Technical Advantages:

1. New design and new structure. Our mill adopts medium speed and pressure, repeated plaiting principle, and its design is unique in mill industry. The materials fall down by the force of gravity. When the materials are too hard, all the parts of rollers and ring will be worn evenly. So the capacity will not change greatly. Because of this ingenious design, when the unprintable materials, such as bolts, pig iron, etc, come into machine, they would not worn machine. Because it is unnecessary to equip with cyclone and many other pipes, small space it will take.
2. After materials are grinded by STM Vertical Mill, their physical characteristic is changed greatly and so their grind able characteristic is improved greatly. The grinded materials become irregular multiple-unit, and their inside lattice are already broken. The structure of the organization is loose, and the final sizes all have haircuts. Thus, when the materials are grinded for the second time, the machine is mainly do grinding work not crushing work, so the capacity of second grinded is improved greatly.
3. The crushing ratio of final products of STM Vertical Mill is large. So is the fineness size. When the large materials are put into STM Vertical Mill and through sculptured roller and plate, they are grinded into fineness size by rolling crush, and then they fall down into space between roller and plate, and form a material bed. Under the spring devices pressure, rollers do numbers flexible extrusion to material bed and make them become fineness, and the result is very ideal. The fineness of final products can be adjusted. Expect producing large quantity fineness which is smaller than 100 meshes, this mill also can make materials, which have large haircuts, by numbers of grinded. The max final size is below 3mm, so it is easy for second-time grinding.
4. Long service life of easy worn parts and small quantity maintain. Depending on high speed rotation, the traditional grinding equipments do forcing-crush to materials, and the connection between easy worn parts is direct. Therefore the consumption of these parts is fast and high. Also there are large numbers of dusts. As a result, adjustment and maintenance is frequent, and speed of production is influenced. This mills grind drove to the material bed, which located between plates and rollers, thus this avoids direct connection between roller and plate. Not only can this improve service life of easy worn parts, but also can reduce pollution to materials greatly in the grinding process.
