MOTORIZED GRAIN CRUSHER

The project titled “Design and Fabrication of a Grain Crusher” was aimed at developing a small-scale, electrically powered machine for crushing and grinding grains such as maize, millet, and sorghum into finer particles for easy processing. The objectives were to design a hammer mill-type crusher suitable for local use, ensure ease of maintenance, minimize power consumption, from locally sourced materials. The methodology involved conceptual design, material selection, component fabrication, and
assembly of the crushing unit, hopper, frame, and power transmission system. Key design parameters such as shaft diameter, pulley ratio, hammer dimensions, and motor power were determined using standard mechanical design equations. erformance evaluation was conducted through test runs using maize to assess crushing efficiency and particle size distribution.
