The process of producing cement and its followon product concrete are shown schematically in fig. 9.22 22. the raw material, mainly limestone, is crushed in ball mills, passed through an electrostatic precipitator, stored, preheated, and reacted in a hightemperature rotary kiln which yields clinker.
Energy Consideration In Cement Grinding
Typically generates 25 kcal of heat per kg cement ground o mill temperature could rise to 140 ˚c and causes gypsum to dehydrate & produces false set in cement, as well as media coating which impairs grinding efficiency o typically, 0.8 m of cooling air is required to remove the heat energy consideration in cement grinding.
