As we all know, the vertical roller mill is one of common powder making machines, it can be widely used in mining, metallurgy, chemistry, cement, construction and other industries. And it can grind hard and soft ores into superfine powder, such as: limestone, gypsum, coal, slag, calcium carbonate and others up to 150 kinds of different stone materials.

When we are using the vertical roller mill, we should to know that the vertical roller mill has a Stronger drying capacity, compare with other grinding mill, it can grind raw materials with moisture content as much as 15%. And there also a advantage is the vertical roller mill has a low noises and little dust, because there is no direct contact between the grinding rollers and grinding disc, so metallic impact is avoided and its noises is 20~25 decibels lower. Totally closed negative pressure operation has employed by this vertical grinding mill, so there is no dust during the operation.

As for the working principle of vertical roller mill is easy to understand, when 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 effiency classsifer.The qualified powder are taken by the air to the powder collector to be collected, while the unqualified powder are sent back for regrinding.

And there are many models of vertical roller mill you can choose, no matter you have a big demand of output or small, such number of vertical roller mills, can help you to solve your trouble.
