AP42, CH 12.8: Secondary Aluminum Operations

An example of mechanical cleaning is the dry milling process. Cold aluminumladen dross and other residues are processed by milling and screening to obtain a product containing at least 60 to 70 percent aluminum. Ball, rod, or hammer mills can be used to reduce oxides and nonmetallic particles to fine powders for ease of removal during screening.

ATTRITORS AND BALL MILLS HOW THEY WORK Robert E.

There are quite a few types of Attritors we can egorize them as dry grind Attritors, wet grind Attritors, regular speed Attritors, and high speed Attritors. A useful and simple equation describing the grinding momentum is M x V (mass x velocity), which enables us to see how the Attritor fits into the family of mills. For example, ball mills use

Optimum choice of the makeup ball sizes for maximum

For the same amount of ball charge, the number of balls in the mill decreases as the ball size increases. Thus, the S values are lower for larger balls. However, larger balls are capable of breaking large particles therefore, the size at which the S value becomes maximum, x m, increases as the ball
