COAL FUEL OIL AND NATURAL GAS FOR CEMENT …

Coal, fuel oil and natural gas are the most commonly used energy carrier in cement industries. The energy use for cement production is distributed as follows:- 92.7% for pyro-processing 5.4% for finishing grinding and 1.9% for raw grinding (Choate, 2003). The choice of fuel use entails the level at which green house gases (GHG) are emitted, the cost of cement and the quality of the cement produced.

Which type of coal use by cement industry.

None of the above! In the general coal production silica andimestone are used. Coal is only used for burning the klin to 1400 c to produce the concrete. The other method to produce concrete is by fly ash. Which again is not coal but a by product of burning coal which flies out and is collected using electrostatic precipitation.
