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.
