Design and Development of a Grass Grinding Machine

The search for energy alternatives involving locally available and renewable resources is one of the main concerns of governments, scientists and business people worldwide. This paper focuses on the design and fabrication of a grass grinding machine to facilitate grass grinding as an aid to sustainable energy from biomass in Nigeria. The work further focuses on grinding of elephant grass for generation of energy due to its availability and alternative means of energy generation to fuelwood. The elephants grass was Oven heated to 250oC, to ensure dryness, the materials for the fabricated machine was sourced locally. They include a 1hp motor, a medium carbon steel Shaft, a SPA rubber melt, a mild Steel bearing, a 255mm by 255mm mild Steel hopper at the top and 125mm by 125mm at the bottom with a thickness of 2mm, a mild steel casing, a mild steel mesh of 4mm and cast iron pulleys. The dried grass is fed into the hopper and the tilted shaft within the casing carries out the grinding and sends it to the mesh which then sieves the ground particle into the receiver for collection. Dried Grass of mass 510.1kg was fed into the hopper and in three minutes the grass was pulverized to a fine particle of mass 43kg. The ground elephant grass can further be converted into pellets and briquettes, which can be used as heating fuel to provide an alternative to wood, biogas etc.
