GN Company Supplied Decanter Centrifuge for African Client

GN Company is a professional manufacturer of Decanter Centrifuge, and is capable to supply decanter with bowl diameter from 220mm to 760mm.

The decanter centrifuge is a spiral unloading sedimentation centrifuge. It is mainly composed of a high-speed rotating drum, a screw conveyor with a hollow shaft and a differential with the same rotation as the rotating drum and a slightly lower speed than the rotating drum.

When the suspension to be separated is sent into the drum by the hollow shaft, it is immediately thrown into the drum cavity under the action of the centrifugal force generated by the high-speed rotation.

The high-speed rotating drum generates strong centrifugal force to sling the solid particles with higher density than the liquid phase on the inner wall of the drum to form a solid layer (because of the ring shape, called the solid ring layer); due to the low density of water, the centrifugal force is small Therefore, the liquid layer can only be formed inside the solid ring layer, which is called the liquid ring layer.

Due to the different rotation speeds of the screw and the drum, there is a relative movement (that is, the difference in rotation speed) between the two. The relative movement of the screw and the drum is used to slowly push the sludge in the solid ring layer to the cone end of the drum and pass through the drying zone. After that, it is continuously discharged from the outlets distributed around the circumference of the drum; the liquid in the liquid ring layer is continuously discharged from the weir to the outside of the drum by gravity to form a separated liquid.

Welcome to contact GN Company, and they would offer one stop turnkey solution for clients’ project.
