The effects of ball charge pattern cement fineness and two additive materials limestone and pozzolan on the performance of the cbm unit and the quality of cement were investigated. the first and second laws efficiency of the cbm increased 81.8 and 20.6 and the electrical energy consumption of cbm unit decreased 36.5 kwht after ...
The ld ratio of the ball mill was varied in four steps of 1.75 2.1 2.79 and 3.49 and the ball charge filling ratio was varied in three steps of 15 20 and 25. the experiments clearly indicated that the optimal ld ratio and the optimal ball charge filling ratio are different for each feed fineness.
The mill is designed to handle a total ball charge of 324.5 t at 100 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.
