The Pelleting Process - CPM
In most cases where particle sizes smaller than 10/64" are desired, it has been found to be more satisfactory from the standpoint of economics to produce a 10/64" or 12/64" pellet and reduce it into the desired particle size by means of crumbling. Almost all livestock feeders agree that animals make better gains on pelleted feed than a meal ration.
