CEMENT MANUFACTURING PROCESS: RAW GRINDING

Dry grinding requires approximately 30 % more energy / wt of ground material Dry mills need more mill volume than comparable wet mills However, the increased metal wear of the grinding media and the mill liners for wet grinding, equalizes the additional energy costs of dry grinding procedures ~ 30 40 % of wear costs in wet grindingre Cement Mill Grinding Media H there, These are just the basics if you want to accurately do it you have to fill it up to 80% BC and then do a longitudinal sieving and then correct the BC based on the results The biggest ball determination is explainedCement Mill Grinding Media Page 1 of 12 Shape, size, and weight of the grinding media 3 Friction between the lining and the grinding media 4 Internal friction mill charge Figure: Grinding media 441 Grinding Ball Charge in Mills: According to Levenson, the optimum grinding ballCement mill notebook SlideShare
