Guidelines for Particle Size on Swine Operations

Particle size is an area where producers can significantly improve feed efficiency and lower feed cost per kg of gain. Research at Kansas State University has indicated that, for corn-based diets ranging in particle size from 1200 to 400 microns, there is a 1 to 1.5% improvement in feed efficiency for every 100 micron reduction in average particle size.

Rod mills, how they function - Mine Engineer.Com

Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of 3000 to 270 mm (–4 to –35 mesh). Grinding action is by line contact between the rods extending the length of the mill. Rods tumble and spin in roughly parallel alignment simulating a series of roll crushers.
