Design and FEM Analysis of a Feed Mixer Machine

An animal feed mixing machine was designed, fabricated, and tested to enhance feed production efficiency. The machine is capable of handling 50 kg of feed, ensuring proper mixing with a high-power motor within minutes. It features a simple mechanism, integrating a chopper on the same shaft as the mixer, driven by a single 2HP motor using a V-belt drive. The machine reduces time, cost, and manpower, making it suitable for large-scale feed production. Constructed with a rectangular mild steel chamber with a semi-circular lower section (15-inch diameter), the design prevents feed spillage. The 28 mm shaft, equipped with mixing blades, ensures uniform distribution of feed components such as rice powder, wheat powder, maize bran, and sunflower cake. Additionally, cutting blades allow simultaneous grass processing. This efficient, cost-effective solution benefits the feed and food industries, reducing manual labor and optimizing production, particularly in countries like Ghana, Nigeria, Tanzania, and India.
