Technical process
Sucked by the cutter head pump the raw material into speed reducing box to get a steady movement and then into trommel screen to be classified into 2 size,the big one>6mm,the small one≤6mm the big one >6mm useless to get rid to scrap area;
The small one into gold concentrator by sand pump within the mineral box,the concentrate can be automatic discharged into concentrate box,waste material to get rid to scrap area.
