A high-precision countercurrent sand washing machine has been developed.
Utilizing the principle of hindered settling and classification, the sand washing equipment classifies particles based on their settling velocity differences through an upward flow. Innovative structures such as a low-turbulence swirling inlet well and an inclined plate flow-blocking device reduce the impact of turbulence at the inlet and outlet on sedimentation within the washing tank, thereby improving classification accuracy. This allows for achieving a finished fine sand product with a clay content of less than 3% while maintaining a +0.074 mm recovery rate of over 95%.
