Vertical roller mill

SBM Grinding Mills widely used in metallurgy, building materials, mining minerals in areas such as grinding materials processing. According to the fine grinding of materials and discharging materials fineness, milling machines can be divided into raymond mill powder machine, high pressure hanging roller mill grinding machines, high pressure powder grinding mill, through centrifugal mill overpressure trapezoid mill, tricyclic in the six-speed milling machine types.

LM series vertical roller mill machine is based on advanced home and abroad technology, combine with years of experience in the production of grinding machine. The LM series vertical grinding machine is an ideal equipment that integrates crushing, grinding

Vertical roller mill technical features

1. LM series vertical roller 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 roller 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.

Vertical roller mill application

Vertical roller mill are mainly applied to proceed the powder crushing manufacturing of the materials such as calcite, limestone, light dry stone coal, barite, fluorite, glaze, slag, wollastonite, kaolin, vermiculite, mica, feldspar, brucite, spores, potassium salt slag, garnet , quartz,etc.And the Vertical roller mill can also be used to the non-metal mining areas with the Mohs hardness of less than 7degree ,such as mining metallurgy, chemical industry, electronics, medicine, food, daily chemical, agricultural, building ,and so on.

Vertical roller mill working principle

Flow of material through the Vertical roller mill of the separator when,the motor wil drive the plate to rotate by the reducer and then the materials will fall down on the central place of the plate from the inlet by the qir-locking feeder .While at the same time ,the hot air will enter the grinder from the air inlet.With the rotation of the plate ,the materials will move to the edge of the plate by the centrigugal force and the materials will received the pressure from the roller and be crushed when it passes the circle ring sink on the plate..And the coarse powder will fall down from the cone hopper and then repeat this kind of process when materials in the air stream passes the upper seperator by the effect of the rotors.And during the process ,the fine powder will flow out with the air stream .By the dust catcher ,the final products will be collected .The materials with moisture will be dry when it contact with the hot air stream.By adjusting the temperature of the hot air,we can satisfy materials with various moisture degree ,thus achieving the required products moisture.By the seperator ,we can also achieve the required coarse and fine degree of the products .
