They can be used for both plant and test mill data. The cumulative grinding rate through the size of interest is the identical parameter as the ball mill grinding rate calculated from the functional performance equation. Its maximization is the technical optimization criterion for ball sizing studies.
Optimization of the Cement Ball Mill Operation. Optimization addresses the grinding process, maintenance and product quality. The objective is to achieve a more efficient operation and increase the production rate as well as improve the run factor. Consistent quality and maximum output with lower specific power consumption results in lower ...

Nov 16, 2020 The study showed that the combination of the BPR and powder type affects the particle size result. The optimum of BPR at 12 with the number of balls is 60 pieces, and the filling rate is 10.13. The result shows that the horizontal ball mill able to grind the calcium carbonate to a size of smaller than 100 mesh 149 m.

Figure 6 Mill Optimisation Control Strategy. MillSTAR. THROUGHPUT OPTIMISATION. SEGREGATED ORE FEED CONTROL Feed Ratio Optimisation On milling plants fed by a segregated feed supply, such as a stockpile, the varying size and hardness of the mill feed material affects the residence time in the mill and the power drawn.
For overflow ball mills, the charge should not exceed 45 of the mill volume . For grate discharge mills, the charge should occupy about 50 of the mill volume . Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, He, and the radius of the mill, R, i.e.,
