Zhang et al 2017 suggested a reformation of the production process for China s cement industry through eliminating old processes and incorporating new innovative technology like dry rotary kiln process with a multi stage preheater and a cement calciner as a better substitute for shaft kiln production technology Mikulčić et al 2016
Cement industry is considered as an energy intensive industry owing to the huge amount of heat consumed in pyro process are many conventional methods around which can be applied to carry out energy targeting in a cement production plant including conceptual mathematical or even hybrid However full application of these approaches would
In the conventional cement production process CO 2 emissions primarily result from the production of clinker the main component of Portland cement [3] Specifically two main sources of CO 2 emissions exist 1 process emissions from the calcination process where limestone CaCO 3 a key component in the raw meal for clinker production decomposes into
Accurate cement production also depends on belt scale systems to monitor output and inventory or regulate product loadout as well as tramp metal detectors to protect equipment and keep the operation running smoothly The Cement Manufacturing Process flow chart sums up where in the process each type of technology is making a difference
