Presently, the most man-made sand production line adopts wet process. No matter which model sand washer they put in use, the biggest weakness is serious loss of fine sand ( below 0.16mm), sometimes the loss is up to 20%. The problem is not only the sand loss itself, but also results in unreasonable sand gradation and more coarse fineness module, it influences the sand quality. Moreover, excessive sand flow away leads to environmental pollution. In response to this problem, our company elaborates SS series fine sand recycling system. This system absorbs world’s advanced technology, and takes the view of practical working situation. It is ranged in top class international. The applicable fields are aggregate processing system for building hydro power, processing system for glass raw material, man-made sand producing line, coarse coal slime recycling and environmental protection system (mud purification) in coal preparation plant, etc. It can works effectively in collecting fine sand.
Structure: It is mainly composed of motor, residue slurry pump, cyclone, vibrating screen, rinse tank and recycling box, etc.
Working principle: The compound of sand and water is transported to the cyclone by pump, and the fine sand after centrifugal classification concentration is provided to the vibrating screen by the grit setting mouth, after vibrating screen dewater, the fine sand and water are effectively separated. Through the recycling box, little fine sand and mud return again to the rinse tank, and then they are exhausted from the discharge hole when the rinse tank liquid level is too high. The material weight concentration recovered by the linear vibrating screen is 70%-85%. Adjusting the fineness module can be realized by changing the pump rotating speed and pulp concentration, regulating the overflow water yield and replacing the grit mouth, thus achieves its three functions—washing, dewater and classification.
