The decanter centrifuge is a horizontal spiral unloading and continuous operation sedimentation equipment.
The drum and the spiral rotate at the same direction and at a high speed with a certain differential speed. The material is continuously introduced into the feeding screw inner cylinder from the feeding tube, and enters the drum after accelerating. Under the action of the centrifugal force field, the heavy solids are deposited on the drum wall A sediment layer is formed. The conveying screw continuously pushes the deposited solid phase to the end of the drum cone and is discharged out of the machine through the slag discharge port. The lighter liquid phase forms an inner liquid ring, which continuously overflows the drum from the large-end overflow port of the drum, and is discharged out of the machine through the liquid discharge port.
This machine can continuously feed, separate, wash and unload at full speed. It has the characteristics of compact structure, continuous operation, stable operation, strong adaptability, large production capacity, and convenient maintenance. Suitable for separating suspensions containing solids with particle size greater than 0.005mm and concentration range 2-40%. Widely used in chemical, light industry, pharmaceutical, food, and other industries.
