A hammer mill is an impact mill commonly used in pharmaceutical manufacturing for reducing particle size for a variety of drugs. Commercial grade ammonium sulfate was milled as a model powder. This salt was sieved to obtain particle size fractions with average diameters of 1.3, 0.9, and 0.72 mm which were used as feed particles.

Hammer Mill - Principle, Construction, Working, and More

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.

Pin Mill vs. Hammer Mill: A Contrast and Comparison

Pin Mills use shearing and impact methods; however, with a faster tip speed of intermeshing pins when compared to a Hammer Mill. Centrifugal force brings the particle sizes to the grinding chamber's periphery for collection or further processing. The milling process will produce particle sizes down to ultra-fine micronized sizes +/- 10 µm.
