The raw ore is crushed to below 30mm by crushing equipment such as crushers and cone crushers. Raw materials smaller than 30mm are fed into rod mills or other sand making equipment for sand production. The mortar produced by the rod mill is separated by a hydraulic classifier and a blocked settling machine to obtain qualified particle sizes of 26-140 mesh; Qualified quartz sand enters the magnetic separator for iron removal and purification; After magnetic separation, the finished sand is dehydrated through a dewatering screen and sent to the finished product warehouse for storage; The tail mud and tail sand are separated and stacked separately. Water can be recycled and the entire production process is environmentally friendly and pollution-free.
