Abstract: A briquette is a block of compressed coal, biomass or charcoal dust that is used as fuel to start and maintain fire. Briquetting is a mechanical compaction process for increasing the density of bulky materials. This process is used for forming fine particles into a designed shape. It can be regarded as a waste control measure in the case of production of briquettes from agricultural wastes. However, depending on the material of interest, briquetting can be used to provide fuel source as a preventive measure to many ecological problems. Briquetting is a high-pressure process which can be done at elevated temperature or at ambient temperature depending on the technology one wants to employ. Various briquetting machines have been designed, ranging from very simple types which are manually operated to more complex ones mechanically or electrically powered. Generally, briquetting operations have developed in two directions, mechanically compression (hydraulic or pistons) and worm screw pressing types. Currently available in Western India Plywood, produced sawdust briquettes have suboptimal densities, causing incomplete burn and excess smoke. Here I made Attempts to improve this technology, particularly by adjusting the screw length to diameter ratio, the screw rotation speed, feed pressure, and residence time in the extension chamber as a means of producing a higher-density, better quality briquette.
