Features

The screw body is consist of fixed rings, movable rings, screw bars, gasket and the main screw. Whileworking, the movable rings will move as a cycle around the main screw, however, the gasket ensures there have some gap between the fixed ring with the movable ring, so that avoid block torealize self-washing function, and thus greatlydecrease the consumption of washing waster. 

High Efficient Sludge Squeezing Technology: to greatly deceatse the final cake moisture, we adopts three special structures

1.The screw distance is decreasing from inlet (bottom side) to outlet (top side). At the same time, the diameter of the screw is becoming bigger from inlet to outlet.

2.On the main shaft, in the cake discharging tank,there is a baffle and there is a gap between the balffle with the dewatering roller, so the ensure therewill have some pressure to the sludge. Thus it can perfectly squeeze out the water and realize best filtering performance.

3.Screw Induration Technology: On the surface ofthe screw leaf, it is processed by the induration materials, and this ensures the hardness can be 1000 HV and the adhesive force is bigger than 70 MPa, so It's difticult to cause deformation, and can have long life-span. Four filter, the normal parts are cut by cutting machine or water cutting machine, and the key parts are cut by laser to make sure the precision.
