The LM Series Vertical Mill,which is China patent product owning advanced international technology, is our latest grinding machine, which is designed by our expert in grinding equipment with great concentration, on the basis of a long time' producing practice , And it opens an industrial grinding new time with high efficiency and low energy consumption.

The LM Series Vertical Mill is on purpose to grind mining materials in the fields of metallurgy, building materials, chemistry, mining and so on. The Roller Mill 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, chrome green, gold mine, red mud, clay, kaolin, coke, gangue, porcelain clay, cyanite, fluor, bentonite, maifanshi stone, liparite, muddy green rock, pyrophyllite, redware rock, basalt, gypsum, graphite, Carborundum, heat insulator.

Feature Of The LM Series Vertical Mill:

Consumption saving;High efficience ;High using rate ;Accident insurance ;Well using against high hardness and hard-process material ;Wet production ;Occupation of area is small.

Working Principle And Main Structure Of The LM Series Vertical Mill:

The system consists of main unit, blower, cloth dust cleaner and pipes.The working principle is as follows. The central axle is rotated by motor. The roller suspender is connected with the bottom of the axle. The roller setting is set on the suspender. The roller suspender not only rotates with central axle, but also rotates under the friction of ring. The materials fall down from the hopper on the top of the machine to the clearance between roller and ring. Under the extrusion of the centrifugal force, materials will be crushed to pieces. The crushed materials will discharge naturally from the discharging valve. When the mill is working, blower will attract hot air in the mill and the cold air outside will swarm into because of negative pressure. So the heat coming from the working procedure will be taken away, which will lengthen the lifetime of the bearing and other spare parts. The air taken by the blower is sent into cloth dust cleaner, which will collect the fine powder. The purified air is discharged into the atmosphere.When the system is working with wet method, blower and dust cleaner are not necessary.

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.
