Other materials like slag, fly ash, ash of coal etc may also be added in required proportion to get the final cement powder. The main fuel used for firing preheater cyclone and rotary kiln is coal. Therefore, coal plays an important role in the manufacturing process of cement. Based on theCoal Mill – Coal Mill In Cement PlantThe coal mill grinding system is an important part of the dry process cement manufacturing. In cement plants, we usually adopt the air swept coal mill system or vertical mill system as the pulverized coal preparation system, which is arranged at the cement kiln head or kiln tail to provide fuel for clinker calcination. However, due to the flammable and explosive characteristics of pulverizedPROFESSIONAL CEMENT PLANT OPTIMIZATION, . · Modification of the coal mill for operation with pre-heater exhaust gas for high volatile coal and utilization of 14 % RDF in the pyro-system. • Increase of efficiency and capacity of pre-heater, calciner and cooler.
