Stirred media mills in the mining industry: Material ...

This has been understood since before stress intensity theory was developed; for example, Mankosa et al. in 1986 found that dry stirred media milling of coal with different feed sizes and ball sizes found that a ratio of ball size to feed size of around 20 gave the highest breakage rate, with a very sharp decline in rate at lower ratios and a ...

Effect of media size in stirred ball mill grinding of coal ...

The stirred ball mill is regarded as one of the most efficient devices for micronizing coal. Using a 13.4 cm batch mill, the optimum operating conditions have been determined in terms of media size, feed size and media type. The rate of breakage determined with monosized feeds are compared on the basis of specific energy consumption.

Stirred mills are particularly effective for the fine and ultra-fine grinding sizes where the performance of standard ball mills typically falls off: below 100 microns. The output particle size in a ball mill is largely a function of the size of the steel balls used as grinding media. Large media can impart more energy to the feed material ...

The working principle of ball mill - Meetyou Carbide

Therefore, in the rolling ball mill, the grinding efficiency is increased as the ball diameter decreases. It has been proven that the highest grinding efficiency can be obtained with a small ball of .mm diameter. However, the ball diameter is too small to wear too fast, and it is also difficult to discharge due to the small gap of the ball.

Stirred Milling Technology – A New Concept in Fine Grinding

al., 2005). In stirred mills there are no free-falling possibilities for grinding media, meaning that impact action does not occur. The bead size is small, typically 1 to 6 mm which means a large amount of contacts and high grinding efficiency especially in the finest range, where ball mills are not effective or cannot reach P80 10 to 40 µm.

Grinding Media - 911Metallurgist

The Azzaroni equation indicates that the correct ball size for the 2.93 m mill is 81 mm. Years of experience show that a 76 mm ball grinds the coarse particles most effectively. Ball size distribution is governed by the wear law of the mill and by the wear characteristics through the cross-section of the balls charged to the mill.
