clinker quality depends on raw material composition,jan 14, 2014 portland cement manufacturing begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called raw meal, which is then heated to a sintering temperature as high as 1450 c in a cement kiln. in this process, the chemical bonds of the raw materials are broken down and then are recombined into new compounds..cement and mining industry electric motors and gearboxes,cement and mining. cement is defined as hydraulic binders obtained by adding gypsum or additives to clinker. clinker is obtained by mixing raw materials such as limestone, clay, marl and iron ore containing silicone, calcium, aluminum and iron oxides at certain rates and cooking them up to a certain sintering temperature..
