Rod Mills
A rod mill uses steel rods as the grinding media in tumbling mills is an efficient means to feed ball mills a product finer than could be made in a crusher but coarser than could be made in a ball mill. The principal use for rod mills, which were invented to make ball mill feed in a wet-grinding rod mill-ball mill circuit. Rod mills came into use in the United States beginning in 1900s and ...

· Although ball mills can still be found in the regrind circuits in a number of mineral processing plants, their energy consumption is high, and size reduction efficiency is low. The need to grind the ore finer to liberate the minerals and the dramatic increase in the cost of energy in the mid 1970s resulted in more efficient comminution processes being sought.
