The mix is fed into a circular storage unit called a mix storage. Then, the mix is extracted transversely from the stockpile by reclaimers and conveyed to a mill bin called the mix bin for grinding. The other materials that are used in cement manufacturing, called additives, are high purity limestone, sand and iron ore. The

Another important cement material is coal that acts as an energy source in the cement manufacturing process. For this purpose, the coal is also crushed and stocked in the longitudinal stockpiles and is taken out diagonally by the reclaimers before further grinding of fine coal. Jharkhand has the biggest coal mines in India followed by Orissa, Madhya Pradesh, Chhattisgarh, West Bengal, and Andhra Pradesh. Coal is used for heating the materials at 1450 degrees centigrade to turn
The choice of composition of materials mixture with useful components generally is determined by plant’s geographical location and delivery of materials. The only common feature in all cement production plants is the difficulty of grinding the source material as the material is hard enough and has high abrasiveness.
Ball Mill Ball mills with high efficiency separators have been used for material and cement grinding in cement plants all these years. Ball mill is a cylinder rotating at about 70-80% of critical speed on two trunnions in white metal bearings or slide shoe bearings for large capacity mills. Closed circuit ball mill with two compartments for coarse and fine grinding and a drying compartment with lifters are generally found in cement plants for material grinding. Compartments (filled About 85% of the total energy expended in cement production is used for size – reduction; 75 % in grinding operation alone and 2 - 20 % of the energy supplied to the mill is used for size reduction, the remaining is lost in various activities such as friction between particles, friction between particles and mill elements, generation of heat and sound, vibration and material turbulence etc.
