Working principle of Vertical Roller Mill

The main motor drives the grinding disc through the reducer, while the hot air enters the broken body from the inlet, and the material falls in the center of the grinding disc through the inlet. Under the action of centrifugal force, the material moves evenly from the center of the grinding disc to the edge. When the grinding disc is grinding the roller table area, the roller is crushed and the bulk material is pressed directly. Crushed and fine materials are extruded to form a material bed for intergranular comminution. The crushed materials continue to move to the edge of the grinding disc until the strong airflow is taken away by the wind ring. In the material taken by the airflow, the larger particles are re dropped to the grinding disc under its own gravity, and the rest of the materials enter the high efficiency dynamic separator into the powder classification, and in the efficient dynamic separator with the air flow. Under the action of the blade, the material that does not meet the requirements of the fineness is returned to the grinding disc for grinding. The material that meets the requirements of the fineness is collected in the pulse dust collector with the gas flow through the pipe, and the finished powder is discharged through the discharging device. When the refractory debris, such as iron, mixed with material in the host, moves to the edge of the grinding disc, it can not be blown by the wind because of its own weight, and the scraper plate which is installed in the bottom of the mill is scraped into the slag outlet at the bottom of the grinding disc and expel the outside of the main engine.

Low cost of comprehensive investment

The Vertical Roller Mill covers an area of small area: the Vertical Roller Mill is composed of crushing, drying, grinding and grading. The system is simple and the layout is compact. The area is about 50% of the ball milling system, and it can be arranged in the open air. So a large amount of investment is reduced. Strong drying ability: internal hot air directly contact with the material, drying ability is strong, can save a dryer, save land area, save energy, and through adjusting the hot air temperature, can easily deal with different humidity of the material.

Less wear and tear: as the work roller is not directly contact with the grinding disc, and the grinding roller and the lining plate are made of high quality material, so the Vertical Roller Mill has long service life and less wear.

Working principle

When the Vertical Roller Mill works, the material falls in the center of the grinding disc through the spiral feeder, and the centrifugal force produced by the reducer to drive the grinding disc is driven by the main engine, so that the material moves evenly around the grinding disc. When the material passes the roller track on the grinding disc, the roller is crushed and the large pieces of the material are crushed directly. The smaller particles are subjected to the material. After extrusion, the material bed is formed to comminution between particles.
After being crushed, the material continues to move to the edge of the grinding disc, and is graded by the air flow from the inlet of the inlet to the pulverizing machine. Under the action of the blade of the pulverizing machine, the powder that does not conform to the particle size requirement falls into the grinding disc and regrinded, and the standard powder is collected through the pulverizing machine and the pulverized dust collector is collected and collected. The body is the finished powder. The iron and other impurities mixed in the material, because it is difficult to grinding and its own gravity, through the edge of the grinding disc, can not be taken away by the air flow into the mill lower cavity, the scraper plate is sent to the spit mouth, and the outside of the main engine is discharged.
