Analysis of energy requirement for hemp fibre

Hammer mills have low energy efficiency (Lobo 2002). For this reason, many researchers have studied the energy requirements of hammer mills. Those studies focused on size reduction of different materials, and not on fibre decortication. Normally, specific energy is used to assess the energy consumption of hammer mills. Specific

468 MJ/Mg for both hammer and knife mills. Hammer mill required more energy (414 MJ/Mg) than a knife mill (180 MJ/Mg) for 3.2 mm particle size. They observed that agricultural straw and corn stover required 6 to 36% of the effective specific energy required for wood. Vigneault et al. [21] observed a 13.6% saving in total specific energy

Hammer mills: hammermills Feed Mill Machinery Glossary

This excessive size reduction is counterproductive. Energy is wasted in the production of heat, throughput is restricted, and particles become too small. Most newer hammermills are equipped with an air-assist system that draws air into the hammer mill with the product to be ground.

COMPARISON OF ENERGY EFFICIENCY BETWEEN A ROLLER MILL
