Ball mills are equipments which has balls as grinding media and used for last step of grinding process. There are many factors which effect grinding performance of ball mills like liner design.
The mill is designed to handle a total ball charge of 324.5 t at 100 loading with a percentage filling of − Water spray is being done into the 2nd Chamber of the mill even though the cement temperature is mill liner conditions, grinding media charge and product size requirements.
Compared to ball mills is well understood within the industry. The use of tower mills as an energy media charge of 4 mm diameter, in a 4 litre chamber and ignore the effect of slurry, so physical interactions are solely a function of media specification. Figure 2 Snapshots of flow with left.
Will reduce the ball mill second chamber efficiency and may cause damage to the grinding bodies. Changing the inclination angle of the inclined segment to the opposite, setting it at an angle of inclination from the discharge bottom (Figure 3, c), leads to the “waterfall effect’s” disappearance in the second mill chamber.
