Vertical Roller Mill is an energy-saving mill equipment that combines mature vertical grinding technology, successful foreign experience and technological innovation and upgrading of our company. It integrates crushing, drying, grinding, grading and conveying, and can be widely used in cement, electric power, metallurgy, chemical, non-metallic ores and other industries, focusing on three major fields of non-metallic ores, coal powder and slag.

The main motor drives the grinding disc to rotate through the reducer, and at the same time, the hot air enters the vertical mill from the air inlet, and the material falls into the center of the grinding disc through the feeding port. When the roller table area is milled, the bulk material is directly crushed by the grinding roller, and the fine-grained material is extruded to form a material bed for inter-particle crushing. The pulverized materials continue to move to the edge of the grinding table until they are taken away by the strong airflow at the air ring. Among the materials carried by the airflow, the larger particles fall to the grinding table again under the action of their own gravity and continue to be pulverized. Then it enters the high-efficiency dynamic separator with the airflow for powder classification. Under the action of the high-efficiency dynamic separator blades, the materials that do not meet the fineness requirements are returned to the grinding disc for grinding, while the materials that meet the fineness requirements pass through the pipeline with the airflow. It enters the pulse dust collector for collection, and is discharged through the discharge device as the finished powder. When the hard-to-grind debris such as iron blocks mixed with the material in the main machine moves to the edge of the grinding table with the material, it cannot be blown up by the wind due to its large weight, and falls into the lower chamber of the grinding machine to be scraped by the scraper installed at the bottom of the grinding table to discharge the slag. After opening, discharge it to the outside of the main unit.
