MATERIALS AND METHODS The general design was based on the process of allowing a strong and durable metallic object inform of hammers to beat any material that obstruct its way during operation, thereby resulting into breakage of the material which can also be referred to as size reduction in comminution operation.

In the hammer mill, a high speed impactor generates collisions with slowly moving feed. An alternative arrangement is to generate streams of high speed feed particles and have them collide with stationary surfaces. One such class of crusher is called a vertical shaft impactor (VSI). Fig. 16 shows a CAD model of one type of VSI.

Hammer Mill Working Principle. The hammermill, fundamentally, is a simple mechanism. The "orthodox" machine comprises a boxlike frame, or housing, a centrally disposed, horizontalshaft rotating element (rotor) on which the hammers are mounted, and usually a set of circumferentially arranged grates in the lower part of the housing.
