The motor dives the grinding table to turn through the speed reducer. At the same time, hot air comes into the roller mill from the air inlet. The materials fall down the centre of grinding table from the feeder. Because of the centrifugal force, the materials move to the edge of grinding table from the centre .The materials are crushed by the grinding roller when by pass of the groove on the grinding table. The crusher materials continue to move to the edge of the grinding table until taken away by the airstream.
Then the bigger materials fall down the grinding table and the process of crushing continues. When the materials in the airstream pass the separator on the top of the mill, the materials fall down the grinding table from the taper filler under the force of guide leaf blade. The fine powder comes out with the airstream, and is gathered by the dust catcher of the system. The powder gathered is the final product of roller mill. In the process of the contact of airstream , the materials are dried to meet the clients ’ need at the proper moisture. Through the adjustment of the angle between the separator and the leaf of wind’s direction (not suitable to the small type of vertical mill), and also the speed of the separator rotor, it can reach the proper fineness of the materials.

1. LM series vertical mill can crush, dry, grinding, classifying, so the system is simple, and occupation area is about 50% of ball mill system. In addition, it can be installed outside, so LM vertical mill will reduce a large number of investment costs.
2. Roller of this series vertical mill compacted materials directly onto the grinding disc, so power consumption is low.
3. As the hot air inside contacts directly with the material, drying ability is higher, and it saves energy. By regulating the air temperature, this series vertical grinding mill can meet requirements with different humidity.
4. LM series vertical mill is equipped with automatic control systems, so remote control makes it easy to operate.
5. When the material stays in the mill for a short time, vertical mill is easy to detect and control the product particle size and chemical composition, to reduce duplication of milling, stable product quality.
6. In addition to the above advantages, our vertical roller mill also has the following advantages: maintenance convenience, environmental protection and so on.

LM series vertical grinding mill is the newest grinding machine, which integrates the advanced international technology and years of mill-producing experience . It is an ideal equipment that integrates crushing, drying, grinding and grading conveyor all together.

LM series vertical grinding machine can be widely used in cement making, power,metallurgy, chemical and nonmetalliferous ore industries. It is used to grind lumpy, granular and powdery materials to the required size.

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.

Note: This specification is just reference, any changes are subject to the Vertical Mill products.

1. Low Investment Cost
This mill itself can crush, dry, grinding, classifying, so the system is simple, and occupation area is about 50% of ball mill system. In addition, it can be installed outside, so it will reduce a large number of investment costs.

2. Low Operation Cost
High efficiency: roller compacted materials directly onto the grinding disc, so power consumption is low. Compared with ball mill, it saves energy consumption by 30% ~ 40%.
Less wear and tear: As the roller is not in direct contact with the disc, and material of the roller and liner is high quality, so life lime is long.

3. High Drying 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.

4. Simple and reliable operation
It is equipped with automatic control systems, so 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.

5. the stability of product quality
As the material stays in the mill for a short time, it is easy to detect and control the product particle size and chemical composition, to reduce duplication of milling, stable product quality.

6. Maintenance convenience
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.
