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 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 factor into account. As well, mills with different length to diameter ratios for a given power rating will yield different material retention times ...
EF1 Dry grinding for the same range of work as wet grinding, dry grinding requires 1.3 times as much power as wet grinding. EF2 Open Circuit Grinding when grinding in open circuit ball mills, the amount of extra power required, compared to closed circuit ball milling, is a function of the degree of control required on the product produced.
This project aims in developing a system engineering approach for understanding, optimizing and scaling industrial dry grinding processes, with a special focus on the manipulation of the material properties and, thus, the grinding and classification efficiency by grinding aids. Grinding aids are defined here as liquid or dry substances that are added
The advantages of a ball mill are leading to low efficiency, but significant specific energy consumption for grinding material compensates for beneficial effect when using the mill. In most cases, the Ball Milling Technique uses mechanical alloying and milling approaches, which is not new. In short, the ball mill has been widely used in size comminution for mineral dressing and many other applications.
