, transmission parts , hydraulic parts, controllers, etc. contribute to and hope that some of the more high-tech mergers and acquisitions base parts enterprises, so that talent is not cause for genuine dedication to the respect by the industry, or ready mix concrete plant, also foreign parts assembly plant, you then also for foreigners thinking ahead advertise products for foreigners to reap high profits, have to let outsiders look down on humble self, it should not be that we pursue and declared dyed purposes.

Concrete mixer truck is an important transport machinery construction work

Concrete mixing plants is an important transportation construction engineering machinery, the current is still no uniform international Terminology and commercial specifications. Building construction machinery and equipment according to the first sub-technical mixer truck new working group is mainly responsible for drafting the new proposal "Building construction machinery and equipment concrete mixer truck - Part 1: Terminology and commercial specifications", will develop mixer truck Terminology and commercial specifications weaken trade barriers to promote international trade.

Concrete compressive strength test

① In the same rubber powder particle size in the case of concrete slump, apparent density, 28d compressive strength Stationary conacrete plant with the increase of rubber powder content  decreased, while the gas content with the rubber powder content increases;
② In the case of the same rubber concrete mixer machine, the slump of  the concrete mixture, apparent density, and coagulation 28d compressive strength of soil with rubber powder and reduce the particle size decreases, the gas content increases with decreasing particle size

Rubber powder production of concrete

Rubber powder concrete produced for the efficient utilization of resources rubber powder provides an important way. Stabilized Soil Mixing Plant that the waste tires into rubber powder into concrete, not only can improve the brittleness of ordinary concrete to improve the toughness of concrete, ductility, crack resistance, but also has good heat insulation, sound insulation, shock absorption performance. Therefore, the rubber powder concrete has broad space for development and application prospects. Rubber powder concrete as a new material, the current research is not the kind of material is very good. This study is different rubber powder particle size and concrete mix plant physical and mechanical properties studied to provide a basis for the practical application of engineering.

Concrete mixing process of rubber powder rough surface structure

Rubber powder has the role of air-entraining agents for rubber powder, rubber powder as dosage increases, the air content of concrete in varying degrees of increase, and were higher than the reference concrete containing gas
Volume. Precast concrete plant powder particles in the concrete mixing process, the rough surface of the rubber powder wrapped in a structure not only part of the water, but also a part of the air parcel, played a lead role in air, these air-stable presence in concrete. So rubber powder content, the more air entrainment is also greater. When the rubber powder content the same time, smaller particle size, rubber powder particle ready mix concrete plant part of the greater amount of space, the overall adsorption air is more, it also presents the gas content decreases with increasing particle size rubber powder big trend.

Coarse and fine aggregate and cement concrete density

This is because The apparent density of the rubber powder is smaller than the thickness of the concrete aggregate and cement density, the rubber powder by a Fixed proportion of mixed concrete, unit volume decreases the amount of other materials, thus reducing the mixed Concrete mixing plants of concrete, and the scope of the rubber powder content is not so apparent density of concrete Impact is limited. Rubber powder content in the same circumstances, exhibit an apparent density of the concrete with Rubber powder particle size decreases and decreasing trend, and the lower range is not great. For example: When the rubber Powder content of 3%, the three kinds of rubber powder particle ash apparent density of concrete were: 2386,2300,2372 kg/m3. This is because the unit mass of the rubber powder, the smaller the size, the volume occupied by the more Large, relatively reduced incorporation of the concrete stationary concrete batching plant other materials, so the case of the same dosage, The apparent density of the concrete is reduced with decrease of particle size. And because the dosage is small, the apparent density Much lower degree range.

