A Review on Pyroprocessing Techniques for Selected Wastes Used for ...

The remainder of the emissions is generated from fuel combustion. As calcination is at least 90% completed when the raw meal is fed into the rotary kiln, the PC technique allows a considerable increase in the clinker capacity. The average capacity of new European plants ranges from 3000 to 5000 tons of clinker per day.
