New Attrition Mill from Superior Industries

A quieter and more energy-efficient option for sand washing and cleaning applications

Minnesota-based Superior Industries Inc., US manufacturers and global suppliers of bulk material processing and handling systems, have launched a new Attrition Mill within their line of washing and classifying machinery.

The new machine is said to provide an efficient solution for sand applications, including the disintegration of conglomerates, material separation, and surface cleaning and polishing. 

Coated with long-lasting urethane, the Attrition Mill’s tank and propellers are built to endure the arduous nature of tough sand-cleaning applications.

Superior engineers also designed the Attrition Mill with round tubs in order to eliminate swirling and corner material collection.

In addition to its efficient, minimal design, the Attrition Mill is equipped with a large, watertight sealed door that makes maintenance convenient for machine operators by eliminating the heavy lifting that comes with drive removal. 

According to John Bennington, Superior’s director of washing and classifying, the Attrition Mill’s 50hp engine produces the same capacities as similar machines with three times the power, providing operators a quieter and more energy-efficient process. 

With an outside diameter of 54in and a height of 72in, the Attrition Mill is manufactured for capacities ranging from 75–120 tonnes/h.
