Abstract

260,447. Pontoppidan, C., and Buntzen, S. Jan. 4, 1926. Cements. Portland, treating after manufacture. -In the addition of gypsum to Portland and like cements precautions are taken to prevent the conversion of the gypsum into plaster of Paris by the heat of the clinker. The precautions may consist in either (a) cooling the mill in which the clinkers and gypsum are ground together, (b) cooling the clinker before it is ground with the gypsum, or (c) adding ground gypsum to the previously ground and cooled clinker. Fig. 1 shows an apparatus for performing the third modification, comprising a water-jacketted conveyor 7 supplying the cement, a conveyor 6 supplying the gypsum, and a revolving mixing drum 1 fitted with elevating vanes 3.