The strength of the concrete produced lower

① rubber powder is an elastic material,Rubber powder particles is far lower than the strength of the other components of the concrete strength of the material. In the role of external forces,The deformation of rubber powder particles and other materials in concrete deformation produced inconsistent, solid concrete Reduced inter-bearing area, around the particles of the rubber powder gradually cracks eventually destroy, and rubber Stabilized Soil Mixing Plant, the more easily damaged. ② special nature rubber powder materials, it is difficult to determine with Cement interface well together, so that inside the concrete to produce a large number of weak boundary Surface, and the weak interface with the increase of rubber powder dosage increase. Therefore, the thin rubber powder concrete Under the effect of weak interface reduced ability to resist external forces, so the compressive strength decreases. ③ Through analysis we Know, rubber powder concrete with air-entraining effect, can produce large amounts of concrete and stable bubbles inside, stationary concrete batching plant by reducing the sectional area of the concrete, but also resulted in a reduced strength of the concrete produced Low. Rubber powder content in the same circumstances, rubber powder 28d compressive strength of concrete with rubber exhibit Powder particle size decreases and the decrease. This is because the specific surface area of rubber powder rubber powder with particle size The decrease of, resulting in a weak interface to increase inside the concrete, the concrete compressive strength With the decrease of rubber powder particle size decreases.

The compressive strength of concrete

The slump of concrete with rubber powder content is increased. Rubber powder content in a certain situation Case the slump of concrete with rubber powder particle size decreases and the decrease. rubber powder concrete air content with rubber powder content increases, the rubber powder content Under certain circumstances, the air content of concrete with rubber powder particle size decreases. Precast concrete plant density of the rubber powder with the concrete increases the rubber powder content is reduced and the rubber Powder, rubber powder content in certain conditions, the apparent density of the concrete with rubber powder particle size decreases Decreased. 28d compressive strength of concrete rubber powder, concrete mixer machine content increases with decreases in the rubber powder doped Under certain conditions, the amount of concrete compressive strength of rubber powder and reduce the particle size decreases.

Concrete pump or pump model selection

Concrete pump or pump model is selected according to its pumping capacity, and its pumping capacity generally based on the maximum displacement per unit time (m3 / h) and the maximum pumping distance (m) to represent. Precast concrete plant are generally in the product technical specifications have, in the choice of concrete pump or pump type and calculate the number of units, we need to use these data. But in the product specification given in these data are in some standard conditions (such as concrete slump 18 ~ 21cm pebbles) can be achieved under continuous pumping data, and maximum displacement and maximum pumping distance is not may be achieved simultaneously. When conditions are not the same standard conditions as described above, concrete mixer machine or pump the actual pumping capacity is bound to change. So in the actual construction of concrete pump or pump pumping capacity of less than actual technical specifications given in the data, during the construction organization design, according to the specific conditions to determine the actual concrete pump pumping capacity can be achieved.

Concrete pump should meet investment

Beyond the scope of the above should be based on the actual situation, choose different maximum pressure pumping concrete pressure pump.  concrete pump should be selected to meet the operational requirements of engineering concrete persons. Such as concrete slump, Concrete mixing plants coarse aggregate, gravel grading, concrete disabilities are low-intensity or high intensity. If the maximum size of coarse aggregate inconvenience control, selectable with good suction gate valve concrete pump; if the maximum size of coarse aggregate is strictly according to the standard supply, the choice of the general suction valve concrete pump . concrete pump should be selected according to the construction site power supply conditions. Where there is a system power supply, the capacity to meet the requirements, it should be to opt for electric pump, ready mix concrete plant be used in these pumps. tunnel construction, rail transport operations should be used in concrete pump track, trackless transport operations used tires mounted concrete pump. from construction operations near explosive gases, such as oil depots, chemical plants, the "gas" in tunnel construction workplace should be used in explosion-proof concrete pump.

Maximum pumping concrete pressure

With the development and improvement of building technology of concrete pouring increasingly high requirements. Stationary conacrete plant is the increasing amount of disposable concrete pouring, pouring concrete on the other hand is highly increasing. Therefore, in recent years our concrete pump technology developed rapidly. Its specifications are: theoretical maximum throughput of 30 m3 / h ~ 125 m3 / h variety of specifications, the largest concrete pumping pressure 3.1MPa ~ 20.5MPa variety of pressure pumps. Divided according to their running wheel tire and track-two; divided by butterfly valves, gate valves and valve three kinds; accordance with diesel driven power pumps and batch mixing plant, concrete pump driven by an electric motor is divided into non- Explosion-proof and explosion-proof type. Various pump has its own unique advantages.

