Aug 20, 2015 Cement manufacturing is a complex process that begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called raw meal, which is then heated to a sintering temperature as high as 1450 °C in a cement kiln. The clinker is ground to a fine powder in a cement mill and mixed with gypsum to create
The temperatures employed for the production of hydraulic gypsum cements through dehydration of rock gypsum distinguish the manufactur35 ing process from that used in making the socalled Keene's cement from hydrated gypsum as according to U. S. Patent 1,993,238 the manufacture of Keene's cement is preferably carried out within a temperature
Apr 14, 2016 MANUFACTURING PROCESS OFCALCINED GYPSUM The raw material gypsum is sorted and washed with water for removal of sand and other impurities. The lumps thus obtained are then dried and powdered in pulverizer. The dried gypsum powder is calcined in a rotary drum calciner at a temperature of 160ºC to 180ºC. The process of calcination is done
