Operating principle

The mixture of solid and liquid is distributed uniformly&quickly in centrifuge drum by feeding tube and distributing evenly through the distributing disk. acting on the centrifugal position. Liquid-solid mixed fluid intercept the solid phase through the fitter to filter out the liquid phase. Centrifuge continues to feed until full. Then stop. Solid cake is rinsed and purified when the process requires. And the rinsing liquid is filtered out meanwhile.  Centrifuge further filter until the separation requirements are met.

 

 

 

Control Process

The operation of centrifuge is controlled by PLC. The system runs automatically according to the preset program. Different centrifuges have corresponding operating parameters or range of adjustment.

In order to meet the requirements of separation. appropriate operation parameters are set for specific conditions

in debugging and subsequent operation. The control system can automatically repair or protect the overload in the actual operation.

Automatic control system controls centrifuge mainframe, hydraulic system, pneumatic system, N2 protection system,and pump, valve, material conveying system related with centrifuge, etc.
