grinding media size distribution in mill

Jul 01, 2003 · Figure 3 depicts the effects of media size on grinding times. From this plot, it is shown that a target fineness of 80% < 2 microns is normally achieved in 315 minutes of recirculation milling with 1.0 to 1.4 mm grinding media. By reducing the media diameter to 0.6 to 0.8 mm after 90 minutes, the target grind is achieved in only 150 minutes

    lapping wikipedia

    Lapping is a machining process in which two surfaces are rubbed together with an abrasive between them, by hand movement or using a machine.. This can take two forms. The first type of lapping (traditionally called grinding), involves rubbing a brittle material such as glass against a surface such as iron or glass itself (also known as the "lap" or grinding tool) with an abrasive such as

    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

    The attrition grinding action, vertical arrangement, and the finer media size distribution contribute to make stirred mills energy efficient grinding machines. Vertimill® energy savings can range from 30% to greater than 50% compared with traditional mills, and the SMD energy savings can be far greater than 50% of ball mill energy in fine grinds

    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
