Roller Mills vs Hammer Mills - Which Is Best? | Automatic ...

A roller mill can efficiently break down grain for livestock feed. Energy efficiency is especially pronounced in electric grain roller mills.In some situations, roller mills use 85% less energy to process grain than hammer mills. In the most common processing situations, though, the energy savings are likely 30-50%.

COMPARISON OF ENERGY EFFICIENCY BETWEEN A ROLLER MILL …

AIt is generally believed that roller mills utilize energy more efficiently than hammer mills (Silver, 1931; Puckett and Daum, 1968; Appel, 1987). To verify this, a completely randomized factorial experimental design (CRD) with two replications was constructed: a total of 72 grinding tests was conducted to compare the energy efficiency between a roller mill and a hammer mill.
