Volute Screw Press Sludge Dewatering Machine 

Dewatering Principle

the screw press sludge dewatering machine a filter device formed by stacking a fixed ring and a moving ring, and the screw shaft penetrates through it. the front section is the concentration section, and the rear section is the dewatering section.

the filter slit formed between the fixed ring and the moving ring and the pitch of the screw shaft gradually decrease from the concentration part to the dewatering part.

while the rotation of the screw shaft pushes the sludge from the thickening section to the dewatering section, it also continuously drives the traveling ring to clean the filter gap to prevent clogging.

 

Usage

 

It can be widely used for sludge dewatering in various industries such as municipal sewage, food

Beverages, slaughter and breeding, printing and dyeing, petrochemicals,paper-Making, leather,

Pharmaceuticals, etc.
