Size reduction in impact crushers occurs through particle concussion by rigid forces. The hammer crusher , also called the hammer mill, is an example of an impact crusher. In hammer crushers, hammers swing freely on a disc mounted on the main shaft within the device . As the disc rotates, the feed material is struck and crushed by descending

The hammer mill is the best known and by far the most widely used crushing device employing the impact principle of breaking and grinding stone. Thus far we have described machines which do a portion of their work by impact, but the only machine described in which this action plays an important role was the sledging roll type and particularly the Edison roll crusher and in these machines

Size reduction alone is not sufficient to obtain mono-size or narrow size range powder. Therefore, size reduction and size separation should be combined to obtain powders of desired size. The mining, ceramic materials, chemical products, pigments and pharmaceutics industries all rely on size reduction to improve performance or to meet

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 slow-moving particles (Koch, 2002; Van der Poel et al., 2018).
