Get PriceThe mill is designed to handle a total ball charge of 324.5 t at loading with a percentage filling of. 29.5% in both the chambers. Both the chambers of the cement mill were charged with 80% of the designed charge, which works out to 86 t in Ist chamber and 172 t in the IInd chamber. The mill is utilised for production of
Get PriceDuring the last decade, semi-finish-grinding plants have been used more and more for the energy efficient grinding of high-quality cement. In 1999, it was found that by decreasing the ball charge filling ratio it was possible to lower the specific energy demand for grinding significantly. It was obvious, too, that the L/D ratio

Get PriceLow filling degrees and low percentage of critical speed do not allow an efficient ball charge action on the material. High filling degrees and high percentage of critical speed lead to ball charge centrifugation and very little grinding efficiency. Mills with high percentage of critical speed can be operated with low filling degrees
Get PriceIncreases in the ball charge distribution and surface hardness of grinding media and wear resistant mill linings have shown a potential for reducing wear as well as energy consumption. This practice can reduce the grinding energy use by 5- 10% in some mills, which is equivalent to estimated savings of 3-5 kWh/t cement.
Get PriceThe ball charge tendency in the 1^{st} compartment is to use the coarser of the gradings available. When producing high Blaine Cement it is the objective to use less tonnage. Achieve nearer 8-9 kWh/t at the target mill output instead to go for a more fine ball charge.
