Vertical Mill Working Principle:
The main motor drives the grinding disc to rotate through a reducer, and the material enters the vertical mill main machine through a screw conveyor. It is then subjected to gravity and falls to the center of the grinding disc. At the same time, the airflow generated by the fan enters the main machine through the air inlet. Under the action of centrifugal force, the material moves uniformly from the center to the edge of the grinding disc. When passing through the roller conveyor area on the grinding disc, it is crushed by the grinding rollers, and large blocks of material are directly crushed. Fine particles of material are compressed to form a material layer for inter particle crushing. The crushed material continues to move towards the edge of the grinding disc until it is carried away by the strong air flow of the annular guide groove on the periphery of the grinding disc. Coarse materials fall back into the grinding disc due to their high gravity and are ground again; Fine materials enter the powder selection system above the main machine for classification as the airflow rises. Under the action of the rotor blades of the classifier, coarser particles are knocked off by the blades and returned to the grinding disc for grinding. Qualified fine powder will be carried out of the powder selection system with negative pressure air flow, enter the dust removal equipment, and then collected by the powder collector to form the finished product. In addition, other large particle materials and debris will fall into the lower chamber of the mill during grinding, and be scraped into the slag discharge port by the scraper, effectively ensuring the quality of the finished product.
By adjusting the pressure of the hydraulic system, the grinding roller pressure can be adjusted to adapt to different hardness raw materials within a certain range. The rotor speed of the grading system with multiple grading wheels can be adjusted and controlled, and various qualified products with different specifications can be obtained.
