Coal Briquette

The coal briquette made up from raw coal material that comes from Indonesia's coal mining company. Raw coal material changes to briquette in several purification stages. In each successive stage, higher pressure and heat applied to the raw material to increase the carbon content and drive out more of its sulphur and moisture content. Pure coal material then grinded to make granular shape and ready to compressed into briquettes.
