#### Hammer mill: parameters that affects grinding

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.Grinding Parameters and their Effects on the Quality of,using a hammer mill with two hammer thickness scenarios: 3.2 and 6.4 mm. The average specific energy for thin hammer tests was 10.2 kW h/ Mg, which was 13.6% less than that of the thick hammer (11.8 kW h/ Mg). The grinding rate was higher for the thin hammer configuration [8,9] reported that the specific grinding energy of uncrushed kernels

#### Back to Basics Hammer Milling and Jet Milling Fundamentals

A hammer mill is typically good for grinding softer materials with Mohs hard-ness ranging from 1 to 5, while a jet mill can grind materials with Mohs hardness as high as 10. High hardness materi-als become very abrasive; therefore, they are not suitable for high-speed hammer mills. In a typical jet mill, grindingImprovement on the Design,Construction and Testing of,hammer tips as given by the equation A common range of tip speed seen in hammer mills is commonly in the 5kg maize was fed into the hopper and the hammer mill was switched on.
