Abstract

211,517. Andrews, H. May 22, 1923. Slag cements.-Lime, with or without other substances such as silica and iron ore, is mixed with molten blast furnace slag, and the mixture is fed into a rotary kiln at 1500‹ C. The waste gases from the kiln are utilized to burn limestone for the production of the lime used in the process. The clinker is ground with or without an addition of 30-50 per cent of granulated slag.
