There are 5,800+ animal food manufacturing facilities in the U.S. producing more than 284 million tons of finished feed and pet food each year. The mill sizes vary tremendously from a small on-farm mixer to a modern, computerized system with few human operators making more than 1 million tons of feed each year for swine or poultry operations.

For this work, our objective is to identify a feed size distribution from which maximum production of the target size can be achieved. Just to shed light on the target size, the mill product is defined by three classes; m 1 the feed size, m 2 the target size (−150 + 25 µm) and m 3 being the fines (<25 µm). A detailed procedure on how to ...
