Vertical type centrifugal dewatering machine for coal slurry and minerals
Introduction of Centrifugal Dewatering Machine
This series centrifugal machine is mainly used for sizes of 0~25mm clean coal and coal dehydration, max feed size should be less than 25mm.
Main features:
High centrifugal strength, low moisture content, easy operation, stable performance, low noise, long working lifespan.
We adopts advanced technology, new material, which increases the working life and reduces the change times for easy wear parts of the machine.
Working principle of Centrifugal Dewatering Machine
Ore pulp is delivered by feeding pulp distributor through two location to the inner wall of drum, while the drum is spinning at high speed.
Ore pulp spins along with the drum. Under the action of centrifugal force, the heavier mineral deposits on inner wall and spins along with the drum. The lighter mineral grains spin at a speed different to drum. During the process of spin, lighter mineral grains will be discharged out of the drum. After 3 minutes, the pulp distributor will turn away from normal position and stop feeding ore pulp. After finishing discharging the tailings, discharging pulp distributor will turn away from normal position and be prepared to receive the concentrate. High pressure flushing water valve will switch on automatically and wash the concentrate down off the inner wall. Then the valve will switch off automatically.
After discharging all the concentrate, discharging and feeding pulp distributor will return to their normal positions and start another separation circulation.
