What is the manufacturing process of Portland cement
The process used by cement manufacturing companies in india consists of grinding the raw materials, mixing them intimately in certain proportions depending upon their purity and composition and burning them in a kiln at a temperature of about 1300 to 1500 C, at which temperature clinkers are formed and they are made into fine powder in addition with 3 to 5% of …
