• Energy Use of Fine Grinding in Mineral Processing

    Dec 18, 2013However, it must be noted that the product size to which a mill can efficiently grind depends on the feed material, the F80, and media type and size. A Vertimill has been used to grind to sizes below 10 μm. The phenomenon of overgrinding is largely the result of using media that are too large for the product size generated.
