  • Working principle

Vertical Roller Grinding Mill is a kind of large scale powder mill which is designed specially to solve the problems of low capacity and high consumption of industry mills. With a decade of research of mills, vertical roller grinding mill is designed and manufactured based on our advanced design idea, in combination with the european technology and the market demand. Clirik Vertical Roller Grinding Mill adopts reliable structure and reasonable process flow, integrated with drying, milling, classifier, elevator. Especially, it can fully meet the requirement of clients of the high production of powder, and its main technical and economic indicator reaches the international level.

 1. Low operating costs

Combine the crushing, grinding,dring, classifier and elevator , the system of vertical mill is simple and occupation area is about 50% of ball mill system. It can be installed outside, so it will reduce a large number of investment cost;

2. High efficiency
Compared with ball mill, vertical mill can save energy consumption 30%-40%;
3. Less wear and tear
The optimized roller and the high quality raw material make the machine’s life more longer;
4. High dring ability
As the hot air inside contacts directly with the material, drying ability is higher, and it saves energy. By regulating the air temperature, it can meet requirements with diffirent humidity;
5. Simple and reliable operation
Automatic control system is equiped, so the remote control makes it easy to operate. It is equipmented with one device,which prevents the roller from contacting with the liner directly, and avoids the destructive impact and severe vibration;
6. Convenient maintenance
By reparinging fuel tank, rotating the arm, it is fast to replace the roller sleeve, and liner, and reduce the downtime loss;
7. Environmental protection
It is with small vibration, low noise, and the overall sealing. The system works under negative pressure, so there is no dust going out. It meets the requirements of the state Environmental Protection.

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.
