Since its emergence, the ball mill has experienced uneven development over nearly one hundred years due to different research methods owing to the different economic development levels of nations. Although the efficiency of ball mill is very low, it is extensively applied. Domestic research on energy is basically carried out individually and empirically.
Ball mills, that are commonly used for finish grinding, have high energy demands, consuming up to 3042 kWh/t clinker depending on the fineness of the cement. Complete replacement of ball mills by vertical roller mills (VRMs) with an integral separator – as opposed to the use of VRMs as pregrinding to ball mills – is regarded as a breakthrough.
The ball mill efficiency improve six aspects of this improvement. 1, a ball mill of the amount of water added. Ball mill, the water content of the ore processed much influence to the work efficiency of the ball mill, and therefore appropriate to add water on the ore being processed by the ball mill, avoid overly dry raw ore in the ball mill ...

Factors Affecting Ball Mill Grinding Efficiency. The following are factors that have been investigated and applied in conventional ball milling in order to maximize grinding efficiency: a) Mill Geometry and Speed Bond (1954) observed grinding efficiency to be a function of ball mill diameter, and established empirical relationships for recommended media size and mill speed that take this ...
efficiency of operation increases. This is caused by the greater height of fall and ... Since faster grinding rates are typical with steel ball mills, more economical production will be the result. All but the finest white and pastel ... Estimated charge factors for alumina media is 9 pounds per gallon and 14 pounds per gallon for zirconia.
Horizontal mills, almost exclusively ball mills, are widely used in the cement industry to grind materials into the required size. If the equipment is not operating at optimum efficiency, the result will be excessive energy and maintenance costs, reduced throughput and increased downtime. This can cause losses in both production goals