Select concrete pump

(1) should be based on the construction organization design is based on selected concrete pump, concrete pump should be selected to meet the construction methods and quality of the project and work less. (2) the selected input Xue concrete should be technologically advanced, high reliability, good economy, high working efficiency. (3) concrete pump must be selected to meet the construction of the largest unit of time when pouring concrete requirements and maximum height
Degrees, the maximum horizontal distance requirements, there should be a certain technology and Concrete batching plant reserves, balanced production capacity of 1.2 to 1.5 times better. (4) the same site should not be using excessive number of units and a plurality of pump manufacturers, so as not to affect the normal use and large reserves of spare parts and repairs caused difficulties. (5) shall meet the requirements of special construction conditions. Concrete mixing plants no system power, tunnels and rail transport of explosive gases occasions. (6) should be considered corporate capital investment for the project and the future direction of development capacity and ability to reserves.

There are double rotor wheel type

There are double rotor wheel type, straight-tube type three rollers and belt slot type three. Stabilized Soil Mixing Plant type concrete pump, from the hopper, pump, squeeze the hose, vacuum system and power system components. Pump seals, pump body rotor-mounted two planetary roller, pump wall lined with rubber pads, inner plate with extruded hose. Planetary roller slewing drive power unit, rolled extruded hose, squeeze the tube inside the concrete pipes discharge. Vacuum system allows the pump body to maintain stationary concrete batching plant vacuum hose extrusion promote restitution immediately after rolling, and to accelerate concrete hopper suction hose squeezed inside. Extruded concrete pump displacement, depending on the radius of gyration of the rotor and rotary speed, squeezing the suction hose diameter and concrete volumetric efficiency.

Hydraulic concrete pump from the hopper

There are hydraulic and mechanical drive type. Hydraulic concrete pump from the hopper, hydraulic cylinder and piston, concrete tanks, dispensing valve, Y-shaped tube, washing equipment, Precast concrete plant and power systems and other components. The hydraulic system by the pressure pushes the piston reciprocating motion. When the suction piston backward, forward and backward through the Y-shaped tube when the concrete pressed into concrete cylinder pipes. After pumping concrete, or compressed air cleaning with high pressure water pump and pipes. Concrete pump piston displacement, depending on the number and diameter of the concrete cylinders, ready mix concrete plant velocity and concrete cylinder sucked volumetric efficiency. Diaphragm in the pump body, when the pump below the water through the diaphragm control valve withdrew tanks, the diaphragm subsidence, concrete hopper pressure to open the check valve into the pump; when the pump in the tank of water through the pump control valve withdraw When the diaphragm pressure water rises, closing check valve, pressed into the concrete drain pipes.

Piston can be divided into mechanical and hydraulic

Concrete mixing plants can be divided into its piston extrusion, pneumatic type three type is. Piston can be divided into mechanical and hydraulic, mechanical due to structural bulky, excessive noise, short life, energy consumption, the defendant has been gradually eliminated; hydraulic hydraulic and pressure can be divided into type (ie diaphragm type). Extruded concrete pump for pumping lightweight concrete, batch mixing plant pressure is small, so the pump short distance. Pneumatic conveying concrete formula with compressed air. Hydraulic diaphragm pump concrete from the hopper, pump, diaphragm control valves, pumps and water tanks and other components.

concrete mixer drum is mainly divided into

JZM series friction drum concrete mixer, Stationary conacrete plant type concrete mixer. Where concrete mixer drum Most characteristic is JZC series of concrete mixer drum-JZC350 diesel drum concrete mixer,JZC350 Diesel concrete mixer drum is an uncommon concrete mixer drum, which is also used to climb a Bucket loading concrete mixer drum, but JZC350 Diesel concrete mixer drum is generally used diesel engineering As concrete mixer drum, so JZC350 Diesel concrete mixer drum inconvenient places suitable for electricity Areas or countries, so JZC350 diesel drum concrete mixers suitable for export use, are all concrete mixing Machine, whether it is civilian-type concrete mixer drum, or engineering compulsory concrete mixer outlet so that the most suitable Used concrete mixer machine, and JZC350 Diesel concrete mixer drum is the only dual-purpose concrete mix can Mixing machine, that JZC350 Diesel concrete mixer drum work either electricity, you can also use diesel fuel work, which is JZC350 diesel drum concrete mixers most special places.

