FG series spiral sand washer
FG series spiral sand washer is a mechanical gradingequipment which utilizes the principle that solid particles ofdifferent size and gravity have different settling velocity, bywhich fine particles outflow with the water,while the coarseparticles sink to the slot bottom and are discharged upwardby the spiral. The equipment is widely used in ore dressingplants for establishing a closed loop procedure for splitrange and split stream operation together with ball grindingmill, or used in gravity mill for grading ore sand and fine siltas well as ore dewatering and feeding.
