METHOD FOR PRODUCTION OF PORTLAND CEMENT KLINKER

摘要

A method for production of portland cement klinker provides for preparation of a raw-material mixture comprising, by weight, 55.2-62.0 per cent of finely-ground limestone, 0.8-11.0 per cent of finely-ground mineral admixtures and 44-27 per cent of phosphorous slag in the form of grains not exceeding 9 mm in size. The thus prepared and thoroughly blended raw-material mixture is subjected to roasting. The portland cement klinker brick obtained is subjected to forced cooling.
