Automatic Spiral Sand Water Separator for Grit Classifier

BOEEP automatic spiral sand water separator which uses spiral to lift the grit for classification is full automatic.
  • WSF260
  • WSF

Product Introduction

Boeep WSF grit classifier belongs to light type grit and water separation equipment. It can either be a stand-alone unit or it can work in conjunction with the Grit Vortex Separator. The concentrated grit from the Grit Vortex Separator is airlifted or pumped to the classifier for further separation, dewatering and removal. The WSF is maily used for municipal waste water treatment plant.

Structure and Working Principle

Screw type sand and water separator is composed of driving unit, auger, water tank, U-shape chute and liner strip.

 working principle of grit water separator

structure and dimension of grit classifier

The grit classifier consists of a slope bottom tank and a screw conveyor. The grit settled at the bottom of the tank is collected, lifted by the screw conveyor( 25degree) and then drained and discharged to make sure the moisture content of the discharged grit flow be less than 60%. The screw diameter and consequently the grit classifier model varies according to the volume of grit to be dewatered.


1-Using the screw conveyor without the bearing underwater, to decrease maintenance needs.

2-Lined inside the U trough with low friction, wear resistant material, easy to be changed.

3-Integrated equipment which is convenient for installation and transportation.

4-Cost-effective, easy operation, easy installation.
