LW520W Series Stainless Steel Wastewater Sludge Dewatering Decanter Centrifuge

Sludge dewatering decanter centrifuge is able to perform continuous feeding, separation and discharge during full-speed operation. It is featured compact structure, easy sealing, stable operation, low noise level, large possessing volume, low energy consumption, high degree of automation, low labor intensity, convenient operation and maintenance, wide application scope, etc.

Product Details

Structure Theory
The imperforate drum was attached with a wood-cored discharge screw; the two simultaneously co-rotate at high speeds with certain speed differential, which is generated from the drive system and differential. The suspension enters the filling screw cavity through the feeding tube, then, after accelerated, enters the drum. Under the centrifugal force, the solid-phase grain with larger density sediments to the drum inner wall, forming a dreg annular layer, which is continuously pushed towards the smaller side of the drum by the discharge screw, so as to discharged out of the drum, while the clarified fluids is continuously discharged out of the drum through the overflow port at the larger side, thus enabling the solid-liquid separation of the suspension.
The Performance Feature
Sludge dewatering decanter centrifuge is able to perform continuous feeding, separation and discharge during full-speed operation. It is featured compact structure, easy sealing, stable operation, low noise level, large possessing volume, low energy consumption, high degree of automation, low labor intensity, convenient operation and maintenance, wide application scope, etc.
