Abstract: Sedimentation centrifuge is widely used in the field of solid-liquid separation. Centrifuge separation performance is an important performance index of equipment. This paper introduces the design principles and structure of HDPE horizontal sedimentation centrifuge. It analyzes the factors affecting the centrifuge separation performance from such aspects as the centrifuge rotary drum diameter, length-diameter ratio of rotary drum, half-cone angle of rotary drum, particle size and material viscosity and so forth in the hope of providing guidance for production and operation and providing reference for the operation of related equipment of similar devices.

Key words: centrifuge, rotary drum, separation performance, residual humidity, particle size
