Size reduction in feed technology and methods for ...

Hammer mills consist of a series of hammers suspended from a central shaft and enclosed within a rigid metal casing. Particle size reduction in a hammer mill occurs as a result of the impaction/attrition between the rapidly moving hammers and relatively slow-moving particles (Koch, 2002; Van der Poel et al., 2018). A screen fitted in the ...

DEVELOPMENT AND TESTING OF A HAMMER MILL

The machine is of hammer mill type. In this case, there is hammer-like projection mounted on a shaft. The hammer revolves at high speed and grinds the materials fed into pieces by beating. Moreover, the machine can mill only the dry materials. The machine is incorporated with a detachable sieving mechanism to ensure fineness of cereal grain ground.

Shaping, Planing and Slotting Operations

The Shaper Machine tool used for shaping operation is called shaper. Designed for machining flat surfaces on small sized jobs.If the size of the job is large, then planing isused. In a shaper, the work piece is held stationary during cutting, while the tool reciprocates horizontally. the feed and depth of cut are normally provided by moving the work.
