The three roller mills are highpressure (very small roll distance) wet grinding equipment, so safe operation is very important. When the three rollers are working, the nonworkers on site need to keep a certain distance from the three rollers. Beware of personal limbs and foreign objects (clothing, shovels) getting caught in the feed rollers ...

The two most common compressive comminution technologies are the high pressure grinding roller (HPGR) and the verticalrollermill (VRM). For now, the HPGR has already presented in a noteworthy number of mining projects whereas VRM technology, a new entrant, is still not fully accepted. This is considered a resistance to change considering that ...

high pressure over a short time. The pressure forms microcracks in the feed particles, leading to the generation of a large amount of fine material. For upgrade projects, using an HRP together with a ball mill significantly reduces overall specific power consumption and increases system production. In ball mills, less power is required

1.. IntroductionHighpressure roller mills are advantageously equipped with screw feeders if a fine material is fed containing a high fraction below 100 μm 1, screw feeder creates an additional pressure upon the material entering the mill and improves by that the material introduction, which is disturbed by the air squeezed from the voids as the particle bed is compacted.
