Media stress intensity analysis developed for high-speed horizontal mills was modified to include the effect of gravitational force in the vertical stirred mills such as the Tower and SAM units.
1 ABSTRACT This study provides a comprehensive understanding of the fine particle grinding process in stirred media mills. Calcium carbonate was chosen as the feed material. The e
Media stress intensity analysis developed for high-speed horizontal mills was modified to include the effect of gravitational force in the vertical stirred mills such as the Tower and SAM units.
Stirred media mill recently is commonly utilized among mining process due to its high stressing intensity, remarkable energy efficiency and reliability. However, understanding for process is still not enough and some gap still exists for improving efficiency by using wet grinding method on vertically stirred media mill.
The popularity of stirred media mills has risen in recent times. CITIC HIC has developed our own range of vertical stirred media mills to complement our conventional grinding mills range, research and development team in Australia and CHina constantly working improving technology and efficiency of …

Stirred Mills have been proven to provide energy savings compared with traditional ball mills. The finer the product required, the more efficient stirred mills will be than a ball mill. The attrition grinding action, vertical arrangement, and the finer media size distribution contribute to make stirred mills more energy efficient grinding machines.
Tower mills, often called vertical mills, stirred mills or regrind mills, are a more efficient means of grinding material at smaller particle sizes, and can be used after ball mills in a grinding process.
stirred mills will vary from site-to-site and from mill-to-mill. Optimization of a given stirred mill with respect to specific energy input depends on the complex relationships between a large set of parameters. Examples include mill speed, media size, media loading, slurry density, slurry flow rate, slurry rheology, feed material characteristics.
