For example, in the 1980s, the largest operating ball mill was 5.5 m in diameter by 7.3 m in length driven by a 4 MW motor. Today the largest ball mills in operation are over 8 m in diameter utilizing gearless (wrap-around) motors with power output of more than 16 MW.
1. Cylindrical Shell: The ball mill consists of a hollow cylindrical shell that rotates about its axis. The shell is usually made of steel, stainless steel, or rubber. 2. Liners: An abrasion-resistant material such as manganese steel or rubber typically lines the inner surface of the cylindrical shell to protect it from wear due to the grinding action.

Table 5 illustrates results, starting with 5.5 x 6.4 m and 5.5 x 8.5 m (18 x 21 ft; 18 x 28 ft) mills and reducing velocities from the overload value progressively to 60 percent of that value. It is notable that the largest diameter required is 6.8 m (22.5 ft), – much less than those current in North America for larger SAG or autogenous mills.
Alloys can be prepared by using different equipments such as, attritor, planetary mill or horizontal ball mill. The working principle for all these techniques is same. During alloy formation using ball-mill, two processes simultaneously occur: (a) fracturing, and (b) cold welding of powders. Thus, it becomes imperative to create a balance ...
Ball end mills, or ball nose end mills, are used for drilling shallow holes, slotting a channel where a flat bottom is not required or most commonly used to produce multi-dimensional contours in molds or dies. The design of ball end mills forms a hemispherical cutting action identical to the diameter of the tool.
