Vertical roller mill has many different forms, but it works basically the same. All of these forms of machine comes with roller (or the equivalent of roller grinding parts), and roller along the track of the disc at the level of circular movement imposed by external grinding roller in the vertical pressure on the disc on the material being the joint action of compression and shear, and to crush.
Material grinding process: motor through reducer rotating drive disc, the material falls from the mill under the central entrance and exit, under the action of centrifugal force to the disc edge by the roller to move and the crushing, grinding out lap after the material was speed up the flow to and vertical mill with one of the separator, after the meal by the separator back to the mill, the re-grinding; powder while grinding out with air, dust collection equipment in the system to collect down, that is, products . Established through the mill in the pneumatic conveying of materials, a larger air flow rate, which can use waste heat of gas, at the same time dry grinding operations.
Vertical Roller Mill Principle
Used in cement grinding production grinding parts of its various forms, there is a cylinder, cone type, ball type, etc., and roller surface is also flat, curved, convex round noodles. Applied to the grinding roller to roller grinding along the track bed in close contact with the material strength of a spring pressure, hydraulic, etc..
How Vertical Roller Mill Works
Vertical roller mill has two pairs of grinding rollers, each pair of roller composed of two narrow rollers, mounted on the same axis and can rotate at different speeds. There are two circular disc slot, and roller to the tire shape, work pressure in the tank. Disc roller and the relative sliding velocity between small and roller can swing, even if the roller sleeve and the disc after the liner wear can guarantee a good abrasive, will not affect the grinding effect. Roller symmetrical structure, one side can be upside down after use and wear. Material grinding process: hydraulic pneumatic roller device through the pressure applied to the material on the crushing of materials, the materials have been moved to crush the edge of disc, from the disc around the nozzle from the exhaust air to improve these materials to Separator.Meal to separate returns after a concentrated mill, fine powder was collected in the precipitator unloading. In the gas flow is small, the meal can not be increased to enhance air flow, they would fall through the nozzle discharged outside the mill, bucket elevator to be transported to the feeder of vertical roller mill, and was re- grinding mill feed people. This cycle features of the way there:
ring by adjusting the air valve, can change the product fineness can Shide mill bed load material uniformity and stability, improving the grinding efficiency;
coarse particles in the external circulation, helps reduce Fan power consumption and overall system power.

Vertical Roller Mill Introduction
LM series vertical mill is devided into two kinds that are coal grinding mills and ore grinding mills, such as vertical roller mill LM130K and vertical roller mill LM240M. As a new kind of large scale power mill, the vertical roller mills are designed specially to solve the problems of low capacity and high consumption of industry grinding mills. Professional grinding mill manufacturer NFLG has manufactured and exported morte and more vertical roller mills to the global world. The vertical roller milling machine is in combination with the European technology based on NFLG advanced design idea.
Vertical Roller Mill is a new kind of large scale power mill which is designed specially to solve the problems of low capacity and high consumption of industry mills. With a decade of years’ research of mills, Vertical Roller Mill is designed and manufactured based on our advanced design idea, and in combination with the European technology and the market demand. It adopts reliable structure and reasonable process flow, integrated with drying ,milling, classifier, elevator. Especially, it 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 series vertical mill adopts reliable structure and reasonable process flow, integrated with drying ,milling, classifier , elevator. Especially ,the vertical roller mills can fully meets the requirement of clients in the high production of powder and its main technical and economy indicator reaches the international level.
Vertical Mill Features and Benefits
1. 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.
2. This vertical roller 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 roller mill can meet requirements with different humidity.
4. LM series vertical grinding 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 Working Principle
The motor dives the grinding table to turn through the speed reducer. At the same time, hot air comes into the vertical roller mill from the air inlet. The materials fall down the centre of grinding table from the feeder . Because of the centrifugal force, the materials move to the edge of grinding table from the centre .The materials are crushed by the vertical roller mill when by pass of the groove on the grinding table. The crusher materials continue to move to the edge of the grinding table until taken away by the airstream. Then the bigger materials fall down the grinding table and the process of crushing continues.
When the materials in the airstream pass the separator on the top of the grinding mill, the materials fall down the grinding table from the taper filler under the force of guide leaf blade. The fine powder comes out with the airstream, and is gathered by the dust catcher of the system. The powder gathered is the final product of vertical roller mill. In the process of the contact of airstream , the materials are dried to meet the clients’ need at the proper moisture. Through the adjustment of the angle between the separator and the leaf of wind’s direction (not suitable to the small type of vertical roller mill), and also the speed of the separator rotor, it can reach the proper fineness of the materials.
