When people want to know about a kind of equipment,the first question they asked is its working principle.Well,this text will introduce vertical roller mill's working principle.
The main motor drives the grinding disc to rotate through the reducer, while the hot air enters the grinding body from the air inlet, and the material falls into the center of the grinding disc through the inlet port. Under the action of centrifugal force, the material moves evenly from the center of the grinding disc to the edge. 
When passing through the grinding roller area on the grinding disc, it is crushed by the grinding rollers, and the bulk materials are crushed directly, while fine materials are crushed to form a bed for intergranular crushing. After crushing by vertical roller mill, the material continues to move towards the edge of the grinding disc until it is carried away by the strong air flow in the wind ring.
In the material brought by the air flow, the larger particle material falls back to the grinding disc under the action of its own gravity and continues to crush.The other materials enter the high-efficiency dynamic separator with air flow for powder classification. Under the action of the blade of the high-efficiency dynamic separator, the materials that do not meet the fineness requirements are returned to the grinding disc for grinding. The materials that meet the fineness requirements are collected in the pulse precipitator with air flow through the pipeline and discharged through the discharging device as finished powder.
If the material containing iron block is mixed into the main machine of vertical roller mill, when it moves to the edge of the mill disc, it cannot be blown up by wind because of its heavy weight. When it falls into the lower chamber of the mill, the scraper installed at the bottom of the mill disc is scraped into the slag discharge port and discharged from the outside of the main machine.
