As we all know that the vertical roller mill is one of the most common use stone powder making machine, can be used in more than including cement, slag and other more than 300 kinds of hard stone minerals powder grinding. And compare with the common stone powder grinding mill, the vertical roller mill can be divided into three grade:
First grade: 600-1250 mesh (common method grinding);
Second grade: 1250-3000 mesh (after second classify);
Third grade: above 3000 mesh (after second classify and grinding by wet method, the minimum powder size even can up to 10000 mesh).

As for the working principle of the 3000 mesh vertical roller mill as following:

The grinding disc is driving by motor through reducer. The material falls to grinding disc from the feed opening. The materials are driven to the edge of disc by the centrifugal force and crushed into fine powders by rollers. Then, the hot air from the nozzle take the fine powder to high efficiency classify.The qualified powder are taken by the air to the powder collector to be collected, while the unqualified powder are sent back for regrinding.
