What is Volute?

Design and Principle

Design and Function

Layers of spacers, fixed and moving rings, construct the cylinder. Moving rings, which are slightly smaller than the outer diameter of the screw and slightly narrower than the spacers, are located between the fixed rings and are moved by the screw.

The moving rings continuously clean sludge out of the gaps and prevent clogging.

Mechanical Principle

The initial section is the thickening zone where the filtrate is discharged.

The pitch of the screw narrows and gaps between the rings decrease toward the end-plate, where sludge cakes are discharged.

The pressure in the dewatering drum increases as the pitch of the screw narrows. The end-plate further increases the pressur, and dewaters sludge.
