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 …

course or fine grinding. The output (volume) of the hammer mill is dependent upon the screen size, shaft speed (normally between 1800 to 3,600 rpm), and the configuration of the hammers. The main problem related to hammer mills is the high wearing rate of the structure and the hammers, which are usually made of cast iron.
