Clinker Production - an overview | ScienceDirect Topics

Cement manufacturing has several opportunities for WHR, specifically in the process step where the clinker material is produced. For clinker production, a mixture of clay, limestone, and sand is heated to temperatures near 1500°C. The kiln and clinker cooler have hot exhaust streams where waste heat could be recovered.

Cement Clinker Quality Control During Clinker Production ...

During normal production process, the clinker is always calcined in a fixed temperature range. According to the fluctuation of raw meal composition, the calcination temperature of clinker is generally between 1350℃ and 1450℃. If the temperature in the kiln is too low, it is easy to produce underfired clinker.

to produce clinker. Clinker, an intermediate product, is mixed with a small amount of gypsum and/or anhydrite to make Portland cement. Some varieties of masonry cement require additional lime, and thus may additional CO 2 emissions. CO 2 might also be emitted from cement kiln dust (CKD) that is not recycled to the production process.
