SVS スクリーンボウルデカンター

The Screen Bowl Centrifuge is a centrifuge optimized for separation, classification, and dehydration of slurry containing crystalline solids.

Overview

This centrifuge has a screen part for centrifugal filtration added to the conical part of the decanter type centrifuge. This type is suitable for dehydrating slurry containing incompressible and relatively large solid particles. Thus far, this type has been installed for separation, classification, and dehydration processes of fine coal, many crystalline products, etc.

Characteristics

1. Extremely low water content results from the doubling effect developed through centrifugal separation and screen filtration.
In addition, large-capacity processing is possible.
2. Low driving power and wear
Operation under a low rotation speed is possible thanks to the extremely highdewatering capacity.As a result, mechanical wear is reduced.
3. Simultaneous washing of crystalline material is also possible.
Crystalline washing performance is excellent because of the rinse liquid spray over the screen segment. This leads to a reduction in the process time.

Structure

SVS スクリーンボウルデカンター構造
  1. Supplied raw slurry is separated into solid and liquid via centrifugal force, and centrate (clear liquid) is continuously discharged over the weir plate (dam plate) at the end of the bowl.
  2. The solid material settled on the inner wall of the bowl is conveyed to the conical part via a screw conveyor and preliminarily dewatered.
  3. The solid material is transported to the screen part, further filtered/dehydrated, and discharged outside the machine. Rinsing of solid matter is possible by feeding rinse liquid over the screen section inside the machine.
