Hammer Mill Application Focus: Grinding Grains for Animal

Mar 29, 2013· The secondary factor in determining finished particle size if the speed of the hammer mill. When the rotor spins, the hammers flail out and impact the material with great severity causing it to break down. As a result, the higher the rotor speed, the greater the number of hammer mill blows, and thus a finer end product.

Hammer mills: hammermills Feed Mill Machinery Glossary

Hammer mills in which the rotor speed is approximately 1,800 rpm, should be using hammers which are around 25cm (~ 10 inches) long, 6.35cm (~2.5 inches) wide, and 6.4mm (0.25 inches) thick. For a rotor speed of about 3,600 rpm, hammers should be 15 to 20 cm (~ 6-8 inches long, 5 cm (~ 2 inches) wide, and 6.4 mm (0.25 inches) thick.

Hammer mill: parameters that affects grinding

When deciding the fan size, we should keep in mind that a hammer mill has a resistance of about 10-15 m bar. A reduction in the air flow rate leads to a reduction in mill capacity, finer product, higher specific energy consumption, greater heating during milling, greater wear, greater dust formation.
