Chat OnlineRod mills have become niche comminution devices since about 30 years ago because of mechanical limitations on rod length and the need to have an aspect ratio for the mill that avoids tangling a potentially deadly failure for those tasked with rectifying the problem rod mills have a maximum installed power of about 25 mw
Chat OnlineOvercharging results in poor grinding and losses due to abrasion of rods and liners undercharging also promotes more abrasion of the rods the height or depth of charge is measured in the same manner as for ball mill the size of feed particles to a rod mill is coarser than for a ball mill the usual feed size ranges from 6 to 25 mm
