Vertical Roller Mill is mainly applied in the grinding process of metallurgy, building materials, chemical, mining and other mineral industries, and suitable for grinding quartz, feldspar, calcite, talcum, barite, fluorite, rare earth, marble, ceramic, bauxite, manganese ore, iron ore, copper ore, phosphate rock, red iron oxide, zircon sand, slag, cement clinker, activated carbon, dolomite, granite, garnet, iron oxide yellow, chemical fertilizer, compound fertilizer, fly ash, bituminous coal, coking coal, lignite, magnesite sand, chrome oxide green, gold, red mud, clay, kaolin, coke, coal gangue, porcelain clay, kyanite, fluorspar, bentonite, rhyolite, pyrophyllite, shale, purple stone, Diego rock, basalt, gypsum, graphite, silicon carbide, thermal insulation materials and other non-flammable burst materials whose Mohs hardness are below 9.3.
Vertical Roller Mill Has Many Features As Follow:
1. Composite separator improves the efficiency of the powder.
2. With the function of automatic lifting and falling , can realize no-load starting.
3. Welded type arc plate is used for sealing, it features simple structure, reliable performance, well-sealed structure.
4. By means of the roller swing-out device, the grinding rollers can be turned out of the mill, which is in favor of maintenance.
5. The limit mechanism avoids the fiction and crash of metals between grinding roller and grinding plate, increasing the rotating stability and security.
6. Operating pressure of hydraulic system is low, can reduce the leakage failure and the mill vibration , is good for operation and management.
7. The centralized circulating oil lubrication is applied to the grinding roller bearings, which ensures the bearing operate at constant temperature and with pure oil, so that longer service life is achieved.