characteristics of the use of concrete mixers

Advantage: concrete mixer can mix plasticity, dry hard, mobility and lightweight aggregate concrete and mortar. Precast concrete plant the batching machine Combined, can be composed of small and medium sized mixing station. Widely used in highways, bridges, power plants, dams and other engineering and medium-sized precast plant Construction enterprises. Users can also customize with dump truck, dump truck, mixer truck use, but can also be modified according to the special requirements System to meet user needs. Engineering concrete mixer used for: Concrete mixers host not only used in the mix Soil engineering, but also for ceramics and refractories manufacturing. Can be used alone, or as a mixing station (F) supporting the main Machine. Plastic mixing various proportions of concrete, but also mixing various proportions ready mix concrete plant, lightweight aggregate concrete and Mortar, mortar, the construction works, roads, water, bridges, and a variety of Qin mold precast concrete production plant ideal machine Firearms.

Concrete mixer Precautions

Concrete mixing plants  for a period of time when work is needed after maintenance, in addition to routine maintenance work including Content, but also need to check and adjust brake clearance, such as the clutch inner and outer brake band wear off very to be replaced, adjust the concrete mix Mixing machine mixing blade and the blade clearance between the liner, the hopper and the discharge door and a flexible airtight condition, concrete mixer machine of a water distribution system algorithm normally. Concrete mixers Concrete mixers using chain drive need to check the chain pitch Elongation situation.

Concrete mixer drum

Bad cylinder wall, so to avoid the winter to ensure concrete mixer drum drum there is no water. Precast concrete plant easy to freeze,Concrete is also easy to solidification, solidification of concrete in the tube wall is not only difficult to clean, and if the cumulative number of words, will the coagulationSoil mixer's work have been affected. concrete mixer drum after the end of each work, be sure to clean up the water remaining inside the concrete, and To timely clean-up. under normal circumstances would snow in winter, if you can not be on the interior concrete mixer drum, then, stationary concrete batching plant to Mixer covered live, sunny promptly clean up after the snow above. Drum concrete mixer drum so simple protection methods Single, for your Blender longer serve you, fight to protect your mixer it!

Concrete and road equipment industry

"Construction Machinery in 2011 the market share of nearly 9000 million road machinery equipment assuming there are 500 million yuan annual output value of the international and domestic market demand attracted into commercial concrete and road equipment industry, Concrete mixing plants already mature brick many needs in this area.
Despite the current overall construction machinery market is not optimistic, but because of the popularity of China's urbanization trend is inevitable, the process of urbanization in the market demand for construction machinery, engineering machinery, and 10 years of golden period. In the valley, the construction machinery will usher bottomed.
Construction machinery is not a whim decision. Previously, the mechanical equipment of the wall a very good reputation among customers, many brick-making machines and concrete customers downstream customers concrete mixer machine. Therefore, building materials and machinery for construction machinery products have been well developed pre-market bedding.

new aerated concrete brick production line performance

Stabilized Soil Mixing Plant and application of the product is light weight, reducing the overall load of the building, it can significantly reduce construction costs. It can be widely used in load-bearing exterior walls, interior, non-load-bearing wall, the inner wall. Stability of the product is extremely low thermal expansion and contraction value, excellent stability. Compressive strength properties 3.1 of the product than the national standard 10MPa, reached 13.7 MPa. 3.2 Water resistance: batch mixing plant resistance of the product, which is owned by a company's unique patented technology, which can be controlled in softening coefficient from 0.76 to 0.93.  

Truck driving agitated mixing tube rotation

This problem only with the truck when traveling agitation mixing drum rotates, driven cylinder concrete, Stabilized Soil Mixing Plant centroid shift towards a situation to determine the direction, but also with truck driving state (turning radius, speed, vehicle centroid total offset, etc.) factors. This mainly refers to the safe speed to ensure that vehicles in turn with rollover phenomenon does not occur when speed. When driving straight side slope safety and batch mixing plant on the side, not specifically discussed here.
National truck driving the direction of rotation of the mixing tube is usually their eyes on a side road vehicles driving regulations to determine.

