Spiral Sand Gravel Washer for Mineral Processing 

The Spiral Sand Washer machine is a type of Auxiliary Crushing Equipment used in crushing plant to clean and separate materials such as sand, gravel, and crushed stone. The machine uses a spiral-shaped roller to move the materials through the water, scrubbing and cleaning them as they go. The water and dirt are then separated, and the clean material is discharged from the machine. It is designed to remove impurities such as dust, clay, and organic matter from the sand and gravel, and then separate them according to size. The machine works by using a spiral blade to push the sand and gravel up the inclined trough, where the water is added to wash and separate the materials. The clean sand and gravel are then discharged at the bottom of the machine, while the impurities are carried away by the water. Spiral sand washers are commonly used in construction, quarrying and mining industries.
