Vertical roller mills: The new leader in grinding technology
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 considering that
