media balls or hardened steel media balls of 2 mm diameters were utilized with balltopowder ratios of 1:1 (vol.%) during initial milling. Manipulating one step of the experimental procedure produced three coating types, Al 2 O 3, Al 2 O 3 /Fe 3 O 4, and Fe 3 O 4. Alumina coated iron powders were produced by milling Fe powder with Al 2 O 3

 · In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize "just in case". Well, this safety factor can cost you much in recovery and/or mill liner wear and tear.

Metal mixes. Mechanical alloying is akin to metal powder processing, where metals may be mixed to produce superalloys. Mechanical alloying occurs in three steps. First, the alloy materials are combined in a ball mill and ground to a fine powder. A hot isostatic pressing (HIP) process is then applied to simultaneously compress and sinter the powder.
