The two most common compressive comminution technologies are the high pressure grinding roller (HPGR) and the vertical-roller-mill (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 …
Therefore, ease of replacement and regeneration is a major feature of the mill. The MVR mill has a modern hydraulic system used in operation and for maintenance alike. With this new type of roller suspension, the rollers can be swung out of the mill in a controlled way – for ease of replacing the one-part grinding roller tires.
