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.
milling efficiency is a product of stress intensity and stress numbers, and the best milling efficiency is achieved by selecting grinding media size, denisty of grinding media, and mill speed to approach an optimum stress intensity and maximize the stress number. Due to Kwade´s investigations and modelling of grinding
