with certain shapes and sizes. According to [6] the process of making coal briquettes is a mixture preparation of materials (drying, homogenization, addition of binding) and under pressure using mechanical devices. Coal briquettes consist of two types, namely carbonated and noncarbonated briquettes. Carbonated

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 ...

A cold coal briquetting process comprises mixing fine coal with polyvinyl alcohol and a hardening agent selected from iron oxide, phosphate rock and bauxite or combination of two or more thereof. The process permits economies in process and capital costs compared to existing briqueting processes, while still producing satisfactory briquettes.
