Material ground consists of limestone, cement rock, marl or marine shells along with secondary materials usually shale or clay A typical raw mix consists of 7585% limestone, 1225% shale, the balance consisting of silica or quartzite and iron oxide The second major component in the production of cement is the cost of raw materials The primary raw material that’s used is limestone Raw materials account for 30%–40% of the cost of salesMustknow: The cost elements of cement Market Additive costs vary depending on the source and transportation cost of the additives; the limestone dust and cement kiln dust are often waste byproducts with a zero or negative cost (a disposal cost) An industry expert estimates the cost of the additive blend at $10/ton The additive costs is then 50,000 tons x $10 = $500,000Cement Industry Standard Practice to Add a Percentage

Energy consideration in cement grinding

o ~ 25 % of cement cost is due to energy costs, of which: o ~ 50 % is for electricity, mainly for grinding limestone and/or extenders such as slag, flyash or other pozzolan o Energy consideration in cement grinding makes sense: it decreases production cost Therefore, a cement kiln can also be used as a waste treatment device Waste materials will be discharged safely after staying in the kiln for about 8 s In a cement production line of 3 000 t / a, the cement kiln can treat nearly 10 × 104 tons of waste, basically realizing the cost 5 Costsaving Tips for Portland Cement Manufacturers data from: Schiller, B, and Ellerbrock, HG, “The Grinding and Properties of Cement with Several Main Constituents, ” ZementKalkGips, as discussed in The Use of Limestone in Portland Cement: A State of the Art Review, PCA EB227, 2003 Ball millground PLC: fineness relationships of composite cement, LS and clinker fractions 07PortlandLimestone Cement Institute for Transportation

Understanding How The Indian Cement Industry Works

However limestone is a natural resource and more than 65% of India’s limestone comes from five states of Madhya Pradesh, Rajasthan, Andhra Pradesh, Gujarat and Chhattisgarh So companies have two options Make cement in the areas where limestone is available and the ship the finished good to those parts of country that want cement, or Cement manufacturing plants are located near the limestone sources for easy access to the raw materials or else it turnout to be expensive to transport the materials from outside The next major ingredient is clay which have to be located around 2530 km within the plant premises to minimise the cost incurred in transportationManufacturing process of cement Wet Process
