The horizontal screw centrifuge mainly consists of a conical drum, a straight drum, a screw conveyor, a differential speed reducer, bearing housings at both ends, a feeding system, a base, a casing, main and auxiliary motors, and an electrical control system. The main motor drives the drum via a belt, while the auxiliary motor drives the differential speed reducer via a belt, causing the screw conveyor to rotate and creating a speed difference with the drum. Under the powerful centrifugal force generated by the high-speed rotation of the drum, the materials are continuously separated.
The drum and screw rotate at a high speed with a certain speed difference. The material enters the screw feed chamber through the feed pipe, accelerates through the distribution holes, and then enters the drum. Under the action of centrifugal force, the heavier solid phase deposits on the inner wall of the drum, forming a sludge layer. The screw conveyor continuously pushes the deposited solids towards the conical end of the drum, through the drying zone, and out of the machine through the discharge port. The lighter liquid phase forms an inner liquid ring, continuously overflowing from the large end overflow port of the drum and being discharged through the liquid outlet of the casing.
