GreyStone’s dewatering screen uses a patented flume that allows the operator to retain all fines discharged from the dewatering screw while producing sand and gravel products with moisture content as low as 7 to 12 per cent.
The screen produces a caked, dry sand product that cannot be achieved with an inclined dewatering screw. It is wheel-mounted for easy transportation and can be connected to a washing screw for on-demand production.
It also features a 0.25mm screen opening that considerably reduces the amount of material that can fall through.
