% of grinding media in ball mills for both chambers
Can you tell me anybody about how much % of grinding media required for first/second chambers & Ball to Clinker Ratio for cement grinding with 3000 blaine.How to estimate the % of grinding media with empty height. How to estimate the Size of the of the grinding media for first and second chambers. Mill dimensions are:
Dia.(m) Lengh(m) Vol(m3)
1st cha. 4.88 5.28 98.85
2nd cha: 4.88 9.58 179.27
Grinding media density for 1st chamber: 4.5 tons/m3 and 2nd chamber: 4.6 tons/m3

Re: % of grinding media in ball mills for both chambers
The volumetric filling degree of modern finish mill is 27-30% for the first chamber and 24-27% for the second chamber.In your specific case first chamber may be loaded 114.76 MT- 127.52 MT and in second chamber you may load 197.91 MT - 222.65 MT.You should start media loading in both the chambers from lower value first and based on grinding performance you may increase the load in phase manner.Grinding media density for first chamber you should take 4.3 t/m3.
