LM Vertical Grinding Mill

LM Vertical Grinding Mill(also called vertical roller mill), which is developed and launched by Zenith. It is designed by our excellent engineers and technical workers, basing on industrial mill research of many years and adopting advanced minerals processing technology. It also adopts many advantages from other types mills all over the world, so as to mix many advantages in one.

LM series Vertical Grinding Mill is generally utilized in the grinding approach of metallurgy, creating supplies, chemical, mining as well as other mineral industries, and appropriate for grinding quartz, feldspar, calcite, talcum, barite, fluorite, uncommon 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 elements as well as other non-flammable burst materials whose Mohs hardness are under 9.3.

LM Vertical Grinding Mill Benefits

  1. It adopts the technology that vertical roller grind material directly on the disc, with low energy consumption; for the roller is not contact with the disc directly in the work, and the roller and liner are made by quality materials, it is of less wear and long life.
  2. Its automatic control system can reach remote control, which is easy to operate; there is the device to prevent roller sleeve contact with disc liner directly, and avoid the destructive impact and severe vibration; we can turn the rotating arm by repairing fuel tank, replace the roller and liner are more convenient, which can reduce the downtime.
  3. It features small vibration, low noise, and sealing device as a whole, and the system also works with no pressure and dust spills.
