Grinding Process and Grinding Machines for Manufacturing cement?

Question: I need to Know information about grinding process and grinding achines for Manufacturing cement?

Reply: Two grinding processes are applied in existing raw grinding plants, wet grinding (slurry mills) and dry grinding.
Since vertical roller mills are more economical than ball mills and also have the ability to dry extremely wet materials the ball mills were not considered in the latest evaluations of raw grinding plants. However ball mills are still common in wet grinding plants.
