What is the operation process of coal centrifuge

A coal centrifuge is a machine that separates coal particles based on their size and density using centrifugal force. The operation of a coal centrifuge involves the following steps:

Feed preparation

The raw coal is crushed and screened to remove impurities and large particles before it is fed into the centrifuge.

Clean Coal Centrifuge


The prepared coal is loaded into the feed hopper of the centrifuge.


The centrifuge rotates at high speed, causing the denser coal particles to move towards the outer edge of the drum, while the lighter particles move towards the center.


The separated coal particles are discharged from the centrifuge through separate outlets for different densities.

Slime Centrifuge


After the coal is separated, the centrifuge is cleaned to remove any remaining coal particles and debris.


Regular maintenance of the centrifuge, including cleaning, lubrication, and inspection, is necessary to ensure its optimal performance and longevity.

Overall, the coal centrifuge operation is a continuous process that requires careful monitoring and maintenance to ensure efficient separation of coal particles.
