Transversal rolling of balls from the round billet is economical. It differs from other methods due to the possibility to produce grinding balls on the uninterrupted automated aggregates, which allows 2 to 8 times to increase the output and 10-15% to reduce the consumption of metal. The process involves the following stages:
Grinding Balls. Steel balls ranging from ¾ to 5 in. in diameter are used. Rods range from 1½ to 4 in. in diameter and should be 3 to 4 in. shorter than the inside mill length. Tube mills are usually fed balls smaller than 2 in., whereas 4- or 5-in. balls are more commonly used for ball-mill grinding.
Whenever two grinding balls collide, a small amount of powder is trapped in between them. Typically, around 1000 particles with an aggregate weight of about 0.2 mg are trapped during each collision (White, 1979). ... Mechanical milling of aluminum powder using planetary ball milling process a) ...
(a)ball-bearings are formed into initial round shape by a forging process; this is followed by a grinding process in a specially formed grinding die to get extremely good diameter control (≤ 15µm). (b) Knives are made from forged steel; the steel is then hardened; finally, a grinding operation is used to give a sharp cutting edge.

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles and stainless steel balls.
The grinding action employs much greater stress on the material than in a ball mill, and is therefore more efficient. Energy consumption is typically half that of a ball mill. However, the narrowness of the particle size distribution of the cement is problematic, and the process …
