STM Vertical Mill
Brief Introduction
STM Vertical Mill is a high efficiency and low consumption mill, studied by our numbers engineers, for solving the difficulty of high energy consumption in mill industry. It adopts new grinding principle, reasonable structure, strong bearing do pant materials, and absorbing lots of technical essence of mill, thus our mill’s all performance indicators are over traditional mill’s greatly. Especially, it is very good for crushing high hardness and hardworking materials and it can work under dry or wet condition. Our machine has these characteristics: small metal worn, little dust, simple and firm structure, and easy maintain. It is a revolutionary technical changing in mill industry. It can bring higher economic benefit to customers and it really realized the dream of industrial mill---high efficiency and low consumption. It is the new time for powder making.

Application

Our machine is a high efficiency and low consumption and widely using new grinding equipment. It is mainly used into these areas, such as building, chemical,chemical fertilizer, metallurgy, mining, nonmetal, abrasive, bearing materials, ceramic, steel, thermal power, bricks & tiles, coal industry, etc. It can chemical fertilizer, metallurgy, mining, nonmetal,chemical fertilizer, metallurgy, chemical


fertilizer, metallurgy, mining, nonmetal, abrasive, bearing materials, ceramic, steel, thermal power, bricks & tiles, coal industry, etc. It can grind lump materials into coarse powder (here coarse powder means the mixer of fineness powder, fineness sand, and medium sand.). There are thousands of materials can be grinded by our equipment, and here are some of them and they are just for you consultation. They are cement (raw meal and cement clinker), quartz, feldspar, calcite, gypsum, limestone, dolomite, graphite, fluorite, aedelforsite, phosphate ore, fused calcium magnesium phosphate, carbamide, electrolytic manganese metal, ferromanganese, coal, gangue, slag, zirconium, steatite, granite, orthoclase, marble, barites, ceramics, glass, etc. All the materials whose moth’s hardness is under 9.5 grades 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 the discharge lip.

Technical Advantages

STM Vertical Mill adopts new plaiting and grinding principle and scientific structure, and absorbs numbers of preparing grinding technology. Compared with traditional machines, such as roller mill, fine crusher, plaiting device, kinds of impact mill, it has very remarkable advantages, and it is really realized higher efficiency, lower consumption and environmental protection of preparing grinding technology

1. New design and reasonable structure. Our mill adopts medium speed and pressure, and repeated plaiting principle, and its design is reasonable. The materials fall down by gravity. When the materials are too hard, all the parts of rollers and ring will be worn evenly. The capacity will not reduce greatly. Because of ingenious design, when the unprintable materials such as bolts or pig iron come into machine, they will not make machine worn. It is unnecessary to equip with cyclone and many other pipes, so it needs small space.

2. After materials are grinded by STM Vertical Mill, their physical characteristic is changed 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 and fineness sizes share is large too. When the large materials come 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 device’s 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 adjustable. Expect producing large quantity fineness which is smaller than 100 meshes, this mill also can make materials have large haircuts by numbers of grinded. The max final size is below 3mm, and it is easy for second time grinding.

4. Long service life of easy worn parts and small quantity maintain. The traditional grinding equipments depend on high speed rotation to do forcing crush to materials, and the connection between easy worn parts is direct, so consumption of these parts is fast and high, and large quantity dust, thus adjustment and maintain is frequently, and normal production is influenced. This mill’s grind is grinding to material bed, and roller does both revocation and rotation, thus this avoids direct connection between roller and plate. This is not only improving service life of easy worn parts, but also reducing pollution to materials greatly in the grinding process.

5. This machine has these characteristics: good mechanical property, easy handle, convenient maintain, lower consumption, lower working cost, dry or wet producing; reasonable design, simple structure, easy equipment, lower cost of base building; lower noise and smaller dust with good environmental protection.
