Coal is the basic fuel used in the Indian cement industry While it mainly provides the requisite heat and temperature, the ash content in the coal also combines chemically with the limestone to help form cement clinker In India, coal will, of course, continue to be the dominant fuel for a verylong time 247 online type of coal used by Cement
For the preparation of small quantities of powder many types of mill are available but, even so, the ball mill is frequently used. For the grinding of the largest quantities of material however, the ball, tube or rod mill is used almost exclusively, since these are the only types of mill which possess throughput capacity of the required magnitude.
fly ash was used in 2005 as pozzolan in cement, the concrete industry itself used almost 14 Mt of fly ash mostly as a pozzolan, as well as about 1 Mt of bottom ash as an aggregate7. LowNOx burners at power plants produce a highcarbon fly ash that, unless treated, is unsuitable as a pozzolan, but can
Coalderived coke was the fuel used in most static kilns and so was the dominant fuel in the cement industry in the nineteenth century. Coal could not be used in static kilns in which the fuel is fed in with the raw material, mainly because, during the gradual heatup of the charge, the fuels volatiles are lost without ignition, so wasting up