Concrete mixing tube led the flip

Vehicles belonging to urban transport type vehicles, most of its transport time to change directions, yield to pedestrians and vehicles traveling movements, not possible to do maximum speed. Concrete mixing plants, the truck is refitted by the chassis, the vehicle center of gravity than the center of gravity chassis before modification has significantly increased; while its transit led the concrete mixing drum, rotate it toward the center of gravity offset mixing drum rotation direction, thereby the axis of the mixing tube to the center of gravity in the vertical plane, so that affects the vehicle concrete mix plant, easy to roll when cornering, especially at high speeds, it will result in a higher rollover accident rate. Jicha Sharp, and are often the main cause truck overturned.

Concrete mixer truck itself high center of gravity

Based on the above understanding, their high center of gravity vehicles, driving traffic complexity, as a city truck that objective existence, in its use should pay close attention to the driving stability and prevent rollover. Manufacturers should not be highlighting its maximum speed when not possible consequent rollover accidents caused warnings to be effective.Precast concrete plant annotation within the chassis for the vehicle maximum speed maximum speed, does not explain the actual driving should comply with "technical conditions" states: "The agitation speeds, batch mixing plant shall not exceed 50km / h". Therefore, the manual should be fully expressed at high speed will bring high risk of rollover accidents.

The actual situation of the concrete mixer truck

Stationary conacrete plant for maintenance and repair of concrete mixer truck for transportation vehicles, in the maintenance and repair must comply with the Ministry of Communications Decree No. 13 of 1990, the Executive "periodic testing, mandatory maintenance, concrete mix plant, as appropriate," the maintenance and repair system . Under this premise, combined with the actual situation of the concrete mixer truck, good maintenance and repair.

Concrete tank rotation

In order to ensure sound and reliable drive, you should do the following maintenance work:
a. Universal rotation part is failure-prone area, should when greasing and regular checks of wear, and timely repair replacement. Team should spare cardan shaft assembly, in order to ensure the event of failure can resume work in a few minutes.
b. Ensure the hydraulic oil clean. Stabilized Soil Mixing Plant working environment, we must prevent sewage sediment entering the hydraulic system. Hydraulic oil according to the user manual require periodic replacement. Once the inspection found that the hydraulic oil mixed with water or sand, we should immediately stop cleaning hydraulic systems, replacement of hydraulic oil. c. Ensure the hydraulic oil cooling effect. To regularly clean hydraulic oil cooler, to avoid clogging the radiator is stationary concrete batching plant the radiator electric fan is functioning properly, prevent hydraulic oil temperature exceeded. Just be sure the hydraulic oil hydraulic parts cleaning, general fault much; But different manufacturers, the service life is not the same.

Concrete solidifies into lumps in a short time

Since concrete solidified into lumps in a short time, and the steel and paint has some corrosion, so the concrete tank after each use, wash and adhere to the concrete tank on the material inlet and outlet of the concrete is a daily maintenance must work seriously. Including:
a. Precast concrete plant before each filling inlet, so that when the inlet kept moist during charging;
b. At the same time charging comes to vehicle wash water tank filled with water;
c. After loading washing Inlet, near the mouth of the feed residue washed concrete;
d. To the site after unloading, rinse out the chute, and then added to the concrete tank cleaning water within 30-40 L; return the vehicle to keep the concrete tank forward slow rotation;
e. Remember to let go before the next charging within the concrete tank sewage;
f. Each day when the concrete tank and ready mix concrete plant out material around the mouth, to ensure non-stick cake with cement and concrete. These work for as long as one is not careful, it will give the future work of great trouble.

Mixing tube is concrete containers

Mixing device consists of mixing tube and auxiliary support components. Mixing tube is concrete containers, concrete along the blade rotating spiral direction, constantly upgrading and turning process by mixing and stirring. In the feeding and transport process, Concrete mixing plants is transferred, the concrete along the blade inward movement, the material, the mixing tube reversal, concrete discharged outward along the blade.
Stirring blades are the main components of the device, can cause damage or excessive wear uneven mixing concrete. In addition, if the angle of the blade design is unreasonable, but also to make concrete appear segregation.
Cleaning system's main role is to clean batch mixing plant, also sometimes used for transportation of dry material mixing drum. Cleaning system is also a cooling effect on the hydraulic system.
Fully enclosed device using rotary sealing technology, sealing the mixer's expected out to solve the traditional mixer water evaporation, mortar layered, concrete material spilled, traffic safety and other issues.

