Ball Mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed system, with oversize material continuously being recirculated back into the mill to be reduced. Various classifiers, such as screens, spiral ...

Ball Recycling

Only around 1 to 2% of aluminum is lost when shredding the bales, and another 2 to 3% due to oxidation in the furnace. Total metal losses in the recycling process can be between 3 to 5%. When factoring in the recycling rate and the material losses in recycling, it is clear that, as we move toward near 100% collection, yields really matter.
