Vertical mill Applications:

There are thousands of materials can be ground by our equipment. The typical materials are cement, quartz, feldspar, calcite, gypsum, limestone, dolomite, graphite, fluorite, aedelforsite, phosphate ore, fused calcium magnesium phosphate, carbamide, electrolytic manganese metal, ferromanganese, coal, gangue, slag, steatite, granite, orthoclase, marble, barytes, ceramics, glass. All the materials which are 9 or less on the Mohs scale can be grinded. Working principle:The speed reducer upper on the main machine makes central axis rotate through shaft coupling, and roller hanger rotates with central axis, and rollers on the
hanger roll around the inside of ring. The materials come into inlet from upper side
of machine, and they fall down onto the dispersing materials plate rotating with
central axis in two ways, then the materials are sent into passage between rollers
and rings, after they are grinded into pieces, they are discharged from thedischarge lip. Technical advantages:New design and reasonable structure. Our mill adopts medium speed and pressure, and repeated planishing principle, and its design is reasonable. The materials falldown by gravity. When the materials are high strength and hardworking, all theparts of rollers and ring will be worn evenly, and capacity is compared evenlytoo. Because of ingenious design, when the ungrindable materials such as boltsor pig iron enter into machine, they will not damage the machine. It is unnecessary
to equip with cyclone and many other pipes, so it needs small space.After materials are grinded by STM Vertical Mill, their crystalline structure is
changed and so their grindable structure is improved greatly. The grinded materials
become irregular multiple-unit and their internal crystalline structure arealready broken, the structure of the organization is loose, and the final sizesall have haircuts. Thus, when the materials are grinded in the second time, themachine is mainly doing grinding work not crushing work, so the capacity of second
grinded is improved greatly.The crushing ratio of final products of the grinding mill is high and the percentage of the fineness is high too. When the large materials enter into raymond grinder and through sculptured roller and plate, are grinded into finenesssize by rolling crush, and then they fall down into space between roller and plate,
and form a material bed. Under the spring device's pressure, rollers do numbersflexible extrusion to material bed and make them become fineness, and the result
is very ideal. The fineness of final products can be adjustable. Expect producing
large quantity fineness which is smaller than **0 meshes, this mill alsocan make materials have large haircuts by numbers of grinded. The max final size
is below 3mm, and it is easy for second time grinding.Long service life of wearing parts and less maintenance. The traditional grinding
equipment crush the materials by high speed rotation, and the connection between
wearing parts is direct, so consumption of these parts is fast, and large quantity
dust, thus adjustment and maintain is frequently, and normal production isinfluenced. This grinding mill rollers are grinding to material bed, and do both revolution
and rotation, thus this avoids direct contact between rollers and lining plates.
This is not only improving service life of easy worn parts, but also reducingpollution to materials greatly in the grinding process.
