STM Vertical Mill-zenith
Applications:There are thousands of materials can be ground by our equipment. The typicalmaterials are cement, quartz, feldspar, calcite, gypsum, limestone, dolomite,graphite, fluorite, aedelforsite, phosphate ore, fused calcium magnesiumphosphate, carbamide, electrolytic manganese metal, ferromanganese, coal,gangue, slag, steatite, granite, orthoclase, marble, barytes, ceramics, glass. Allthe 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 throughshaft coupling, and roller hanger rotates with central axis, and rollers on thehanger roll around the inside of ring. The materials come into inlet from upper sideof machine, and they fall down onto the dispersing materials plate rotating withcentral axis in two ways, then the materials are sent into passage between rollersand 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 unnecessaryto equip with cyclone and many other pipes, so it needs small space.After materials are grinded by STM Vertical Mill, their crystalline structure ischanged and so their grindable structure is improved greatly. The grinded materialsbecome 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 secondgrinded is improved greatly.The crushing ratio of final products of STM Vertical Mill is high and the percentageof the fineness is high too. When the large materials enter into STM VerticalMill, and through sculptured roller and plate, they 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 resultis very ideal. The fineness of final products can be adjustable. Expect producinglarge quantity fineness which is smaller than 100 meshes, this mill alsocan make materials have large haircuts by numbers of grinded. The max final sizeis below 3mm, and it is easy for second time grinding.Long service life of wearing parts and less maintenance. The traditional grindingequipment crush the materials by high speed rotation, and the connection betweenwearing parts is direct, so consumption of these parts is fast, and large quantitydust, thus adjustment and maintain is frequently, and normal production isinfluenced. This mill`s rollers are grinding to material bed, and do both revolutionand 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.Main technical parameters:1) Model: STM1252) Inlet size (mm):3) Final size (mm): 3 - 0.0444) Capacity (MT/h): 15 - 555) Power of main motor (kW): 90 - 1106) Overall size (mm): Φ2,300 x 5,600
