DESCRIPTION AND OPERATING PRINCIPLE
Grit washers consist of a tapered settling hopper equipped with an agitator and connected to a solids screw extractor fitted with a central shaft. Normally, helicoid flights are connected directly to the gear motor via a flanged shaft. A device located at the bottom of the hopper injects clear water in the opposite direction to remove organic substances from the sand in order to make it reusable. The water that flows in the opposite direction facilitates the ascent of organic substances, which are discharged at regular intervals through a special duct. The clarified water, instead, is discharged through a second duct located at the top of the tapered hopper. The water is churned constantly to enable the sand to pass from the hopper to the discharge screw, which conveys it towards the outlet.
