Advantages

Vertical roller mill adopts the structure of reasonable and reliable design, with advanced technological process, drying, grinding, choose powder, ascension as a whole, especially in large grinding process, to fully meet customer demand, the main technical and economic index reached the international advanced level. Vertical roller mill can be widely used in cement, electric power, metallurgy, chemical industry, non-metallic mineral industries. Vertical roller mill is especially suitable for all kinds of ores of large milling machining, grinding massive, granular and powdered materials into powder material will be required.

Features

  • 1. Vertical roller mill stand-alone high yield, high crushing efficiency, adaptability mineral crushing.
  • 2. In terms of grinding process, column mill according to the user to immediately drop with product requirements, and can strictly control the product particle size range is divided into, to meet user demand for different products immediately.
  • 3. The vulnerability of wear-resisting performance is good, wear and tear, low cost production continuous stable.
  • 4. Simple operation and maintenance, and high rates of operation, easy maintenance.
  • 5. Low running cost. Use directly on the grinding at the mill rolling grinding materials, low energy consumption; Because of work roller is not direct contact with mill, and the roller and plate made of high-quality material less wear and tear, long life.
  • 6. Easy to operate Reliable operation. Automatic control system can realize remote control, easy to operate; Have prevent roller set and mill lining board direct contact with the device, to avoid damaging impact and violent vibration; Through access rotating arm oil cylinder, more convenient replacement of roller cover, liner, reduce outage losses.
  • 7. Energy conservation and environmental protection. Little vibration, low noise, and the whole sealing equipment, system working under no negative pressure, five dust spillover.
