Reducing the screen size will thus help to reduce particle size distribution of the final product but it will come to the expense of the mill capacity. Drive A hammer mill drive must be equipped with a frequency converter in order to be able to control the speed and thus adjust the capacity and resulting fineness of the materials.

As the size of the screen opening impacts the size of particles prothe particles such that decreasing the size of the screen openings increases the energy consumed in the process [2]. Furthermore, an increase in material moisture also increases the energy consumed to size reduce the material [2]. In a study conducted by Yancey, grinding et al.

Screen Design The amount of open area in a hammer mill screen determines the particle size and grinding efficiency. The screen must be designed to maintain its integrity and provide the greatest amount of open area. Screen openings (holes) that are aligned in a 60degree staggered pattern optimise open area while maintaining screen strength.

Reducing the hammer mill screen from 3mm down to 2mm reduced average particle size in all three grains (wheat: 639 and 552 µm; sorghum: 654 and 602 µm; barley: 676 and 639 µm respectively for the 3mm and 2mm screens). Durability of the pellet was superior when sorghum was excluded from the diet, regardless of hammer mill screen size.

 · The screen found at the end of the mills' discharge opening is usually made from steel. The screen includes holes or perforations in a wide range of sizes. The size of the holes or openings determines the screen size required for electronic scrap. Based on the productivity goals, the screen size can be in inches, millimeters, microns or US mesh.

Grinding is a random process and is subjected to the laws of probability. Grinding steps: i. Primary (Coarse) grinding (generally a rod mill is used)(Feed size as large as 50 mm, product size as fine as 300 microns)(1000 microns = 1 mm) ii. Secondary (Fine) grinding (generally a ball mill is used)(Feed size as large as mm,
