How does a cuttings dryer work?

The working principle of the cuttings dryer is to separate the solid particles in the suspension from the liquid by centrifugal force. Here's a detailed explanation of how it works:

The cuttings dryer is a vertical scraper discharge drying centrifuge, which is composed of a drum, a filter medium, a scraper and the main body of the centrifuge. The drum is a cylindrical container with many small holes on the outer surface, and the inner surface is covered with filter media. The drum can rotate around its axis.

The cuttings dryer is a continuous working device, the suspension is continuously input into the drum, and with the rotation of the drum, the solid and liquid in the suspension are separated.
When the drum rotates at high speed, the suspension rotates with it. Due to the centrifugal force generated by the rotation, the solid particles in the suspension are forced to move along the drum wall by the outward centrifugal force. Centrifugal force can reach hundreds of times that of gravity, which intensifies the filtration process.
  
The filter medium covered on the drum wall acts as a filter. The liquid components in the suspension are thrown out through the filter media and the holes on the wall of the drum, forming a thin film flow, and discharged out of the machine through the drainage system. The solid particles are trapped on the surface of the filter medium due to their large mass and the influence of centrifugal force.

As the drum rotates, solid particles are gradually deposited on the filter medium to form a solid filter residue. The scraper is located on the inner surface of the drum wall. With the rotation of the drum, the scraper scrapes off the solid filter residue and discharges it through the discharge port.

The cuttings dryer continues to input the suspension, centrifuge and discharge the solid filter residue until all the suspension to be treated passes through the process and completes the separation.
