Material ON MATERIAL SCRUBBING. Servicing a niche group of industries like frac sand and glass production, attrition mills produce a more durable product with better sand equivalency. Inside each tub, a set of opposing pitch impellers force particles to collide. This action breaks up particles but also cleans and polishes the surface of the sand.
