Vertical stirred mills are usually charged with media occupying 80% of the mill volume which is in sharp contrast to tumbling mills that are seldom charged more than 40% of their volumes to allow space for the tumbling action to develop. The stirred mills are charged with a media size of 1012 mm and operated at a maximum tip speed of 38 m/s.

stirred mill that operates with very high power intensities (up to 300kW/m3) compared to ball or tower mills (with less than 40kW/m3). This high power intensity enables the IsaMill™ to process coarse particles to ˜ne product sizes with small media at high throughput. The result is large scale, ef˜cient grinding for both coarse and ˜ne

01.07.2003· With a better grasp on the theories behind high-performance media mills, the process of determining the best media mill for your application will not be so painful. There are also questions you can ask an equipment supplier on the practical functions of the mill to judge the maintenance and operator friendliness of the unit for further differentiation.
