Manufacturing of portland cement – process and material
Methods of manufacturing process of cement. at present portland cement is manufactured by two processes, dry process, and wet process. the main difference between these two methods of manufacturing of cement is that in the dry process, calcareous and argillaceous raw materials are fed into the burning kilns in a perfectly dry state.• vertical roller mill vrm • ring roller mill or horo mill even though there are various types of systems available for cement grinding, ball mills are predominantly used machines for cement grinding in large number of cement plants. in this paper authors are covering the process diagnostic study of ball mill for cement grinding. 2.
