VM - Vertical Grinding Mill

Large capacity, low consumption, environmentally friendly

VM - Vertical Grinding Mill

VM series Vertical 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 grinding mill is designed and manufactured based on our advanced design idea, in combination with the european technology and the market demand. VM Vertical Roller 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.

Output size : 80-325 mesh

Production capacity : Up to 128TPH(ore mill), up to 50TPH (coal mill)

PROCESSED MATERIALS


Pyrophillite, coal, calcite, barite, limestone, lime powder, marble, silica, talc, kaoline, gold ore, ferrite, clay, slag, marble,and so on.

Motor runs under the condition that speed reducer drives Nether millstone. The materials fall into the center of device through lock air feeder, and hot air comes into mill through air inlet under the function of centrifugal force, the materials when they come by the annular chute. The grinded materials will be taken up by air circulation and the bigger powder will fall down for regrinding. Qualified powders will be collected by collecting device as to be final product. Materials containing water will be dried when they contact with the hot air. Different humidify materials can be dried to the requirement through adjusting the temperature of hot air. Adjusting the separator can get the required fineness powders.
 

APPLICATIONS

Glass fiber industry, coal industry, chemical industry, and for large scale powder making and non mental mine industry.

LM series vertical mill is one advanced mill adopted top technology of domestic and abroad, and based on many years’ mill experience. LM vertical mill can be widely used in such industries as Cement, electric power, metallurgy, chemical industry, non-metallic mineral. It is used to grind granular and materials into powders with required fineness. 

The materials fall into the center of device through lock air feeder, and hot air comes into mill through air inlet under the function of centrifugal force, the materials when they come by the annular chute. ...
 

PERFORMANCE

Features:
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.

SPECIFICATIONS

Mm to inch conversion: 25.4millimeters=1 inch
The humidity and hardness of raw material will affect the fineness and capacity.
