Stirred media mills have been increasingly used in ultra-fine grinding. The VXPmill is a vertical high speed stirred media mill for grinding mineral ores with high efficiency. Since it is a new technology in the industry, there is little understanding on the breakage kinetics of the mill. In order to gain more knowledge about the VXPmill, computer modelling of the mill was performed

Effects of Grinding Media Shapes on Ball Mill Performance

4.4 Wear Mechanisms Inside Industrial Ball Mill Grinding media wear is a contentious subject and many theories exist regarding the laws governing the process. Measurement of ball size distribution within a ball mill can provide data on ball wearing mechanisms and indicates the relative intensities of abrasion and impactive forces within the mill.
