Vertical Grinding Mill

Product Introduction

When working, the main motor drives the grinding plate to rotate through the reducer. At the same time, the hot air enters the vertical mill body from the air inlet. The material falls from the discharge port to the middle of the grinding plate. Under the action of centrifugal force, the material moves evenly from the middle to the edge of the grinding plate and passes through the grinding plate. When the grinding roller area is on the grinding machine, it is crushed by the grinding roller, and the large materials are directly crushed, and the fine-grained materials are extruded to form a material bed for inter-granular crushing. The crushed materials continue to move toward the edge of the grinding disc until they are taken away by the strong airflow at the air ring, and the larger particles fall back to the grinding disc to continue crushing. When the materials in the air flow pass through the upper separator, they are crushed on the rotor. Under the action of the blades, the coarse particles return to the grinding disc for grinding, and the qualified fine powder comes out of the grinding along with the air flow and is collected by the powder collector of the system. The collected powder is the product ground by the vertical mill. When the iron blocks and other debris mixed into the material move to the edge of the grinding plate, they fall to the lower chamber of the mill and are scraped by the scraper installed at the bottom of the grinding plate into the slag discharge port and discharged out of the machine.
