Ball mill
A cylindrical grinder used to grind, or mill, raw materials for use in ceramic bodies or glazes. Size reduction of the feed materials is achieved by a combination of impact and attrition resulting from the tumbling of hard media, such as pebbles, inside the mill during the rotation of the mill. Ceramic raw materials which are commonly milled include quartz, feldspar and calcined alumina. Ball mills can also be used to mix ceramic bodies.[1]
