Influence of sieve openings size for hammer mills on the degree of shredding and grinding energy consumption for maize.

Grinding is the operation to reduce the geometrical dimensions of the particles by destroying their physical integrity, as a result of mechanical action on the material. Grinding operation efficiency consist in the conversion with minimum power consumption and maximum productivity gave one solid material in a powdery or granular product size and shape required. In this paper we determined that using a sieve with greater opening can reduce the energy consumption by 32%.
