1. Introduction. Compared to conventional steel media, ceramic balls have a lower specific gravity and superior wear resistance [1].Ceramic balls were initially used primarily in the IsaMill because they could provide fast stirring speed while maintaining high kinetic energy (E = mv 2) despite their low specific gravity [2].According to Kwade's …

The working principle of a ball mill is based on the impact and attrition between the balls and the grinding media. As the mill rotates, the grinding media (usually steel or ceramic balls) are lifted to a certain height and then allowed to fall freely, causing the materials to be reduced in size by the impact and abrasive forces generated ...

If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or 1.5 times the drum diameter. Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills.
