Open Collections

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
