Working principle of sand washing machine:

The sand water mixture enters the cleaning box, which is separated by impeller separator, and then enters the lower dewatering screen for dehydration treatment. The waste water (containing a large amount of fine sand, mud, dust and other impurities) overflowed from the cleaning box is transported to the high-pressure separator by vacuum high-pressure pump.

And then the fine sand after centrifugal classification and concentration is discharged into the upper layer of dewatering screen through the sand settling nozzle, The waste water, mud, dust and impurities in the cleaning box are discharged into the high-level return tank through the overflow port of the high-pressure separator. The coarse sand of the finished product is discharged from the upper layer, and the fine sand of the finished product is discharged from the lower layer, or the coarse sand and fine sand are mixed (it can be adjusted according to the customer’s requirements).
