CLS – SAND SEPARATOR

This machine separates sands by extraction, from wastewater of various nature: municipal, industrial. It is also called sand classifier or sand washer.
It consist of: • a decantation hopper • a shaftless screw conveyor, conveniently go into proportion, for extraction, transport and unloading sands • U-section trough The wastewater (water + sands) enters the hopper through a flanged inlet: here, decantation and settling of the solid particles takes place on the bottom of the tank.
The special screw conveys the separated material toward the discharging spout. The clean water comes out of the hopper thanks to an overflow system linked to a flanged outlet
The low rotational speed and the special anti-wear covering fixed on the transport section assure an high efficiency and a low wearing of the machine’s internal parts.

ADVANTAGES

• no mechanical parts in contact with the sewage
• low erection and maintenance costs
• no hanging bears
• possibility of sand washing before discharging
• completely close machine
