Attrition Mills
Attrition Mills, similar with the Lump Breakers are combine attrition and screening of No-Bake sand, green sand lumps or core butts into a single unit. Attrition Mill is a rugged, heavy-duty unit that is designed to provide constant, reliable reclamation year after year. Models up to 5 ton per hour throughput are available. It is a top loading mill that contains no cross bars or grates to interfere with inspection of the primary screen or removal of tramp metal, gaggers, etc. All interior surfaces are protected by cross-ribbed wear plates.
The attrition mill utilizes an adjustable output 3 phase vibrator which is bottom mounted to provide maximum agitation of the sand mass. Vibrator horsepower ratings for the R-1, R-3, R-5, and R-10 are 2, 4, 5, and dual 5 horsepower, respectively.
The attrition mill includes as standard a three sided tapered load frame to aide in loading efficiency
Common Benefits
