Economics of Grinding for Pelleted Feeds In the feed manufacturing industry, particle size reduction (grinding) is second only to extrusion processes (pelleting, expanders, extruders) in terms of total energy consumption. To achieve a finer grind (smaller finished particle size), energy and maintenance costs increase and,

Grinding mills can process an array of materials and can operate through many different methods. In the past, windmills, waterwheels and animals powered grinding mills, but the grinding mills on which industry relies today are much more powerful and are capable of performing much more demanding tasks.

Media sizes for coarse grinding in heavy-duty ball mills range from about 80 mm maximum to 20 mm and for medium to fine grinding mill on down at about a minimum of 8 mm. Below about 16 mm, removal of the ground mixture becomes increasingly difficult and the practical media size limit is around 12 mm. Grinding capabilities of all these small ...
