How it works:

Street sand, filter sand and similar materials can be handled.
The sand/water mix is pumped or fed into the separation tank where sand settles to the washing zone and is mechanically agitated and washed.
After washing the screw conveyor dewaters & conveys the sand.
Excess water during pumping flows out over a weir and is led out.
The organic material is led out separately or through the same outlet.
