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 ...

The Model C is a relatively highcapacity compact mill. The rotor diameter is 18" and the grinding chamber is 14" wide. Recommended for use with main drive motors ranging from 30 to 75 HP, depending on the material being ground. The cover is hinged with a handle and 4 swing bolts which allow for quick access to the grinding chamber.

The working principle of the hammer mill is simple to understand. The principle is illustrated in Fig. 1 (a). It only requires choosing an appropriate motor, crushing hammers/knives and material to be crushed. It operates on the principle of impact between rapidly moving hammers mounted on the rotor and the stationary powder bed.
