Copper ore grinding in a mobile vertical roller mill pilot plant
Within the scope of the study ore grinding performance of the vertical roller mill was investigated with mobile pilot plant. In this context, chalcopyrite ore of a plant having rod and ball milling circuit was ground under different operating modes e.g., air swept and overflow, and process conditions, then samples were collected around the system.material bed on the grinding table is achieved by sub-roller pressing thereby improving the material coefficient of friction (μ). Over the years, UBE has the well-established 2+2 and 3+3 system of Main Roller and Sub Roller for Cement and Slag grinding. As a feature of UBE’s sub rollers, they are designed to generate sufficient VERTICAL ROLLER MILLS AMCL

Cement grinding Vertical roller mills VS ball mills
For a ball mill grinding OPC to a fineness of 3200 to 3600 cm2/g (Blaine) the cost of wear parts (ball, liners and mill internals) is typically 0.15-0.20 EUR per ton of cement. For an OK mill grinding a similar product, the cost of wear parts depends on the maintenance procedures, i.e. whether hardfacing is applied.In the past, high pressure grinding rolls (HPGR), vertical roller mills (VRM) had positive effects on the overall energy utilization of cement grinding however some quality issues had also beenCements ground in the vertical roller mill fulfil the quality

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 Schnatz, R. et all: Operational experience from India's first MVR vertical roller mill for cement grinding.
