Superior’s patent-pending Attrition Mill is beneficial in a number of sand applications including disintegration of conglomerates, material separation, and surface cleaning and polishing. Additionally, the Attrition Mill improves material strength by removing mineral coatings. Lined with urethane for added protection, this unit’s durability is unmatched in the market. A 50-hp engine produces the same capacities as similar machines with three times the power, giving operators a quieter and more energy-efficient process.
