Semi-Autogenous Grinding (SAG) Mill. Wet or dry; Higher capacity than A-G mill grinding; Primary, coarse grinding (up to 400 mm feed size) Grinding media is grinding feed plus 4-12% ball charge (ball dia.100- 125 mm) High capacity (short retention time) Less sensitive to feed composition (critical size material) Semi-Autogenous Mill

factors that affect the grinding effect of overflow type

Therefore, it is necessary to set appropriate pulp density and feeding speed for the sake of better grinding performance. 04 (4) Mill Circulating Load. Properly increase the mill circulating speed is conducive to the discharge of ore particles and improve the mill grinding performance. Usually, the suitable value for mill circulating load is 150% to 600%. Xinhai is committed to adjusting the mills grinding performance …

a specific energy-based ball mill model: from batch

Feb 01, 2016 · A specific energy-based size reduction model for batch grinding ball mills was reported in a previous paper (Shi and Xie, 2015). A discharge function modified from the Whiten classification efficiency equation has been incorporated in the size reduction model to extend its applications from batch grinding to continuous operation

factors affecting ball mill grinding efficiency

Apr 22, 2018 · The following are factors that have been investigated and applied in conventional ball milling in order to maximize grinding efficiency: a) Mill Geometry and Speed – Bond (1954) observed grinding efficiency to be a function of ball mill diameter, and established empirical relationships for recommended media size and mill speed that take this factor into account
