How Portland Cement Is Made Manufacturing Process Of
aug 31, 2009 portland cement can be made by following two different processes a dry one and a wet one. joseph aspdin first made portland cement in his kitchen stove in england in the century. lime and silica make up approximately 85% of portland cement. the materials that are commonly used are limestone, shells, chalk, shale, clay, slate, silica sand, and iron ore.manufacturing of cement involves various raw materials and processes. each process is explained chemical reactions for manufacture of portland cement. cement is a greenish grey colored powder, made of calcined mixtures of clay and limestone. when mixed with water becomes a calculated amount of lime is added in the manufacturing of portland cement, If it is excess in amount, it reduces strength of cement, because it makes the cement to expand and disintegrate. silica: lime undergoes reaction with silica to form dicalcium silicate these play important role in development of strength to cement.
Dry Process For Manufacturing Of Cement
the total consumption of coal in this method is only about 100 kg when compared to the requirement of about 220 kg for producing a ton of cement in the wet process. the dry material undergoes a series of chemical reactions in the hottest part of the kiln and some to percent of the material becomes liquid, and lime, silica and alumina when cement is shipped, the shipping documents may include sack weights. this must be verified by the auditor since only the cement is taxable sack weights must be excluded flow charts of manufacturing process. the following pages contain flowcharts of the manufacturing process of portland cement. the first chart represents theaug 21, 2019 As the per-flow diagram of the wet process of cement manufacturing, the rotary kiln is an essential and important component of a cement manufacturing factory.
