Cement Kilns: Size Reduction and Grinding
Raw materials of the cement plant are mostly from open-pit mines, and the ore size of large mines can reach 1.5-1.8m. In the preparation of cement raw materials, we first need to crush limestone, gypsum, clay and other materials into proper size to facilitate the subsequent transportation and storage, at the same time make full preparations for the next process (cement raw materials grinding).
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 …
The cement industry processes requiring fine grinding are rawmix preparation, fuel preparation and grinding of clinker to make cement. All three may require a preliminary crushing stage. In the case of raw materials, attempts have always been made to minimise the amount of crushing needed by extracting the rock in the finest possible state.
