clinker making in the kiln

Cement making consists of three major process steps: raw material preparation, clinker making in the kiln, and cement making. Raw material preparation and cement making are the main electricity-consuming processes, whereas the clinker kiln uses nearly all of the fuel in a typical cement plant. Clinker production is the most energy-intensive ...

Clinker Making Industrial Efficiency

2017-9-13  The production of clinker involves the feeding of the raw meal into the kiln, where first the calcination of calcium carbonate takes place and then the resulting calcium oxide is burned at high temperatures together with silica, alumina and ferrous oxide to form clinker. Clinker making is responsible for 90% of the total energy consumption in ...

Clinker Production - an overview ScienceDirect Topics

The clinker cooler exhaust is at a temperature near 200°C and is typically used for preheating the kiln or other parts of the clinker production process. The ORC and Kalina cycles have also been considered for use to recover the waste heat from the clinker cooler. The sCO 2 cycle could also be considered for both waste heat streams.

Cement Kilns: Special Clinkers

2019-3-14  The term "special clinker" has arisen because every cement plant produces its own, idiosyncratic "general purpose" clinker for making "ordinary" Portland cement, the properties of which are defined by the type of material in their quarry, but local specialist requirements may demand relatively small quantities of clinker with different properties.
