Abstract

Grain is not available all the year round and even when available, the preparation is usually labour intensive. The main objective of this research is to design and fabricate a hammermill machinefor processing of grain, dry plantain/cassava using available local materials. The machine consists of number of steel hammers radially and axially spaced on a shaft or rotor which rotates at a high speed in a strong housing. As the grain is fed into the mill from a feed hopper, the hammer strike it with a great force and rapidly pulverize it. The capacity of the hammering unit is 113.049kw with a milling efficiency of 85%. The machine was developed using locally sourced materials such as mild steel thick metalplate and hot rolled steel.

Key words: Hammer mill, Pulverize, Grain Machine, locally sourced materials.
