Centrifugal ore separator
Advantages:
Reliable performance; large capacity; small area required; high automation; particularly suitable for fine slurry
Introduction:
Centrifugal concentrator is known as centrifuge or centrifugal chute. Strong centrifugal force produced by high speed spin strengthens the process of gravity separation and effectively recover the ultrafine ore particles. Nowadays, centrifugal concentrator is widely used for the recovery of gold, tungsten, lead, manganese, iron, etc.
Working principle:
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.
Characteristics:
1. very effective for the process of ultrafine ore slime, The recovery rate of 37-39 micron is over 90%.
2. Under the action of centrifugal force, the process of gravity separation is strengthened and the separation time is much shortened. Therefore, the capacity of centrifugal concentrator is much bigger.
3. Small land coverage and high automation
