Vertical Roller Mill Working principle
The working principle of a Vertical Roller Mill is as follows: the motor drives the grinding disc through a speed reducer. Material enters the center of the grinding disc through an air lock feeder. Under the action of centrifugal force, it moves toward the edge of the grinding disc and is crushed by the rolling action between the grinding roller and the grinding disc.
The crushed material is lifted by the high-speed airflow at the air ring. The coarse particles fall back to the grinding disc for further grinding, while the fine powder is sent to the classifier for sorting. The qualified fine powder is collected as the product, while the unqualified coarse powder returns to the Vertical Roller Mill for re-grinding.

From Saudi Arabia
"VEST mining equipment revolutionized our Saudi copper mine – handling 50°C desert heat without performance drops. The Arabic-speaking engineering team provided on-site training that cut our ramp-up time by 65%.After 18 months, their durable grinding mill show zero wear in our abrasive conditions. We consider VEST is a reliable partner for GCC mining projects. Would recommend them for friend."

From Indonesia
"VEST has multiple projects in our area. I visited two of them, which gave me greater confidence in handing them over to us. Ultimately, our company purchased a VEST grinding mill production line, and the project passed inspection on the first try."
Jason
From USA
"After switching to VEST mining equipment, our productivity jumped 40% with half the maintenance costs. The German-engineered hydraulic system outperforms competitors in hard rock conditions.What truly impressed us was their 24/7 remote troubleshooting – a game-changer for our Denver iron ore site. Three years of zero unplanned downtime proves VEST’s ‘Built for Decades’ promise."
