METHOD FOR MAKING BRIQUETTES Russian patent published in 2003 - IPC

FIELD: processes for making briquettes of fine-grain polydispersed materials. SUBSTANCE: method comprises steps of mixing fine-grain polydispersed material with liquid glass at temperature 50 -90 C; briquetting mixture under pressure; feeding for mixing heated fine-grain polydispersed material and heated or non-heated liquid glass; after mixing agitating prepared mixture at condition providing evaporation of moisture from its surface and cooling mixture by indirect heat exchange until temperature no less than 40 C. Processes of mixing, agitation at cooling mixture and at evaporating moisture from its surface and briquetting are realized continuously. EFFECT: enhanced strength of made briquettes. 9 cl, 2 tbl
