Grinding rollers and discs are made of highly wear-resistant materials, with long service life and low maintenance costs.
The grinding zone between the grinding roller and the grinding disc adopts a special grinding curve design to ensure the stable operation of the host and effective grinding.
The pressure of the grinding roller adopts a hydraulic tension rod with adjustable elastic coefficient to ensure the continuous pressure of the grinding roller on the material.
he grinding roller and the grinding disc are not in contact, and the mechanical limit device is adopted to avoid damage, impact and vibration.
The multi-rotor high-efficiency cage powder separator has high powder separation efficiency and is easy to adjust and control, and can quickly produce a variety of finished products.
The diatomite powder ultrafine vertical roller mill grinding disc is driven by a motor through the reducer.
The materials fall into the center of the grinding disc through the elevator, screw conveyor, star-shaped feeding valve, and feeding screw, and move to the edge of the grinding disc under the action of centrifugal force. When passing through the grinding zone between the grinding roller and the grinding disc, it is crushed by the pressure of the grinding roller and the shearing force between the grinding disc and the grinding roller.
The pulverized material continues to move to the edge of the grinding disc until it is brought into the multi-rotor powder concentrator at high speed by the airflow from the high-pressure fan on the edge of the grinding disc for classification.
The powder that does not meet the requirements falls into the grinding disc and re-grinds. The powder that meets the requirements is collected by the airflow into the dust collector, and sent to the finished product warehouse by the lifting system or the pneumatic conveying system.
Diatomite powder ultrafine vertical roller mill are suitable for huge capacity producing, widely used in grinding non- flammable and non-explosive materials under 6 (the Moh’s hardness), such as Bamboo, gypsum, calcium carbonate, quartz, feldspar, calcite, talcum, barite, fluorite, iron ore, copper ore quartz, especially for slag, cement clinker, zircon sand, fly ash and carborundum, coal, etc.
Diatomite powder ultrafine vertical grinding mill can be widely applied in the industries of chemicals, metallurgy, non-metallic ores etc. In particular, it is outstanding in processing white superfine non-metallic ore powders, providing superior quality fillers and additives for paper making, coating materials, plastics, rubber, PVC, printing ink etc.
1. Low Operation Cost.
Use the special anti-wear alloy materials for grinding roller and plate liner. Long service time for wear parts, low maintenance. The grinding curves of the roller shell and liner plate are uniquely designed, easy to form the stable material bed, low vibration, high product efficient. It is 20% higher than other equivalent vertical mill in capacity, saving 40% powder consumption compared with ball mill.
2.High Additional Value
Adopting the multi-rotor classifier, the final particles size for D97 5-45 micron are attainable. Equipped with the PLC frequency converter control system, the diatomite powder ultrafine vertical grinding mill can produce 2 micron (20-70%) powder and adjust powder selection patterns according to client’ different requirements. It has greatly increased the final powder added value and application areas due to the advantages of narrow particle size distribution, unit form particles shape and controllable 2 micron content.
3. Safe And Reliable.
The pressure being applied to the grinding roller auto-controlled by the PLC/DSC enables the accurate control of grinding pressure and highly efficient without manual operation; the roller shell and grinding disc liner plate gap is dual protected by electronic and mechanical caging devices to avoid the heavy vibration and impact. The reducer box and lubricating system are equipped with multiple inspection and cycle with double pumps.
The sufficient lubrication and cooling of the bearings for the grinding roller is ensured therefore no excess of lubricating oil in the bearing chamber and no leakage could occur. equipped with multiple intelligent protection devices, the diatomite powder ultrafine vertical roller mill main unit can realize the continuous operation with stable, safe and high-efficient performance rather than stop running.
4. Environmental Friendly.
Product Advantage of diatomite powder ultrafine vertical roller mill and grinding disc do not touch each other directly, there does not have the metal impact noise in low vibration, compared with ball mill the running noise is 20-25 db lower which would not hurt human’s health. Hermetic seal ensures that the system operates under negative pressure.The final powder is conveyed to the final product silo without dust leakage. The environment is clean, meeting the national environmental protection requirements.
