Working principle

    The solid and liquid mixture will be fed into the centrifuge drum via feed pipe and distributed evenly all over the inner wall of the drum, at where the solid phase will be retained by filter disk under effect of centrifuge field while liquid phase discharged out of the filtration process. The feeding process will keep going on until the centrifuge drum is fully charged. Filtering cake will be rinsed and purified as necessary and rinsing water will be discharged meanwhile. Then, there comes a further dehydration process till effective separation is achieved. In process of full or moderate speed running, the scrapper will peel off most of the filtering cake and one entire working cycle completed. 
GKH’s operation is based on siphon principle, designed with filtering power, resulting in lower water content of filtering cake.
 

Control process
Centrifuge operation is PLC controlled, where the system will run preset program automatically with operation parameters or their adjustment range varying for different models/types of unit. Appropriate operation parameters will be defined and set for specific working condition based on results of testing/commissioning and subsequent operation in the aim to achieve effective separation. The control system will fix or protect from overload in process of operation automatically. 
The automatic control system controls main engine, hydraulic system, pneumatic system, N2 protection system, valves as well as pumps, valves and material conveyance system etc. relating to the centrifuge.
