Maintaining Your Attrition Mill - info.eagleironworks.com

Attrition Mills provide high-intensity scrubbing to remove coatings and stains from sand feeds and to disintegrate lignite. Two five-bladed propellers per shaft force the sand grains to grind against each other. This provides the scrubbing action needed to remove those coatings and stains and gives direction of movement to the material, allowing it to travel from cell to cell inside the machine.

US Patent for Attrition mill Patent (Patent # 5,797,550 ...

An attrition mill comprising a grinding chamber (1), an axial impeller (10), a chamber inlet (3) for admitting coarse particles and a separator comprising a chamber outlet (6) through which fine particles exit from the chamber. The mill is characterized in that a classification as between coarse and fine particles is performed in the mill upstream of the separator.
