specific energy consumption at the same screen size hammer mill (Mani et al., 2004). They also found that stone sorghum residues required the least specific energy (Bargen, Lamb, and Kneels, 1981). As grinding machine variables, for the hammer mill thickness effect, the specific energies increased as the hammermill thickness increased.

Adequate selection of the operating parameters for a hammer mill can maximize efficiency and enhance the uniformness of the product obtained: Material to be ground: when milled, raw materials behave differently; the factors that have the greatest impact on milling properties are firmness and elasticity.An increase of moisture in the product affects these two parameters and raises them.
