Application Of STM Vertical Mill:

The STM Vertical Millis on purpose to grind mining materials in the fields of metallurgy, building materials, chemistry, mining and so on. 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, 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.

Working Principle and Main Characteristic Of STM 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.

The Operation Rules of the Pulverizer:

Before the machine is started, check whether all the maintenance doors are closed tightly and there is iron or so. Pay attention to the turnaround, the right of which is clockwise dextrorotation when looking down the main axle.
1. Turn on the blower.
2. Turn on the motor of the mill. Feed materials until the motor is under normal condition.
3. When turn off the mill, please wait until the material in the mill is out. Turn off the hopper first and motor of the mill. Turn off the blower in the end.
4. In order to guarantee the production safety, the pulverizer must not be oiled under the normal working condition. If any part of the machine generates abnormal noises, or the load is suddenly raised up, turn off the machine immediately for checking and troubleshooting to avoid serious accidents. Before restarting the machine, take out the residual material first. Otherwise the current will be too strong to affect the start.
5. If the production goes with wet method, the operation rule refers to the above for there are no blower and dust cleaner.
6. The above instruction is as dry wet an example. Wet method conforms to the principle of simplicity.
