Why coal is needed in cement industry? - Origin of coal

A cement factory with a capacity of 2000 tons per day can save up to Rs300 million a year by use of a mixture of local and imported coal. What fuel is used in cement kilns? Traditionally, fossil fuels [coal, pet coke as well as a limited amount of gas and oil] have been burnt to generate the temperatures of around 1450oC needed to produce cement. World-wide, waste-derived fuels have been used for many years to partially replace fossil fuels in cement manufacture.
