The simplest way to describe the concept of size reduction is to look at the industrial hammer mill model: Hammer mills operate on the basic principle that most materials will crush, shatter or pulverize upon impact. This is accomplished by a simple four step process: Material is fed into the mill, typically by gravity.

Hammer mill works on the principle of impact for size reduction of materials. Impact is offered to the feed by the sets of swing hammers which are arranged on a rotor disk. Construction of Hammer Mill It consists of a casing in which a horizontal shaft is present (see Figure 1). A high speed rotor disk is attached to this horizontal shaft.

Working Principle: A hammer mill operates on the principle of impact and attrition. It consists of a rapidly rotating rotor with swinging hammers that strike and break the material. The material is fed into the mill from the top and is subjected to the highspeed impact of the hammers. As a result, the particles are shattered into smaller pieces.

REDUCTION Size reduction is the operation carried out for reducing the size of bigger particles into smaller one of desired shapes size with the help of external forces. Comminution is another term used for size reduction. The row materiel is generally present in the large size which cannot be used by the industries so, the materiel needs to be converted into smaller particle or powder.

where E is the energy per unit mass required for the production of a new surface by reduction, K is Rittinger's constant and is determined for a particular piece of equipment and material, x 1 is the average initial feed size, and x 2 is the average final product size. Rittinger's law has been found to hold better for fine grinding, where a large increase in surface results.
