Main Structures of Ultrafine Vertical Roller Mill

The CLUM series ultrafine vertical roller mill is a marvel of modern engineering, comprising an array of precision components such as the motor, reduction gear, grinding rollers, grinding plate, pressure-applying device, classifier, mill body, oil station, and an advanced electrical system.

·Grinding Roller
A pivotal component in material crushing and grinding. Lacking direct power input, the rollers achieve rotation passively via friction force upon contacting the materials, ensuring efficient operation. plate turn rotary, the rollers are rotated passively by friction force after touch the materials.

·Grinding Plate
Serving as the primary area for the grinding process, the plate is powered and rotated by the reduction gear, ensuring optimal performance.

·Pressure-applying Device
Crucial for maintaining the pressure between the grinding roller and plate, this device guarantees consistent grinding performance.

·Classifier
Equipped with a multi-rotor classifier, this device separates fine powder with high efficiency and energy conservation, utilizing centrifugal force during the continuous process.


Working Principle of Ultrafine Vertical Roller Mill
 

·grinding process

The core principle of this mill involves the rotation of the grinding plate by the main motor through the reduction gear. Simultaneously, pressurized air enters the mill, carrying materials via a screw conveyor feeder to the center of the rotating plate. Through centrifugal force, materials move outward towards the plate's edge, where large blocks are crushed and reduced to fine particles under the pressure of the grinding roller, ultimately forming a material bed and achieving the desired ultrafine grind through inter-particle crushing.

As the fine powder continues its journey, it is gracefully swept towards the edge of the grinding plate, escorted by the robust air currents at the air ring. As these materials, accompanied by the air flow, ascend through the separator above the grinding plate, the coarse particles are gently redirected back to the grinding plate for a meticulous re-pulverization process. Thanks to the dynamic action of the rotor blade, the fine particles, seamlessly blending with the air flow, effortlessly exit the mill's interior, where they are meticulously collected and elegantly discharged. as a pristine finished powder product, carefully gathered by the powder collector.

·Final product quality guarantee

The coarse granular materials and impurities gracefully descend into the lower grinding chamber, where they are efficiently discharged by the precision-driven scraping plate.
High-precision, multi-rotor classifier with state-of-the-art frequency control, allows for adjustable rotor speeds, producing an array of particle sizes tailored to your needs.
By fine-tuning the hydraulic system pressure, you can adeptly adjust the roller pressure, making it adaptable for materials of varying hardness.
The electronic caging device ensures the crucial safety gap between the roller and plate, effectively mitigating the risk of heavy vibrations due to insufficient feeding.

Technical Advantage of the Ultrafine Vertical Roller Mill

·Remarkably Low Operation Cost
Employ the innovative and durable anti-wear alloy materials in the grinding roller and plate liner. Experience extended service life for wear parts with minimal maintenance. The uniquely designed grinding curves of the roller shell and liner plate facilitate the formation of a stable material bed, ensuring low vibration and high product efficiency.Achieve a productivity that is 20% superior compared to other comparable vertical mills, while realizing a 40% power consumption reduction in contrast to traditional ball mills.

·Elevated Additional Value
The implementation of the multi-rotor classifier allows for the attainment of final particle sizes ranging from D97 5-45 micron, all made possible through the PLC frequency converter control system, enabling the CLUM mill to create 2 micron (20-70%)powder while adapting powder selection patterns to meet diverse client requirements. This significantly amplifies the final powder's added value and broadens its application areas, thanks to the advantages of narrow particle size distribution, uniform particle shape, and controllable 2 micron content.

·Safe and Reliable
With grinding roller pressure being auto-controlled by the PLC/DSC, the system ensures precise pressure management and high efficiency without manual intervention. The roller shell and grinding disc liner plate gaps are safeguarded by both electronic and mechanical caging devices, effectively preventing heavy vibrations and impact. The reducer box and lubricating system are outfitted with multiple inspection and protection devices. Each roller benefits from its own independent lubricating cycle supported by dual pumps, assuring ample lubrication and cooling for the grinding roller's bearings, thereby eliminating excess lubricating oil in the bearing chamber and preventing any leakage. With numerous intelligent protection devices, the CLUM main unit excels in delivering continuous operation characterized by stability, safety, and high-efficiency performance without the need to halt operations.

·Environmentally Friendly
Since the rollers and grinding disc do not directly touch, there is an absence of metal impact noise, resulting in low vibration. Compared to traditional ball mills, the operational noise is 20-25 decibels lower, thereby safeguarding human health from potential harm.

The hermetic seal ensures the entire system operates under a negative pressure environment. The final powder is efficiently conveyed to the final product silo without any dust leakage, ensuring a clean environment that aligns with national environmental protection standards.
