LM Vertical Mill’s Introduction
LM series vertical roller mill is one advanced mill, adopting top technology domesic 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.
LM Vertical Mill Main Features and Benefits
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.

Note:
1. Input material should be brittle material with Mohs hardness not more than seven.
2. Hot air is needed only when there is a requirement that water percentage of final product should be less than raw material.
3. If the material is hard to grind, motor power take large value.
