Efficiency of stirred ball mills Semantic Scholar

Stirred mills were first introduced in the 1950`s as an alternative to ball mills in a regrind application. Since then they have been used to grind a range of materials from limestone to coal to sulfide concentrates. A laboratory tower mill was used to investigate the effect of some variables on the power requirements of a plant mill. The grinding laws were tested for fine grinding and Charles ...

According to the theoretical analysis and experimental verification, we can conclude that the energy consumption of stirred mill is proportional to the grinding time. When the capture angle is equal to the friction angle, the capture angle, capture granularity and capture size are the largest, the grinding efficiency is the highest and the energy consumption is the lowest.
