LW-NB Series Decanter Centrifuge

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.

Detail

LW-NB Series Decanter Centrifuge 

Product Principle

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. 

Product Structure 

LW Series 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 and automatic control system, and can perform solid-liquid separation, size grading, solid-phase dewatering, liquid-phase clarification and other operations for multiple suspensions with large differences in materials.
