This review aims to help the cement industry to select the best method for improving energy efficiency and emission reduction. Various energy conservation and emission reduction approaches are …
view more202111 · There are three types of cement manufacturing processes - wet, semi-dry and dry processes. In the wet/semi-dry process, the raw materials are produced by mixing limestone and water (called slurry) and blended with soft clay. In dry process technology, crushed limestone and raw materials are ground and mixed without addition of water.

The basis of the study was a 5-stage preheater with precalciner dry process cement plant with a cement output of 1 Mt/y located in NE Scotland, UK. Process Flow Diagrams (PFDs) and heat and mass balance calculations for both options were …
view moreCement comprises about 10% of a typical concrete mix but accounts for 92% of its energy demand. Cement production requires the pyroprocessing of large quantities of raw materials in large kilns at high and sustained temperatures to produce clinker. An average of almost 5 million Btus is used per tonne of clinker.
