What is Cement Clinker? Datis Export Group

2020-6-18  Clinker is a nodular material produced in the kilning stage during the production of cement and is used as the binder in many cement products. The lumps or nodules of clinker are usually of diameter 3-25 mm and dark grey in color. It is produced by heating limestone and clay to the point of liquefaction at about 1400°C-1500°C in the rotary kiln.

Optimal fluorite/gypsum mineralizer ratio in Portland

lems of the cement industry is that 0.73–0.99 tons of CO. 2. are emitted per ton of cement manufactured, depending on the clinker/cement ratio and other fac tors. From these data, some researchers have esti-mated that the cement industry is responsible for 5–7% of all global anthropogenic emissions (7, 8).
