Vertical roller mill Is a kind of crushing equipment featuring high-efficient and energy-saving. And Vertical roller mill have integrated the crushing and grading into a single whole , which have satisfied the various requirements of the customers and materials. And at the same time , we company also have the super thin grinding mill of Vertical roller mill ,which have been catogrized as the new &high energy-saving products in the eight fifth period by the national cement development center . It can grind the non-flammable and non-explosive mineral materials with the Moh’s hardness lower that scale 9.5 such as quartz, feldspar, calcite, talcum, barite, fluorite, rare earths, marble, ceram, bauxite, manganese ore, iron ore, copper ore, phosphate rock, colcothar, zircon, slag, cement clinker, acticarbon, dolomite, beresite, garnet, iron oxid yellow, bean cake, chemical combination, compound fertilizer, fly ash, soft coal, charred coal, lignite, magnesite and so on.

Vertical Roller Mill Technology Advantages:
1. Low invest cost
2. Low run cost
3. High drying ability
4. Easy to operate, reliable performance
5. Stable quality
6. Convenient to maintain
7. Environmental protection

Working Principle of Vertical Roller Mill:
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.The crushed materials will be brought away by the high speed air and the big size will fall down on the plate and be reginded .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 .

Vertical Roller Mill Technical Data:

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.

Note: If there is any modification,all parameter and overall dimension are subject to the operating instructions.