Mortar mixer for mixing different materials adjust the speed

Stationary conacrete plant throwing knives in the shaft with only one 11kw variable speed motor that can really break up the material for different things Adjust the speed when mixed material to protect the material is not destroyed, the role goes far beyond the small knife stirred tank wall. From a structural Considerations, equipped with a large knife and batch mixing plant effect far beyond the ordinary blender, even 300 days non-stop operation, power consumption is 79 200 degrees, with little effect of 324 000 degrees phase comparison, only one quarter.

Mortar mixer elongated mixing time

Precast concrete plant the uneven mixing, some manufacturers use elongated mixing time, mixing time increases, the material especially sand and vitrified micro-Beads will be destroyed the original particle size, while the mixer blade life will be shortened and the barrel wall, a further increase in mixing time was Expected to improve only concrete mix plant, must not absolute, because the mixer structure determines material mixing uniformity. Three kinds From this phenomenon, fixed on the mixing drum knife on several devices are basically not as means of little use, or even Long years of waste.

Mortar mixer apparatus used in the knife

Stationary conacrete plant in the mortar mixer device should first consider the blender knife work, materials and agglomerated materials (referring to things Material pre-state condensation), how many times can come across very few of the knife on the mixing tank, the theoretical material will be longing knife fight Scattered, in fact, be the material in the mixing knife hit does not exceed 50% of the material has not been hit knife, concrete mixer machine agglomerate or additive concentrate did not get along well dispersed; Then consider mixing drum mounted on the knife, mixing Distance between the blades must avoid rotation hit Flying distance is the mixing of the dead, knife and more appear spacing The more places, the more dead.

Stirring shaft compulsory mixer

Stabilized Soil Mixing Plant compulsory mixer with counter-rotating mixing blades, can stir the material in the ω-shaped cross-stirred tank was mutual Measures, the spiral movement reciprocating cycle to produce a strong three-dimensional mixing space, especially in the center of two mixing cycles Junction formed a strong vortex, weightless blend areas, so that the material in the compulsory mixer mixing blades and batch mixing plant, rub down, a short time to fully mix;
Compulsory mixer power consumption is low because the principle of the apparatus used for mixing instant loss, reducing the sliding resistance of the material with each other,Easy to damage the original state of the material, a short time you can get the macro homogeneous concrete, while planetary mixing and stirring no turboprop Have this advantage, they obviously on slightly higher energy consumption.

Forced mixer blades and mixing arm bolted

Compulsory mixer large aggregate of sports, can play the role of agitation, increased mixing capacity.Concrete mixing plants and the shaft bolted Access, maintenance of good performance, easy to replace; compulsory mixer blades bolted with mixing arm, and the arm has a long mixing Holes for easy adjustment of the gap blade and liner in close proximity to both ends of the ready mix concrete plant arm, respectively, having a side blade for scraping off the end of the The surface of the concrete.

Concrete mixing station equipment installation method of offset roller

Concrete mixing station equipment installation method of offset roller
If the conveyor is installed on several groups of self-aligning roller (roller or a flat groove roller), that is able to automatically correct tape deviation phenomenon. For example: Precast concrete plant and appear on one side of a small block roller friction, should make a stand along the side of the tape running direction forward, the other side Is relatively moved backward, then the tape will be moved toward the rear side of the resist roller moves, until return to the normal position. concrete mixing station equipment installation limit idlers France If the tape is always to the side of the deviation can be mounted on a rack laterality run limit edger; Thus, batch mixing plant allows the tape to force strong System reset, the other vertical roll can reduce run laterality tape tension, for the tape to the other side.

Concrete mixing station equipment calibration qualified

In order to ensure the quality of concrete mix, the Shanghai-Kunming passenger line Guizhou section of each section of concrete mixing station must follow company information required to set the screen monitoring system.  the Precast concrete plant passenger line Guizhou section of each section will need to install concrete mixing stations are mixing station management information system, according to the specified application and acceptance are not allowed to install and use.concrete mixer machine is completed, after passing all the equipment calibration submit concrete mixing station enabled applications for concrete mixing station to enable submission of copies in quadruplicate, the project materials submitted by the engineering department responsible for auditing the headquarters, while the command Ministry will organize relevant departments to carry out the preliminary acceptance mixing station after acceptance in accordance with the program submitted by the headquarters.
