Energy Use of Fine Grinding in Mineral Processing

Dec 18, 2013· For example, the figure suggests that a mill operating with an F80 of 100 μm should use 3-mm media, while a mill grinding to below 10 μm would need to use 1-mm media. To reduce a feed of 90 μ m F80 to 10 μ m P80, Figure 9 suggests that comminution be done in two stages (two Isamills or SMDs in series) for optimal efficiency.
