To transport and utilize fine waste coal, it is required to form larger-sized coal briquetttes. An important element of a fine coal briquetting process is mixture preparation (drying, homogenization, binder addition) and molding under pressure using a coal briquette roller press.
 
Coal is the primary raw material, and is used to produce moe than 60% of the total electricity supply. Fine coal waste, as a by-product of the coal processing is cumbersome to manage. Significant amounts of fine coal waste are stored in landfills or underground. Damp and low-calorie coal sediment materials are particularly difficult to load, to transport and combust. Physical and physicochemical methods can be used to obtain enriched fuel suitable for utilization.
