Hammer mills consist of a series of hammers suspended from a central shaft and enclosed within a rigid metal casing. Particle size reduction in a hammer mill occurs as a result of the impaction/attrition between the rapidly moving hammers and relatively slowmoving particles (Koch, 2002; Van der Poel et al., 2018). A screen fitted in the ...

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.

II. WORKING OF HAMMER MILL MACHINE When feed is delivered to the hammer mill crusher, it is prepared for cyclone furnace firing by being crushed into 1/4 inch or smaller size feed. Feed enters from the top and is violently thrown against the breaker blocks by the hammers. The final crushing is done between the hammer faces and the screen bars.
