6. HAMMER MILL MECHANISM Hammer mills reduce the particle size of materials by impacting a slow moving target, such as a cereal grain, with a rapidly moving transfer of energy resulting from the collision fractures the grain into many pieces. Since impact is the primary force used in a Hammer mill to reduce the size of the particles, so, whatever increases the chance of a collision ...

Plastic materials: Synthetic gums, waxes and resins become soft and plastic during low melting substances should be chilled (made cold) before milling. These types of materials are milled by using hammer mill and fluid energy mill. Hygroscopic materials: Hygroscopic materials absorbs moisture rapidly hence they must be comminuted inside a closed equipment like ballmill.
