What is a ball mill? A ball mill is a size reduction or milling equipment which uses two grinding mechanisms, namely, impact and shear. 1 Unlike other size reduction equipment, such as breakers and jaw crushers, ball mills are capable of producing powders and particulate materials of mean particle sizes within the 750 to 50 micron (µm) range.. Ball mills serve both dry and wet milling ...
Factors affecting size reduction Abrasiveness: Abrasiveness is a property of hard materials (particularly those of mineral origin). It may limit the type of machinery that can be used. During the grinding of some very abrasive substances the final powder may be contaminated with more than percent of metal worn from the grinding mill
Ball mill: Ball mill is a type of crusher, is a cylindrical device used to grind or mix materials like ores, chemicals, ceramics and paints. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium.

14. High ball milling: Ball milling process where a powder mixture placed in the ball mill is subjected to highenergy collision from the balls. This process was developed by Benjamin and his coworkers at the International Nickel Company in the late of 1960. It was found that this method, termed mechanical alloying, could successfully produce fine, uniform dispersions of oxide particles (Al2O3 ...
