feed hammer mill design and structure
The design and placement of hammers is determined by operating parameters such as rotor speed, motor horsepower, and open area in the screen. Optimal
feed hammer mill design and placement will provide maximum contact with the feed ingredient. feed hammer mills in which the rotor speed is approximately 1,800 rpm, should be using hammers which are around 25cm  long, 6.35cm  wide, and 6.4mm  thick. For a rotor speed of about 3,600 rpm, hammers should be 15 to 20 cm  long, 5 cm  wide, and 6.4 mm  thick.
The number of hammers used for a feed hammer mill of 1,800 rpm, should be 1 for every 2.5 to 3.5 horsepower, and for 3,600 rpm, one for every 1 to 2 horsepower. Hammers should be balanced and arranged on the rods so that they do not trail one another. The distance between hammer and screen should be 12 to 14 mm for size reduction of cereal grains.
feed hammer mill Screen Design
The amount of open area in a  
diesel 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 60-degree staggered pattern optimize open area while maintaining screen strength. This method will result in a 40 percent open area using 3.2 mm (1/8 inch) holes aligned on 4.8 mm (3/16 inch) centers.
Feed producers need to pay particular attention to the ratio of open screen area to horsepower. Recommended ratio for grains would be 55 cm2 (~ 8-9 inches square) per horsepower (Bliss, 1990). Not enough open area per horsepower results in the generation of heat. When the heat generated exceeds 44C to 46C (120-125F), capacity may be decreased as much as 50 percent.
