This investigation has shown that a high-pressure roll mill is significantly more energy-efficient than the traditional ball mill. Further energy efficiency can be achieved by grinding taconite in a hybrid mode, whereby the material is first ground in a high-pressure roll mill and then in a ball mill.

In the past 20 years, the energy-efficient comminution technologies, including high pressure grinding rolls (HPGR) and high speed stirred mill, have been developed and adopted in the hard-rock mining operation in order to reduce the energy consumption and .
Rod mills are less common than ball mills for grinding minerals. The rods used in the mill, usually a high-carbon steel, can vary in both the length and the diameter. However, the smaller the rods, the larger is the total surface area and hence, the greater the grinding efficiency. Autogenous mill

High pressure grinding rolls are an energy efficient grinding solution, and now has improved this technology even further. The HRC™, our innovative approach to HPGR technology, is like no other HPGR on the market.
high pressure wet ball mill rolls graphite - icchmt2017 . On a 11'-6" x 22'-0" Ball Mill, the trunnion bearing lubrication system provides continuous low pressure flood oil for cooling and lubrication of the bearings, and high pressure oil for hydrostatic lift of the feed and discharge trunnions during start-up of the mill.
To make the mill more efficient, some roll mills are equipped with a system allowing to guarantee a high pressure (10-50 bar) in between the rolls. It is also mandatory for these mills to have a spring system allowing to release the pressure if the constraint is too important ( foreign body for example) and avoid mechanical damages.
Inspection and maintenance of high pressure roller mill. Figure 4 Highpressure roller mill bearing ball crushing and wear For high pressure roller mills the balls in the bearing have an important position Usually if the ball may be injured inside the ball due to uneven force or other reasons the final result is the same as that in Figure 3
By shifting more of the particle liberation to the high-pressure grinding roll, substantial savings in power consumption can be achieved. HPGR test results published by Grier (1992) on gold ores from the Mt. Todd project showed significant energy savings for a HPGR/Ball Mill circuit as compared to a SAG/Ball Mill plant.
