Washing sand recycling machine working principle. After the natural silica sand is classified and filtered by the screening equipment, the qualified products flow into the spiral sand washing machine through the launder or the pipeline. It is fully cleaned, soaked and broken by a screw mixer (for larger muddy and extra-large effect), sandstone is fully separated from impurities and mud.

Fine sand and muddy water are deposited in the tail of the spiral washing, and the recovery of fine sand is achieved through a concentration and recovery device. Then the coarse and fine sand enters the wheel washing machine at the same time for secondary cleaning to achieve complete separation of the sediment.
