concrete mixer truck discharge problem of uneven

Precast concrete plant the material issue is an important indicator of performance mixer, which directly affects the quality of the project. Transporting concrete, batch mixing plant speed should be controlled at 2 ~ 5r/min, and the total number of revolutions mixing tube at 300 rpm inside. If the long distance transport of concrete or slump is large, the material should be preceded by the fast rotation mixing drum 5 to 10 rpm, so that the concrete can stir inside, so the uniformity of the material will be greatly improved. If the way of concrete dehydration, water should be added to the site adjustments, and stir. Of course, this situation should be avoided, since this would not be the quality control of concrete. Some users do not pay attention when using speed control during transport, excessive fuel consumption will increase, too small will result in concrete segregation. Should therefore be strictly required to control the speed of mixing drum, in order to facilitate and improve efficiency.
