At present, most of the existing artificial sand production lines adopt the wet production process. No matter what type of sand washing machine is adopted, its biggest disadvantage is that the sand washing (particles below 0.16mm) has serious loss, and some even lose more than 20%. This not only loses the output, but also seriously affects the gradation of the sand, resulting in unreasonable gradation and coarse fineness modulus. The product quality of machine-made sand is greatly reduced. Too much sand washing will cause environmental pollution.

In order to solve the above problems, our company developed WS series sand washing and recycling system, which is an advanced fine material recycling device designed by our company based on the advanced technology of foreign countries and the actual situation of our country. Widely used in hydropower station sand aggregate processing system, glass raw material processing system, artificial sand production line, coal preparation plant crude slime recovery and environmental protection projects (mud purification, etc.), can effectively solve the problem of fine sand recovery.

The slurry pump will transport the sand and water mixture to the cyclone, the centrifugal classification concentrated fine sand is provided to the vibrating screen through the sedimentation nozzle, the vibrating screen after dehydration, the fine sand and water are effectively separated, a small amount of fine sand, mud and so on through the reverse tank and back to the cleaning tank, the cleaning tank level is too high, the discharge port, the linear vibrating screen recovery material weight concentration of 70%-85%. Adjusting the fineness modulus can be achieved by changing the pump speed, changing the mortar concentration, adjusting the overflow water and replacing the sand nozzle. Thus to complete the cleaning, dehydration and classification of three functions.
