Abstract

785,335. Making cement. SMIDTH & CO., AKTIESELSKAB, F. L. May 27, 1955, No. 15434/55. Class 22. A method of making cement comprises determining the amount of solids in dewatered slurry in a continuous flow thickener by supplying liquid slowly to an open-ended duct 3 which passes downwards into the slurry 2 and measuring the heights of the surfaces of the liquid within the duct and of the slurry outside the duct, and to keep that amount constant the slurry is fed from the thickener to a cement burning kiln at a rate controlled in accordance with the amount determined. If the amounts of solids at a plurality of levels is required a corresponding plurality of ducts passes into the slurry to these levels.
