al., 2005). In stirred mills there are no freefalling 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 ...

The vertical stirred mill employed saved about 4 million kWh/year in electrical energy, reducing annual operating costs by about 325,000. Larger horizontal stirred mills were later installed at the Embako mines in BC. Ball mills are often used to grind feedstock into particles of 30 to 100 microns in size.
