Roller mills are the most common mill used in the U.S. Corn Belt. They are more energy efficient and generally result in a more uniform particle size than hammer mills. However, hammer mills are still in use, and preferred when the feed will be pelleted or a need for greater flexibility in particle size. Because both are found across the ...
When calculating a mill 40 % charge volume is generally used. In pebble and ball mills quite often charge volumes close to 50 % are used. In a pebble mill the pebble consumption ranges from 3—15 % and the charge has to be controlled automatically to maintain uniform power consumption.
Traditionally, ball mills are used in cement industry for raw material, fuel and product grinding. Ball mills use an established technology and offer certain advantages. However, they have higher energy demands. By using an appropriate kind of the more efficient roller mill technologies – either as a replacement or in combination with ball mills – considerable energy savings can be ...

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 ... the energy to operate a hammermill or roller mill
Thus, roller milling was the traditional method of preparing cereals and fodder for on-farm consumption by livestock. Today, millers have the option of using either method, or both, and there are many factors that impact their choice.
