Main Equipment--- LW Decanter Centrifuge
LW decanter centrifuge is one of the main equipments in the dewatering system. With large bowl angle, BD plate and large length-diameter ratio; equipped with the high-torque planetary gearbox or hydraulic driving system, it features high rotating speed, large torque, and small differential speed.
Bowl speed: high rotating speed design and high centrifugal force, that effectively remove particles ≥3μm;
Length-diameter ratio: actual effective L/D ratio is higher than 4.1; long drying area maximum the settling time and dewatering time of sludge;
BD plate: A round stop is mounted between the conveyor settlement area and the drying area. The sludge in the settlement area is compressed first and then enters into the drying area, minimum the moisture rate of sludge.

Auxillary Equipment1---Electric control system
Auxillary Equipment 2---Polymer mixing and dosing device
Note: We can also supply two-chamber polymer mixing and dosing device.
Auxillary Equipment 3---Sludge crushing & cutting machine
The cutting machine is mainly used to crush large objects such as woods, textiles, plastics, rubber, bones, leather and glass in the sludge with solid content ≤5, so as to ensure the proper operation of dosing pump, centrifuge and instruments in the downstream system. The cutting machine features large capacity and long service life blade.
Auxillary Equipment 4---Sludge feed pump
This pump is a positive displacement pump, the rotor with large transmission distance, large tooth height and small inner diameter will convey the sludge from suction end to exit end. It is mainly used for transport of 0.2~5% concentration sludge and polymer. Flow rate is controlled by inverter.
Auxillary Equipment 5---Shaft-free screw conveyor
Model LS Shaft-free screw conveyor mainly consists of drive device, shaft-free screw vane, U-shaped changeable abrasion-resistant scaleboard and frame. It is mainly used for transporting sludge cake from the centrifuge to outdoors sludge heaping field or vehicle. Entire work is done at close state so as to keep environment clean.
