The Cement Production Process. ... and from wet long and Lepol kilns to suspension preheater with precalciner kilns. ... Raw mix was introduced into the kiln as a slurry and all of the functions from evaporation of moisture to clinkering were performed in the kiln. Chains were used to efficiently transfer heat from the combustion gases to the ...
Cyclone preheater is one of the core equipment in the new dry cement production process, which is responsible for many functions such as gas-solid dispersion, material heating, gas-solid separation, material transportation and some physical and chemical reactions.. Separation efficiency and resistance loss are two main performance indexes to be considered in the design of cyclone preheater.
As the core equipment of dry method cement production line, cyclone preheater use suspension preheating to preheat and partly decompose the cementraw mix, shorten the length of rotary kiln, fully mix raw mix and hot air in the kiln, increase heat exchange rate, which promote the efficiency of rotary kiln plant and reduce the energy consumption.

Greater Detail: Cement Plant Operations Handbook, Pages 39-45 Crewmen's Guide, Clinker Production, Pre-calciner, Page 32 (82) Preheaters In the 1930s, significantly, in Germany, the first attempts were made to redesign the kiln system to minimize waste of fuel[5]. This led to two significant developments: the grate preheater the gas-suspension preheater.
Cement kilns are used for the pyroprocessing stage of manufacture of Portland and other types of hydraulic cement, in which calcium carbonate reacts with silica-bearing minerals to form a mixture of calcium silicates.Over a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity usually defines the capacity of the cement plant.
