A sludge dewatering centrifuge is a mechanical device that uses centrifugal sedimentation to concentrate or dewater sludge. It mainly consists of a rotating drum, screw conveyor, differential gear, main bearing, and control system. It achieves solid-liquid separation through centrifugal force generated by high-speed rotation: sludge particles form a solid ring layer which is discharged by the screw conveyor, while liquid forms a liquid ring layer which overflows through a weir. It has continuous operation capability.
The equipment adopts a closed structure and, in conjunction with an automatic flocculant dosing system, can handle solid-liquid separation in various scenarios such as municipal sewage, chemical sludge, and food waste. Its core advantages include no need for filter media, high degree of automation, and high solids recovery rate. However, it has limitations such as relatively high operating noise and high moisture content in the dewatered sludge. Typical applications include papermaking, printing and dyeing, and oilfield mud treatment, with compatible models covering different industrial processing capacities.
