[0002] Horizontal spiral unloading sedimentation centrifuge is a highly efficient solid-liquid separation equipment, widely used in chemical, pharmaceutical, food, environmental protection and other fields. Its working principle is to use the centrifugal force to separate solid particles and liquids of different densities. The equipment is mainly composed of a drum, a screw conveyor, a differential, a motor and other parts. The inner wall of the drum is smooth and the speed is adjustable. It is connected to the motor through a differential to achieve high-speed rotation. The screw conveyor is installed in the drum and is driven by the motor to rotate, pushing the solid particles to the outer edge of the drum, thereby achieving solid-liquid separation.
