VM series Vertical Mill

About VM Series Vertical Mill:

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

Features and benefits:

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. Vertical roller mill 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. Vertical roller mill 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.
Vertical roller mill 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. 

Application of VM Series vertical grinding Mill:

VM Series vertical grinding machine is the ideal substitute of the traditional grinding mills like Raymond grinding mills, high pressure suspension grinding mills, ball mills, etc. Nowadays, Shibang vertical grinding mills have been widely used in cement, power,metallurgy, chemical and nonmetalliferous ore industries. The VM Series vertical grinding machine is widely used to grind lumpy, granular and powdery material to the required size.

 Working principle of VM Series vertical grinding mill:

The motor drives the grinding table through decelerator. The materials fall down the center of grinding table from feed opening. At the same time, hot air comes into the mill from the air inlet. Due to the centrifugal force, materials move to the edge of the grinding table. The materials are pulverized by the roller when by pass of the groove on the grinding table. The crushed materials are brought up by vane high-speed airstream, the larger particles fall down to the grinding table for regrinding. When the materials in the airstream pass the separator on the top of the mill , the coarse powder fall down the grinding table for regrinding under the function of rotation rotor. The fine powder comes out with the airstream,and is gathered by the dust catcher. The materials content with moisture will be dried when they meet the hot airstream. Through adjusting the temperature of the hot airstream, it can meet different material’s requirement, and also through adjusting seperator, it can reach proper fineness of materials.
