Raw material such as limestone, clay and sand and other aggregates are mined in quarries. They are ground and milled. The raw mix is fired in a rotary furnace at approx. 1,450 degrees Celsius to make clinker brick. In another mill, gypsum is added to form the end product cement. The pollutants released in this branch of industry is considerable.
CEMENT 6 SikaGrind® FOR VERTICAL ROLLER MILLS SikaGrind® FOR SLAG CEMENT Granulated blastfurnace slag (GBFS or GBS) is a byproduct of the steel industry. By water quenching of the molten iron slag a very dense and glassy product with an appearance like coarse sand is generated.
4 Due to the interaction of raw materials and kiln gases, rotary kiln systems have inherent SO2 removal efficiencies ranging between 4099% of the sulfur input to the system. The literature suggests that 5070% of the remaining SO2 will be removed from exhaust gases when passed through an inline raw mill
Manufacturing the cement kiln. Most Portland cement is made in a rotary kiln. Basically, this is a long cylinder rotating about its axis once every minute or two. The axis is inclined at a slight angle, the end with the burner being lower.
A rawmill is the equipment used to grind raw materials into "rawmix" during the manufacture of cement. Rawmix is then fed to a cement kiln, which transforms it into clinker, which is then ground to make cement in the cement mill. The rawmilling stage of the process effectively defines the chemistry (and therefore physical properties) of the
