LM vertical grinder mill is a large capacity grinder equipment developed by advanced experts of Liming. Vertical grinder mill is one advanced mill, adopting top technology domestic and abroad, and based on many years’ mill experiences. It can crush, dry, grind, and classify the materials.LM series vertical milling machine can be widely used in such industries as cement, power, metallurgy, chemical industry, non-metallic mineral. It is used to grind granular and powdered materials into powder with required fineness.
Vertical grinder mill is widely used in construction, chemical industry, metallurgy, mineral, steel and electric power industry, and it can process hard materials such as cement, quartz, feldspar, calcite, gypsum, limestone, dolomite, phosphate rock, coal, coal gangue, slag, zircon sand, talc, granite, orthoclase, marble, barite, ceramics, glass
LM vertical grinder mill is specially used in following areas:
1)Large production of the coal industry, coal gangue powder production;
2)A variety of chemical raw materials of chemical industry production powder production;
3)A variety of non-metallic minerals industry, the production of hundreds of medium and high hardness of ore large-scale powder preparation;
4)Dedicated large production of coal and gangue powder production;
5) Special steel slag and blast furnace slag grinding;
6)A variety of non-metallic minerals industry, the production of hundreds of medium and high hardness of ore large-scale powder preparation;
7)Dedicated power plant desulfurization limestone grinding;
Main Advanced Features:
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
⑴ 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%.
⑵ 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 different humidity.
4. Simple and reliable operation
⑴ It is equipped with automatic control systems, so remote control makes it easy to operate.
⑵ It is equipped 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 repairing 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.
