Solids | Choose the Right Grinding Mill
There are many different types of grinding mills (Table 1). Some devices, such as ball mills, are more suitable for coarse materials. These mills use "large" media, ranging in size from 20 mm in diameter and up, to produce material from about ten microns to mesh sizes. Attrition mills are more appropriate for "mid-range" size particles.
