Select the optimal hammer mill or jet mill for your application by characterizing the feed material and conducting milling tests. Size reduction, or comminution, by mechanical crushing and grinding is an important unit operation in the chemical, power, mineral, metallurgical, and pharmaceutical industries.
the grains enter the hammer mill, it is pulverized by a combination of hammer blows, particle on particle contact and impact with the walls of the hammer mill. The material remains in the grinding chamber until it is able to pass through the screen covering the discharge area 
Hammer mills work on the principle that most materials will crush, shatter, or pulverize upon impact. Material is fed into the mill's chamber through the feed chute, typically by gravity, where it is struck by ganged hammers attached to a shaft that rotates at high speed inside the mill's grinding chamber.

A hammer mill, hammer forge or hammer works was a workshop in the pre-industrial era that was typically used to manufacture semi-finished, wrought iron products or, sometimes, finished agricultural or mining tools, or military weapons.
Hammer milling parameters such as screen size, blade selection and rotor speed can be optimized for each application, depending on the equipment used. The typical particle sizes that can be achieved with hammer mills is a D 50 between 150 μm and 600 μm. Hammer mills tend to yield less than 25% of particles below 150 μm.
The hammer mill was designed and constructed from locally available materials for grinding grain particles such as maize, millet, guinea corn and other coarse materials of cassava tuber, yam tuber, beans, etc. into small size enough to pass through the holes of the cylindrical sieve positioned beneath the hammer assembly.
