FIELD: technological processes.
SUBSTANCE: stock is poured into conic matrix portion by portion. Then the stock is squeezed; resulting briquet is pushed through conic matrix by one move of extrusion stem with pressing disk. Before the final move of extrusion stem, working surface of pressing disk is covered with one coat of anti-adhesive substance. As such, 30-40% aqueous emulsion of chalk is used.
EFFECT: opportunity is provided to produce briquets of given height using multipurpose pressing equipment and without adding harmful substances to chemical composition of the stock.
