Milling Media Synthesis

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.

Rod mill is similar to ball mills but it uses long rods for grinding media. Autogenous mill is a self-grinding mill which is used in breakage of larger rocks. SAG (Semi-Autogenous Grinding) mill is an autogenous mill which uses grinding balls, it is similar to ball mill but has large diameter and short length.

The materials used in this study included W–3.5Ni–1.5Fe–0.3Y 2 O 3 and W–7Ni–3Fe–0.3Y 2 O 3 (in weight percent). Both materials were produced by mechanical alloying and performed in a SPEX8000 ball mill with a speed of 1080 rpm.In order to indentify the effect of grinding media on ODS tungsten heavy alloys, milling experiments were carried out using …

The operating principle of the ball mill consists of following steps. In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls. Then, …
