The design and placement of hammers is determined by operating parameters such as rotor speed, motor horsepower, and open area in the screen. Optimal ham-mer design and placement will provide maximum contact with the feed ingredient. Mills in which the rotor speed is approximately 1,800 rpm, hammers should be about 10 inches (≈ 25 cm) long,

The work index Wi can be determined from plant operations and from laboratory ball mill grindability, rod mill grindability, and impact crushing tests. The laboratory test results are used to check the efficiency of commercial operations and to compute the proper machine sizes for new installations.

Hammer mills work on the principle that most materials will crush, shatter or pulverize upon impact. The Process: • Material is fed into the mill's chamber through the feed chute, typically by gravity. • The material is struck by ganged hammers (generally rectangular pieces of hardened steel) which are attached to

before mounting the Hammer mill. The following materials are to be used when mounting the Hammer mill: o Correct Electric cable for hammer mill. If three phase, a 3 core plus earth or 4 core cable is required. o Tools: Drilling machine, drill sizes as required for mounting between 12mm and 20mm.

mills have intrinsic cooling due to compressed air expan-sion in the body of the mill. With the help of sweeping air, hammer mills may also be able to process materials with low melting points for coarse grinding applications. Explosibility. The risk of dust explosions must be taken into account when a material is ground very fine in a milling

(Retsch Cross Beater Hammer Mill Sk1, Retsch, Haan, Germany) equipped with a 1 mm mesh.

hitting the sieve with a hammer will damage the sieve. The final total of the weights retained on each sieve should be within 0.3% of the original weight of the sample prior to grading. Particles larger than 3 in. (75 mm) should be hand-sieved. When passing large stones through sieves, do not force the aggregate through the sieve openings.

•Heat buildup during milling is more, therefore, product degradation is possible. •Hammer mills cannot be employed to mill sticky, fibrous and hard materials. •The screens may get clogged. Wearing of mill and screen is more with abrasive materials.

Hammer mills use large rotating drums with protruding metal bars (i.e., hammers) that impact the material at high veloc - ity to shatter and tear material particles. Typically, the metal bars swing freely from the drum, but fixed hammers are also common in hammer mill designs. Hammer mills are recognized as technology capable
