Vertical Roller Grinding Mill For 200--3000 Mesh Powder With Round Powder Shape
This vertical roller mill is equipped with 5 motors classifier, which can produce micro powder/ultrafine powder with a fineness range of 325 mesh to 3000 mesh. This vertical rollers mill has features of power-saving, round powder shape, higher output, easy installation and maintainance, lower investment and stable performance. And this vertical mill is increasingly accepted by customers to produce ultrafine powder.
Some countries also produce this kind of ultrafine vertical roller mill, such as Japan, Germany, USA, Italy and Taiwan. But their price is much higher and production need a long time of about 12 months. The delivery time in our company can guarantee 90 word days, which can be installed early in buyers' factory. The powder produced by this vertica roller mill has features of strengthening, transparency, dispersion, thixotropy and floating.
This hydraulic station plays a very important role in the whole vertical roller mill system. This vertical roller mill hydraulic drive system control oil line adopts the new integrated valve self-produced by our company. The design of integrated valve complies with GB3766-87 (Hydraulic System General Technical Conditions) in the technical requirements. Its excellent design and high-precision internal processing, supplemented by external control components with stable performance and air cooling system, providing a substantial increase in the accuracy and stability of the work.
At the same time, the hydraulic station compact design simplifies the hydraulic circuit and pipeline, eliminating the mechanical friction oil leakage, facilitating assembly and the user's daily maintenance.
The vertical roller mill hydraulic system system pressure can be adjusted. System pressure is controlled by the relief valve. The clockwise adjustment of the handle of relief valve is to increase the pressure, while anti-clockwise adjustment is to decrease the pressure. According to the actual use of the pressure to adjust the system pressure to 0.7MPa ~ 8.1MPa, locking adjustment screw, and observe the system piping with or without leakage and abnormal sound.
Working Principle of Vertical Roller Mill:
The reducer makes the grinding table rotate. The crushed calcium carbonate conveyed to the grinding house by belt conveyor or screw conveyor falls down onto the grinding table because of gravity. With help of the centrifugal force of the rotating grinding table, calcium carbonate move from center to edge. And at the same time, calcium carbonate is ground between roller and ring. After being ground, the fine powder goes through the classifier into the pulse-jet collector with the help of air blower sucking. Coarser material will fall down to the mill again due to its large self-gravity and get reground.
The Advantages of Vertical Roller Mill:
1. Wide powder fineness range: calcium carbonate ultrafine roller grinding mill use turbo air classifier, which can produce a wider range of powder sizes. There are 30%~70% in the 2μm range, D97=4~45μm; the specific surface area is 21000 cm²/g, while products with D97=8.5μm can be directly produced by the mill.
2. Lower power consumption
3. The powder produced by ultrafine vertical roller grinding mill has a narrow particle size distribution, control gap of 2μm powder content, high profit margins and added value.
4. After being improved, rollers, grinding table, diversion systems and internal circulation systems can greatly improve the grinding efficiency and increase output by 15%~30% compared to the same type of domestic products.
5. Lower vibration and lower noise
6. Environment-friendly and 99.99% of the powder can be collected.
7. Automatic control with PLC system
