 working principle of screw grit removal

structure and dimension of screw grit removal

The screw type grit removal is composed 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.


  • Using the screw converyor without the bearing underwater, to decrease maintenance needs.

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

  • Integrated equipment which is convenient for installation and transprotation.

  • Cost-effective, easy operation, easy installation.
