METHOD OF BRIQUETTING WET FINE GRAINS OF COAL AND SLUDGES Russian patent published in 2008 - IPC C10L5/14 

FIELD: chemistry.

SUBSTANCE: invention pertains to the technology of briquetting carbon fuel, in particular, to the method of obtaining fuel briquettes and can be used in the coal, metallurgy, energy and other industries. The method involves mixing a binding substance with fine grained coal, briquetting of the mixture and drying of the briquettes. The method is unique in that, slurry coal is added into the mixture of the binding substance with the fine grained coal, while the binding substance, depending on the technological requirements for the briquettes, is in the form of a water solution of latex CKMC-30 APK, water solution of bustilat, water solution of PVA glue, water solution of "КМЦ-55" or "КМЦ-75" glue. Partial drying of briquettes is due to the heat released during briquetting by pressing.

EFFECT: lower expenses and increased productivity.
