Maintaining Your Attrition Mill Eagle Iron Works

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.
