Working Principles and Features of Screw Sand Washing Machine

Screw sand washing machine is a kind of bucket-wheel washing equipment. It can be used to remove the stone powder and clay in the gravel. Its novel sealing structure and reliable transmission ensure the cleaning effect. When this sand washer is in operation, the motor drives the impeller to rotate and the sand and gravel enters the washing chute through the feeding chute. Under the role of the impeller, the materials roll and grind against each other, which is not only conducive to remove the impurities on the surface of the sand and gravel, but also is helpful to destruct the water vapor layer that is coated on the sand and gravel in order to facilitate dehydration.

At the same time, the addition of water to form a strong water flow can timely wash away the impurities that will be discharged out from the outlet of the washing chute. The clean sand and gravel will be taken away by the blade and then the gravel is poured into the discharging chute from the rotating impeller discharge chute, completing the cleaning operation. 1, the screw washing machine is featured with simple structure and stable performance. The separation between the impeller driving bearing device and water and materials can greatly avoid the damage of the bearing because of the pollution of the water, sand and other pollutants.
