Coal in the cement industry

2012-11-8  Cement manufacturing consists of raw meal grinding, blending, pre calcining, clinker burning and cement grinding. Limestone, CaO, SiO2, Al2O3 and Fe2O3 are crushed and milled into a raw meal. This is blended and preheated in a preheater cyclone. Preheating of raw feed increases the energy efficiency of the kiln as the material is 20-40% calcined at the point of entry into the kiln. At 700oC

Cement Plants: Coal

2019-11-16  London coal gas production began in 1813 and by 1842 was producing 300,000 tons of coke a year, so coke was also readily available, and, being essentially a waste product, was cheaper than coal. Early cement plants used coal for drying slurry and for power generation, and coke for kiln burning. Per tonne of clinker produced, consumption was around 0.5 tonnes of coke and 0.1 tonnes of coal.

2016-7-30  From the above discussion, it is clear that 76.36 g of coal should be pulverized with raw meal to produce one kilogram of the clinker, which is equivalent to 1.55 kg of the raw mix. This can also be calculated that for one kilogram of raw meal, 49.27g of coal is required. But the observed heat required in cement kiln is 850 kcal/kg, which is almost double to that 420 kcal/kg.
