May 08, 2012· Roller mills are more energy efficient than hammer mills when grinding friable materials; the advantage for corn is <5% at sizes smaller than 500 microns, becomes 25-30% at 800 microns, and increases to perhaps >80% at a size of 3000 microns (CPM, 1992). The hammer mill (Figure 4) remains the industry standard for size reduction.

The payback calculation will be

ENERGY EFFICIENCY IN FLOUR MILLS

Efficiency is important for windmills, because the entire cost is in the technology, not the source of energy, which is wind. The most significant factor determining the efficiency of windmills is the number of blades. This is because more blades capture more energy. Large windmills must use few blades due to stress on the metal.
