Hammer Mill Principle, Construction, Working, and More. A hammer mill is an essential machine in the pharmaceutical and food processing industries. It can be used to crush, pulverize, shred, grind and reduce material to suitable sizes. In a hammer mill, swinging hammerheads are attached to a rotor that rotates at high speed inside a hard casing.

During grinding, balls themselves wear and are constantly replaced by new ones so that mill contains balls of various ages and thus of various sizes. Ball mills produce 1 to 50 ton/h power of which near about 70 to 90 percent would pass a 200 mesh screen and the energy requirement of a ball mill is about 16 kWh/t.

The tumbling mill principle is based on the impact and attrition of the grinding media against the materials to be ground. As the cylinder rotates, the grinding media falls, collides, and crushes the materials inside the cylinder. The impact of the grinding media generates heat, which can affect the quality of the final product.

Principles of Grinding. In all forms of grinding, three different interactions occur between the abrasive and the machined material. Cutting occurs where the abrasive grain is sufficiently exposed to penetrate the workpiece material and curl a chip, and sufficient clearance exists between the grain, bond and workpiece to flush the chip with coolant or throw it away by wheel action.
