Apr 29, 2017 Then in ball-wear formula (25), T = 6.9/K Log10 Da/Db; but from (29), K = Rt/Wt. Then T = 6.9Wt/Rt Log10 Da/Db T is 1 day, Wt is the original weight of the ball charge, and Rt is the ball wear for one day. Then Log10 Da/Db = Rt/6.9Wt are all known, and it is only necessary to solve for Db, the diameter of the balls to be added.

Nov 01, 2017 re 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 explained and it is based on material hardness and biggest size.
A grinding mill (Ball Mill) is used to grind the cement clinker into fine cement powder. Grinding Aids are used to improve the grinding efficiency and reduce power consumption. This paper discusses the grinding aids mechanism and improvement in grinding efficiency due to various grinding aids viz .polyols, amines .
