Application of size reduction theory to roller mill design and
Journal of Food Science and Technology. 2014. TLDR. Results showed that the most efficient way to increase flour yield in the eight-roller milling system is to increase the upper size limit of flour by increasing the sieve aperture, which is not followed by the deterioration of flour quality as determined by ash content.

Roller Mills
Roller mills consist of a series of rollers that are mounted on a frame, spinning on bearings. The material to be processed is fed into the roller mill, and as the rollers rotate, they crush or grind the material into smaller particles. The grind size is set by adjusting the gap between the rollers. This is done by turning a screw or lever that ...
