technical field

The invention relates to the technical field of ore washing, in particular to a sand washing machine.

Background technique

The sand washing machine is a wheel-bucket sand washing equipment used in conjunction with the sand making machine. It cleans the dust and soil and other impurities in the sand and gravel products, thereby improving the quality of the sand. When working, the motor drives the impeller to rotate slowly after being decelerated by the V-belt, reducer, and gears. The sand enters the sand washing box from the feeding trough, rolls and grinds each other under the drive of the impeller, and removes the impurities covering the surface of the sand. At the same time, water is added to form a strong water flow, which will take away impurities and foreign matter with small specific gravity in time, and discharge them from the washing tank at the overflow port. The clean sand will be taken away by the impeller, and finally the sand will be poured into the discharge tank from the rotating impeller to complete the sanding process. Cleansing effect of the stone. However, due to the large amount of water contained in the sand and gravel in the existing sand washing machine, when dumping, part of the cleaned sand and gravel adheres to the outer wall of the impeller, and enters the sand washing box again with the rotation of the impeller, resulting in ineffective cleaning and reduced The cleaning efficiency is reduced, and water resources are wasted.
