01/01/2005 No discussion of comminution and classification circuits would be complete without some mention of process control (further details may be found in Chapter 9).
An important part of the comminution circuit is size classification. This can be accomplished with screens or cyclones or a combination of the two. Since cyclones classify on the basis of both particle size and specific gravity, cyclone classification in the grinding circuit directs coarse siliceous particles to the cyclone overflow. In a reverse flotation circuit, these coarser siliceous

The application of High Pressure Grinding Roll (HPGR) in comminution circuits is well established in processing cement, diamonds and iron ore. Recently, the application of HPGR has been extended to high-tonnage precious and base metals operations with hard ore. This is due to the HPGR: being more energy-efficient than grinding mills, not requiring steel grinding media, and providing higher
25/03/2019 If there will be changes in ore type, one should assess how comminution circuits handle ore variation. In the case of a SAG and ball mill circuit either machine could be the bottleneck. Corrective actions depend on both circuit and how much ore variation is experienced. For example, when SAG limited and if there is a pebble crusher, the crusher closed side setting can be decreased. This is a

07/08/2019 The flexibility of HPGR provides advantages for a variety of comminution circuits. HPGRs can handle a wide variety of ores and particle sizes, from fine pellet feed all the way up to coarse grinding of 75mm magnetite iron ore. Alongside their greater tolerance for ores of different hardness and variable roller speed, HPGRs promote greater flexibility in feed conditions and circuit design than
