It has been established that normal emulsions can be prepared from the BN-III and BN-IV bitumens in slow vane mixers and be used as binders in the briquetting of solid fuels.
Normal bitumen emulsions coat well the surface of cold and wet coal particles, which eliminates the need of thermal drying, and cooling of the charge and briquets.
Mixing of the coal with the emulsion and the subsequent briquetting of the charge is done without heating.
The strength of the briquets manufactured with the new binder met the GOST specification immediately after the briquets left the press.
Cold briquetting of coal and anthracite fines considerably improves the sanitary- hygienic conditions in the plant.
