A 100 ton per hour silica sand purification plant in cost about 150,000 USD. Product Advantages (1) Extracting the fine material in the raw material slurry firstly can effectively reduce the load of the subsequent equipment and reduce the type of the equipment, thereby achieving the purpose of small investment and small floor space, reducing wear and tear on the equipment and prolonging the service life. (2) The fine sand recovery machine has reasonable waterway design, including backwater regulation and overflow regulation, which makes the recovery effect of the whole machine more ideal. The internal structure of the concentration tank is designed according to the principle of fluid dynamics, fully considering turbulence and settlement. In other aspects, in the case of the same amount of processing, the volume is smaller, and the amount of flocculating agent is more economical; the filter press adopts fully automatic program-controlled pulling plate technology, and a pressure gauge
