METHOD FOR PRODUCTION OF PORTLAND CEMENT CLINKER Russian patent published in 1998 - IPC

FIELD: production of portland cement clinker. SUBSTANCE: method includes supply to furnace of raw material mixture in two flows. In so doing, raw material mixture supplied from the furnace cold end has saturation coefficient of 0.92-2.10, and raw material mixture supplied to hot zone with temperature of 550-1200 C is presented in the form of low-melting charge which consists of fuel-containing products and technogenic materials with saturation coefficient of 0.05-0.5 and melting temperature of 1100-1150 C in points of high-temperature contact of charge ingredients or products of their heat treatment. EFFECT: intensified formation of clinker.
