A ball mill is a form of grinder that is used to blend or grind materials for use. It is a cylindrical device mainly for grinding material such as iron ores, ceramic raw materials, glass, steel, etc. The ball mill works on impact and attrition principle. Its impact is the size reduction given that the balls drop from almost the top of the shell.Web

It was observed that grinding media shape (spherical, eclipsoids, cube, cylpebs, etc) can influence the performance of a tumbling mill. The media can directly affect the breakage rate, mill load behavior, power draw, and generally energy consumption. In other words, there is a strong relationship between the type of media and the …Web

The grinding media system directly determines the efficiency of grinding operation, and the granule size composition of ground products directly affects the separation index. ...

Chemical composition of typical grinding media (% wt.). Adapted from [24]. 2.1.1. Cast Iron Cast iron can be grey cast iron or white cast iron, but white cast irons are commonly used in abrasive wear appli-cations involved in the comminution process. Cast iron grinding media is one of the ancient media first used in mineral processing [25].Web

The performance of grinding media in a ball mill is also measured in terms of its wear rate. Abrasive ores such as gold and copper produce high wear rates of about 120µm/hr [74]. The wear of ...Web
