AG mills

AG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill and some or all of the work done by a ball mill. AG mills are also an optimum solution for wet grinding since crushing and screening in these cases can be difficult, if not impossible. Lower lifetime cost

Investigation of Fundamental Mechanism of Crushing of

When clods and two rods are combined in the jar (), the clods break into smaller particles (lt;2 mm diam) within two minutes of stirring.This means that the use of rods is important for crushing. Figure 7 shows the frequency distribution of soil particle sizes after crushing as a bar chart. That 65% of the particles were reduced to 1 mm diam shows that our rod mills design requirements work well.

Rod mills, how they function Mine Engineer.Com

Rod mills operate at lower speed than ball mills since the rods are rolled and not cascaded. For an equivalent grind, a rod mill uses less steel than a ball mill because of the lower speed and better contact between the media and ore. The rod charge must be maintained in good working condition, and broken and worn rods must be removed.
