LWZ screen bowl decanter centrifuge is integrated machine for concentrating, settling, and dewatering which combine the clarifying benefits of the solid bowl decanter centrifuge and add a final dewatering screen section, and are mainly composed of rotating assembly (the bowl, the scroll conveyor, the shaft neck assemblies of large bowl end and small bowl end), a planetary gear differential, feed tube, frame, casing, backwashing device, power system, lubrication system and other components.

LWS Series Three-phase Decanter Centrifuge is mainly composed of rotating body combination (screw and basket etc.), planetary gear differential, double motors (main motor and auxiliary motor), double frequency converters, integrated base, fully-closed housing, feeding pipe assembly, adjustable centripetal wheel, hood and automatic control system, and can perform liquid-liquid-solid or liquid-solid-liquid three-phase separation for multiple suspensions with large differences in materials.

Host is turned on and automatically accelerates up to preset speed. Open the feeding valve and the suspension to be separated enters into stock bin of screw pusher through feeding pipe, and enters basket from bin outlet after preliminarily accelerating. The suspension in basket is divided into two phases quickly under the action of centrifugal force. The differential action of differential gear makes relative movement generated between screw pusher and basket, and the heavier solid phase settles on inner wall of basket and is screw pushed to drying area at small end of basket for further dewatering, and discharged through drainage port. At the same time, the clear separated liquid is discharged from overflow port at big end or discharged by using centripetal pump. 

The centrifuge starts and automatically accelerates to the predetermined speed. The feed valve is opened, and the suspension to be separated enters the inlet distributor of the scroll conveyor through a stationary inlet tube and is accelerated smoothly into the bowl.
