Grinding Mills also know as Semi-Autogenous (SAG), Ball or Regrind Mills are used in the primary or early stages of pulverizing the ore in the process plant. This initial grind of the ore is typically completed in two or three stages. The mills are driven by large high

2013-8-1 At this plant, a 3.962 × 5.791 m regrinding tumbling ball mill with an overflow discharge is used to grind and subsequently liberate locked valuable minerals from an entering feed ground to −300 μm using primary and secondary milling processes in a circuit closed with cyclones. The discharge of the regrinding mill is mixed with the rougher and scavenger concentrates and then sent to the secondary

2021-6-15 The efficiency of the classifiers is also important when we look at the regrind circuit and not just the mills. Creating slimes is not going to help flotation. The achieved classification efficiency at full scale can be quite poor (in my limited experience). Simple preventative maintenance practices can make dramatic differences.

2009-6-1 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 ...
