The main mineral component of silica sand is quartz, which is formed by crushing silica minerals to make sand. There are many types of silica sand, which can be divided into artificial silica sand and natural silica sand. Natural silica sand can be divided into washed sand, scrub sand and selected sand. Silica sand is a refractory particle with a particle size ranging from 0.020mm to 3.350mm, and is widely used in many industries.
The silicon ore is initially crushed by the jaw crusher, and the produced coarse material is transported by the conveyor to the cone crusher for secondary crushing. The finely crushed silica is sieved into the vibrating screen to separate out two kinds of stones. The materials that meet the feeding particle size are processed into the sand making machine, and the materials that do not meet the feeding particle size of the sand making machine are subjected to secondary crushing to meet the particle size requirements. Then, the silica sand that meets the specifications is magnetically separated by the magnetic separator and enters the cleaning water tank of the sand washing and recycling integrated machine. After that, the coarse-grained materials are sent to the dewatering screen by the salvaging wheel for dehydration. The tail water is pumped into the separator by the slurry pump, and the sediment is separated by the separator. After recovery, the fine material is discharged to the screen surface of the dewatering screen and the coarse material is evenly mixed and dehydrated before discharging. At the same time, the sludge-water suspended matter treated by the separator is discharged into the sewage tank, and then the tail water is pumped from the sewage tank into the concentration tank by the pump for the mud-water separation operation. The concentrated mud is pumped into the plate and frame filter press through the bottom of the filter tank to achieve dry stacking. After pressure filtration, the clean water enters the clean water tank to realize the recycling of clean water.
