Ball mill, also known as tumbling or pebble mill is milling equipment that encompasses cylindercontaining balls and is mounted on a metallic frame that can be rotated along with a longitudinal axis. The large ball tends to break down coarse feed materials and the small ball mill to form fine products by reducing void spaces.
The mill is used for applications in geology, chemistry, mineralogy and materials science, quality control as well as RD. Because of its unique grinding motion, the XRDMill McCrone is particularly effective for this analytical method: The 48 cylindrical grinding elements grind the samples gently via friction.
Steel Ball Mills Lined Ball Mills. Particle size reduction of materials in a ball mill with the presence of metallic balls or other media dates back to the late 1800's.

Other aggregate abrasion testing was done in 1996. At that time, ODOT sent 14 aggregate samples to the Alaska Department of Transportation for Nordic Ball Mill testing. The Nordic Ball Mill method simulates the abrasive action of traffic on coarse aggregates used in the pavement surface layer.
A ball mill can divide into 2 types, wet ball mill, and dry ball mill. Ball mill is a mineral processing machine for milling the materials into powders after they are crushed. It is widely applied to the production of cement, silicate products, building materials, fireproof materials, fertilizers, glass, ceramics as well as nonferrous and ...
