Vertical Mill

Vertical Mill

Vertical mill is a kind of ideal large grinding equipment, widely used in cement, electric power, metallurgy, chemical industry, non-metallic mineral industries. It sets the crushing, drying, grinding, sorting conveyor at an organic whole, high production efficiency, can be massive, granular and powdered materials into powder material will be required. Vertical mill belongs to the fine grinding equipment, in the building materials industry for fine grinding hard or soft, medium hardness material, particularly in the cement industry, ceramic industry, electricity sector and more use , such as cement clinker, limestone, clay, China clay, gypsum, feldspar, barite and coal, etc.

Vertical mill has become the first choice of raw material grinding equipment in the cement industry. Large vertical mill grinding capacity has reached 600t/h, the transmission power of 5000kW. The main components of vertical mill grinding equipment:

  1. Nether millstone:  including the guide ring, the wind ring, retaining ring, plate, plate, scraper plate and lifting device, etc.
  2. Grinding roller: grinding roller set for easy wear parts, requirements have enough toughness and good wear resistance.
  3. Powder concentrator: can be divided into static, dynamic and efficient combined classifier three categories.
technique vertical mill

1. Technique and technology is mature and stable

Anyang Machinery Company’s cement vertical roller mill (vertical mill) in the production of cement specific surface area up to 3800 cm²/ g with stable and reliable quality.

2. Reducing the power consumption of cement clinker preparation effectively

According to the display of pulverized coal measured data, the vertical mill can be saving electricity above 30% use of vertical roller mill production per ton cement clinker than traditional tube mill, and the power saving effect is very remarkable.

3. Stable, high-efficiency and environmental protection

There is a low vibration and noise in overall system, and vertical mill equipment with whole sealing, system working under negative pressure with no dust overflow, clean environment. Therefore, cement vertical roller mill meets the national environmental protection requirements. With working mechanism changing, cement vertical roller mill can be reduced friction and improved service life.
