Economics of Grinding for Pelleted Feeds original

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,
