Cement is so fine that 1 pound of cement contains 150 billion grains. The cement is now ready for transport to ready-mix concrete companies to be used in a variety of construction projects. Although the dry process is the most modern and popular way to manufacture cement, some kilns in the United States use a wet process.
The use of alternative fuels in cement manufacturing, therefore do not only afford considerable energy cost reduction, but they also have significant ecological benefits of conserving non-renewable resources, the reduction of waste disposal requirements and reduction of emissions.

So, what exactly is petcoke, and what is it used for? Petcoke is a byproduct created when bitumen found in tar sands, like those in Alberta, Canada, is refined into crude oil. Bitumen contains a higher number of carbon atoms than regular oil and it's these atoms, extracted from large hydrocarbon molecules using heat, that go on to form petcoke.
Jun 12, 2013· re Troubles in using petcoke. Hello Sidhant, I suspect your dusty conditions and kiln inlet ring are the result of very high sulphur recirculation as a consequence of using petcoke. Even though you may have no CO in the kiln inlet, the large amount of SO3 introduced by the petcoke may not be properly balanced by alkalis in the kiln feed.
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. NOTE:
