GN Sludge Dewatering Centrifuge Introduction

1. What is a sludge dewatering and sludge thickening Decanter centrifuges usd for?

1.1 GN Sludge dewatering Decanter centrifuge is mainly composed of a feed tube, a bowl, a screw conveyor, and solid/liquid phase discharged outlets. In the separation process, the raw material is pumped into the bowl (also called a rotating drum) through the feed tube. Then, the bowl and the screw conveyor rotate at a high speed in the same direction at a differential speed. By centrifugal force, the solid particles with higher density are collected and compacted on the wall of the bowl, then be pushed to the outlet of the bowl by the screw conveyor. The clarified liquid leaves through a paring disc (internal centripetal pump). Eventually, the separation of the solid and liquid is achieved.

1.2 GN sludge centrifuge is professional industrial separation equipment for sludge dehydration treatment. The central part is composed of a cylindrical bowl. When the equipment is working, the bowl rotates at high speed to separate the wastewater liquid from the solid and discharge the liquid and solid substances separately through the discharge port. The equipment has an automatic control system and can work continuously without interruption. Which can significantly improve the efficiency of sludge treatment.

2. GN Sludge dewatering decanter centrifuge features and working principle

2.1The bowl and screw of the decanter centrifuge rotate to the same direction with a certain differential speed. The material is continuously introduced into the screw shaft, and then flies to the bowl after its speed highly increased. Under the action of centrifugal force field, heavy solid phase is deposited on the bowl wall to form sediment layer. The solid is continuously pushed to the cone section of the bowl and discharged through the slag outlet. The light liquid phase forms an inner liquid ring, which is continuously overflow out of the bowl from the liquid outlets at the big end of the bowl Straight section of the bowl is the clarification area, and the cone section is the extrusion drying area.

2.2 T Series Decanter Centrifuge Features

The beach angle of the T Series dewatering decanter centrifuge is 8.5 Degree, which makes the decanter centrifuge cone section longer, that is, the drying and dewatering area of the decanter is longer, which is conductive to the dewatering performance of T series decanter centrifuge, and much drier solid cakes discharged. The beach angle of 8.5 degree will make the slag discharging more smooth so as to increase the amount of slag discharging.
