Briquetting Process an overview | ScienceDirect Topics

The briquetting process is the conversion of agricultural waste into uniformly shaped briquettes that are easy to use, transport, and store. The idea of briquetting is using materials that are unusable, due to a lack of density, and compressing them into a solid fuel of a convenient shape that can be burned like wood or charcoal.

Utilization of Biowaste for Sustainable Production of Coal Briquettes

Figure 1 illustrates the process flow of coal briquette formation. The raw coal and biomass are first processed in separate roller crushers to reduce the size of the coal particles. The crushed raw coal and biomass are then sent for the screening process, which takes approximately 3 min to screen (200 mesh size). During this process, different ...
