The hammer mill is characterised by simple operation and handling. The machine works according to the principle of crushing by multiple impact, so that the most effective crushing takes place by the direct impact of the hammer mill beater on the product. The circumferential speed of the beater tip is approx. 360 km/h.

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.
