What Is a Decanter Centrifuge?
A decanter centrifuge, formally known as a horizontal screw discharge sedimentation centrifuge, is a continuous-operation sedimentation equipment widely used in industrial applications. It separates solid particles from liquid phases using high centrifugal force generated by a rotating bowl, making it essential for solid-liquid separation processes across numerous industries.
Working Principle
The rotating bowl and the screw conveyor rotate at a differential speed in the same direction. The feed material is continuously introduced into the screw conveyor's inner cylinder through the feed pipe, then accelerated into the rotating bowl. Under centrifugal force, heavier solids deposit on the bowl wall forming a sediment layer, which is continuously pushed toward the conical end by the screw conveyor and discharged through solids discharge ports. The lighter liquid phase forms an inner liquid ring, overflowing through the large-end overflow ports and draining from the machine. The system operates continuously with feeding, separation, washing, and discharging at full speed.
