STEP1: Crushing and pre-homogenization of Portland cement. In the portland cement production, most of raw materials should be crushed, such as limestone, clay, iron ore, coal and etc. The lime stone is the main raw material of Portland cement making, because its big size and high hardness, the lime stone crushing is more important in the cement crushing

Apr 13, 2020 The manufacture of Portland cement is a complex process and done in the following steps: grinding the raw materials, mixing them in certain proportions depending upon their purity and composition, and burning them to sintering in a kiln at a temperature of about 1350 to 1500 ⁰C. During this process, these materials partially fuse to form nodular shaped clinker by broking of chemical
