Abstract. Based on screening analysis, laser size analysis, grindability and rigidity tests of samples collected on line from a cement and a power plant, a simulation Proven commercially, the OK™ mill is the premier roller mill for finish grinding of Portland cement, slag and blended cements. The mill consistently uses five to ten percent less power than other cement vertical roller mills, and in comparison with traditional ball mill operations, the energy requirements for the OK cement mill isOK™ cement mill The most energy- efficient mill for

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 The vertical roller mill is also one of the high compression grinding technology and has an important position in the cement and mineral industry due to their low energy consumption, high drying capacities, and operational reliability. However, in the literature, the lack of studies on the energy estimation of this equipment creates a gap inPredicting the grinding energy of vrm depending on material
