[ LM Vertical Mill Overview
]
LM series vertical mill is the newest grinding machine of vertical mill professional manufacturer-SBM, which is designed specially to solve the problems of low capacity and high consumption of traditional industry mills. With a decade of years’ research of mills, our vertical mill is designed and manufactured based on advanced design idea, and integrates the advanced international technology and years of mill-producing experience.
LM series vertical mill adopts reliable structure and reasonable process flow; it is ideal equipment that integrated with drying, milling, classifier, and elevator. Especially, this vertical mill can fully meets the requirement of clients in the high production of powder and its main technical and economy indicator reaches the international level.
[ LM Vertical Mill Application
]
LM series vertical mill can be widely used in cement making, power,metallurgy, chemical and nonmetalliferous ore industries. This series vertical grinding mill used to grind lumpy, granular and powdery materials to the required size.

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.

LM Vertical Mill Operation and Maintenance
]
1, When the vertical roller mill working, you should observed the wind speed and input air, and they can not be too small.
2 Good control of material layer. If the material layer is too thick or too thin, it will cause the vertical mill shock.
3 The grinding materials can not have too large metal.
4 Keep the vertical mill’s main motor electric current and pressure gage steady.
