Vertical Roller Mill Operation

SBM is a high-tech enterprise, involved in research and development, production, sales and service as well. In the past 20 years, we are committed to the production of mining equipment, sand making equipment, industrial mill, provide highway, rail way and water conservancy engineering sand to make high-grade equipment and related solutions.

Vertical Roller Mill Operation

Vertical roller mill, a widely used in the cement industry raw material, clinker preparation, grinding slag, ore, industrial silicon carbide slag, coal and coal chemical industry, power plant desulfurization, coal preparation and other areas of high efficiency energy-efficient grinding equipment. Our set of vertical roller mill drying, grinding, separator, transportation as one, with high capacity, small footprint, low power consumption, easy maintenance, operation rate, the vulnerability of a series of advantages such as long life, Product technology has reached the world advanced level, at home and abroad are widely applied. Our vertical roller mill in the introduction of foreign advanced technology, based on, has formed a complete independent intellectual property rights, through innovative research and development, design and manufacture a variety of purposes specifications and construction vertical roller mill.

Advantages of vertical roller mill

  1. Vertical roller mill adopts the principle of grinding material layer material, low energy consumption, grinding system power consumption 20 to 30 percent lower than the ball, and with the increase of raw water, the energy-saving effect is more significant.
  2. Grinding wear a small, high utilization. Because vertical roller mill operation no direct contact between the metal, so the grinding wear small, unit product wear is generally 5 to 10 g / t, a small metal contamination of the product.
  3. Grinding roller sleeve can be used upside down, to prolong life and reduce production costs.
  4. Vertical roller mill operation easy and reliable operation and easy maintenance.

Vertical roller mill works

Rotating disc driven by the main motor reducer, while the hot air from the inlet into the body of the mill stand, the central disc material falls from the feed opening, under the action of centrifugal force, the material from the disc moves to the edge of the center even after the powder on disc When the grinding roller area by rolling mill rolls, bulk material directly crushed, squeezed after the formation of fine material bed intergranular crushed material. Crushed material to the disc edge continues to move until it is taken away by a strong air flow at the air ring, while the larger particulate material to fall again on the disc to continue pulverization, the airflow in the upper portion of the material through the separator, the rotor Under the action of the blade, coarse grinding back on the disc, together with the air passing the powder out of grinding, is collected powder collector system is collected shall be vertical mill grind powder products. When mixed with iron materials and other debris with material movement to the edge of the disc, which can not be due to the large wind from its own weight, fell to the mill to be installed at the bottom of the inferior vena disc scraper plate scraped into the slag discharge port outside the machine .
