[PDF] Hammer mill grinding rate and energy requirements ...

Two ham mermill hammers of different thickness were compared in a commercial feed mill using the existing equipment. Comparison of specificenergy consumption and grinding rate were done. Lifetime evaluation was attempted. The results showed that a 13.6% saving in specific energy consumption and an increase of 11.1% in grinding rate can be obtained by using a thin hammer without affecting the ...

Measurement of energy requirements for size reduction of ...

The study estimated the amount of energy required for grinding palm kernel shell and groundnut shell using laboratory hammer mill and also characterize their ground physical properties. The material type and hammer mill screen aperture significantly influenced the energy requirement for grinding the two materials. For a given screen aperture size, groundnut shell consumed more energy than palm ...

COMPARISON OF ENERGY EFFICIENCY BETWEEN A

For roller mill grinding, roll gap was the most significant factor affecting energy requirement, followed by the roll speed differential. For hammer mill grinding, screen opening size had the most significant effect. For both mills, feed rate was not significant; and energy efficiencies were about the same.
