clinker proportion to produce 1 ton cement

How much clinker is required to make one ton of cement? - QuoraThose granules are the sintered output from large rotary kilns. The amount of gypsum used to prevent flash set is usually only a few percent. So (back to the question.) just a little less than a tonne of clinker gives around a tonne of Portland cement. Minerals such as calcium carbonate can be added to the clinker in the mill.clinker proportion to produce 1 ton cement,Cement Clinker Production - L'Office de l'efficacité énergétiqueIn 1998, clinker production totalled 12 million tonnes for a capacity use of 85 percent. With more than 1100 ready-mixed and other plants across the country using Portland cement to make concrete, the industry employs some 22 000 people and generates more than $3 billion in annual sales. Almost one third of Canadian.
