which reduce rock, grains or similarly hard objects to a predetermined size through a perforated screen, hammer mills can be used for grinding grain into fine flour or into coarse meal for animal feed production. This project is focused on the design, development, and testing of a hammer mill that has a small scale production capability.
History Waterpowered trip hammer mills were created in 488 AD by the medieval Chinese mathematician and engineer Zu Chongzhi which was inspected by Emperor Wu of Southern Qi (r. 482493 AD). [1] [2] [3] The waterpowered trip hammer mills were powered by minor hill flowing stream that was connected to a large river beneath the high banks. [4]
Hammer mills are widely used for material size reduction in food and feed industries. In this paper, a new hammer mill with separate sieving device has been designed and fabricated, in which the socalled materialcirculation layer can not be formed and material being ground passes through the sieve by rotor throwing and air blowing without direct rubbing with the sieve.
The machine is of hammer mill type. In this case, there is hammerlike projection mounted on a shaft. The hammer revolves at high speed and grinds the materials fed into pieces by beating. Moreover, the machine can mill only the dry materials. The machine is incorporated with a detachable sieving mechanism to ensure fineness of cereal grain ground.

Hammer Mill HM 200 Rugged design meets high final fineness. Hammer mills are used for crushing, pulverizing and deagglomeration of mediumhard, hard, brittle, tough and fibrous samples. The rugged RETSCH Hammer Mill HM 200 accepts large feed sizes up to 100 mm which can be reduced to less than mm, depending on the sample properties.
The attrition zone is the area created between the top rotor and bottom rotor of a dual stage hammer mill. Materials pass through the initial mill and screen arrangement and are then directed toward the secondary mill chamber. Before reaching the second rotor, particletoparticle impact in the attrition zone creates additional opportunities ...
