For the current artificial sand production lines, the majority adopt the wet method production process. No matter what type of sand washer, its biggest shortcoming is serious loss of fine sand (grains with a grain size of less than 0.16mm), in some sand washer, over 20 percent of fine sand is lost, this shortcoming not only reduces the output, but also seriously affects sand gradation, the unreasonable gradation is caused, and the fineness modulus is relatively big, so that the product quality of the sand-making machine is greatly lowered. Excessive discharge of fine sand will also possibly cause environmental pollution. In order to solve the problem, the company develops the WS fine sand recovering device. The system, a fine material recovering device with world advanced level, is designed by absorbing the world advanced technology and combining actual conditions of China. The machine is widely applied to sand aggregate processing systems of hydraulic power stations, glass material processing systems, artificial sand-making production lines, recovery of coarse coal slurry of coal separating plants, environmental protection projects (slurry purification, etc. ), etc., and can effectively solve the problems of recovery of fine sand.
