It plays an important role in the coal selection process, mainly by separating coal and impurities through centrifugal force, improving coal quality, and reducing transportation costs. Centrifuge is a commonly used solid-liquid separation equipment, mainly composed of multiple components such as electric motor, reducer, centrifugal drum, balance device, etc. It has the characteristics of simple structure and easy operation. ‌

Working principle
The working principle of the centrifuge in the coal preparation plant is to use an electric motor to drive the centrifuge basket to rotate at high speed, generating centrifugal force. Under the action of centrifugal force, coal and water move towards the inner and outer sides of the centrifugal cylinder, respectively. Water flows out through the holes in the centrifuge tube, while coal is left on the surface of the centrifuge tube by centrifugal force due to its larger particles. Finally, coal is collected through the action of a scraper or airflow to complete the coal selection process.

Advantages and application scope
The advantages of centrifuges in coal preparation plants lie in their high efficiency, ease of operation, safety, and reliability. It can process a large amount of coal in a short period of time, improving coal preparation efficiency; Easy to operate, easy to maintain, can run continuously for 24 hours, ensuring safe and stable production. In addition, the centrifuge in the coal preparation plant has a small footprint and can be flexibly arranged in various scenarios. It is not only suitable for coal preparation plants, but also widely used in industrial fields such as coal washing and coal-fired power plants, helping to achieve clean and efficient utilization of coal and improve energy efficiency.
