STM Vertical Mill

Product Description

STM Vertical Mill Technical Advantages:
1. Outstanding design.
2. High productivity.
3. High reduction ratio
4. Long service time
5. Environmental protection

STM Vertical Mill Features:

1) It adopts new grinding principle, reasonable structure, strong bearing dopant materials, and absorbs lots of technical essence of other mill; It is very good at processing high hardness materials under dry or wet conditions

2) Application: 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 calciummagnesium 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

3) Technical advantages:

A) New design and reasonable structure; Our mill adopts medium speed and pressure, and repeated planishing principle, and its design is reasonable; The materials fall down by gravity; When the materials are high strength and hardworking, all the parts of rollers and ring will be worn evenly and capacity is compared evenly too; Because of ingenious design, when the ungrindable materials such as bolts or 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

B) 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 are already broken, the structure of the organization is loose, and the final sizes all have haircuts; Thus, when the materials are grinded in the second time, the machine is mainly doing grinding work not crushing work, so the capacity of second grinded is improved greatly

C) The crushing ratio of final products of STM vertical mill is high and the percentage of the fineness is high too; When the large materials enter 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; Except 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

D) Long service life of wearing parts and less maintenance; The traditional grinding equipments 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 is influenced; This mill's rollers are grinding to material bed, and do both revolution and rotation, thus this avoids direct contact between rollers and lining plates; This not only improves service life of easy worn parts, but also reduces pollution to materials greatly in the grinding process

4) Model: STM86, STM125
