Decanter centrifuge is a horizontal screw discharge, continuous operation sedimentation centrifuge.
The working principle of the decanter centrifuge is: the rotating drum and the screw rotate at a high speed in the same direction at a certain differential speed. The material is continuously introduced into the inner cylinder of the conveying screw by the feed pipe of the decanter centrifuge, and then enters the rotating drum after being accelerated. Under the action of the centrifugal force field, The heavier solids in the decanter centrifuge are deposited on the wall of the bowl of the decanter centrifuge to form a sediment layer. The conveying screw continuously pushes the solids deposited in the decanter centrifuge to the cone end of the rotating drum, and is discharged out of the machine through the slag discharge port. The lighter liquid phase in the decanter centrifuge forms an inner liquid ring, which continuously overflows the drum from the overflow port at the large end of the drum, and is discharged out of the machine through the discharge port. The decanter centrifuge can continuously feed, separate, wash and discharge materials at full speed. It has the characteristics of compact structure, continuous operation, stable operation, strong adaptability, large production capacity and convenient maintenance.
The decanter centrifuge is suitable for separating suspensions containing solids with a particle size greater than 0.005mm and a concentration range of 2-40%.
