Product Overview of Ultrafine Vertical Roller Mill

As society and economy rapidly advance, the traditional ultrafine powder processing equipment falls short of meeting modern market demands due to its limited capacity. Against this backdrop, leveraging years of expertise in mill manufacturing, Clirik introduces an innovative CLUM series vertical roller mill. By embracing cutting-edge vertical roller mill technologies from Taiwan and Germany, this machine seamlessly integrates functions such as grinding, classifying, conveying, secondary classifying, and packing. Its powder fineness remarkably ranges from 400 to 3000 mesh, overcoming the bottlenecks of traditional systems. Having flourished over a span of 5 years, this breakthrough has led to the installation of over 30 ultrafine powder production lines worldwide.

Application Fields of Ultrafine Vertical Roller Mill

The CLUM series ultrafine vertical roller mill finds versatile applications across the chemical, metallurgy, and non-metallic ore industries. Its ability to excel in processing white superfine non-metallic ore powders makes it invaluable for producing high-grade fillers and additives in papermaking, coating materials, plastics, rubber, PVC, printing inks, and beyond. It serves as a cornerstone for creating ultra-fine dry powders from non-metal materials like calcite, marble, limestone, dolomite, barite, talc, kaolin, wollastonite, gypsum, feldspar, pyrophyllite etc.
 

Main Structures of Ultrafine Vertical Roller Mill

The CLUM series ultrafine vertical roller mill comprises key components such as the motor, reduction gear, grinding rollers, grinding plate, pressure-applying device, classifier, mill body, oil station, and electrical system, each playing a crucial role in its operation.

·Grinding Roller
This essential component crushes and grinds materials. It operates without power input while the grinding plate rotates, as the rollers are passively driven by friction when they contact the materials.

·Grinding Plate
Functions as the principal area for the grinding process, rotating and being driven by the reduction gear.

·Pressure-applying Device
Maintains the optimal gap and pressure between the grinding roller and plate, ensuring efficient operation.

·Classifier
A multi-rotor classifier that uses centrifugal force to separate fine powders continuously. It is designed to be an energy-efficient and highly effective powder separation device.


Working Principle of Ultrafine Vertical Roller Mill
 

·grinding process

Driven by the main motor via a reduction gear, the grinding plate rotates. Simultaneously, high-pressure air is directed into the mill's interior through the air inlet. Materials are delivered to the center of this rotating plate by a screw conveyor feeder. Due to centrifugal force, they spread evenly from the center to the edge of the plate. As they traverse the plate's track, larger material blocks are directly crushed and ground by the grinding roller. The resultant fine particles form a material bed, facilitating inter-particle crushing that continues until a fine powder is achieved.

As the fine powder journeys gracefully towards the edge of the grinding plate, it is elegantly swept away by the powerful airflow at the air ring. When materials, accompanied by this airflow, traverse the separator positioned above the grinding plate, the coarser particles are expertly directed back for a refined re-pulverization process. Thanks to the precise action of the rotor blade, fine particles are smoothly escorted out of the mill, along with the airflow, to be meticulously collected and discharged. These fine particles are transformed into a finished powder product by the advanced powder collector.

·Final product quality guarantee

Coarse granules and impurities are expertly guided to fall into the lower grinding chamber, where they are efficiently discharged, ensuring a clean process, by the diligent scraping plate.
Our high-precision multi-rotor classifier, featuring sophisticated frequency control and adjustable rotor speed, artfully produces a wide range of particle sizes, catering to diverse needs.
By skillfully adjusting the hydraulic system pressure, the roller pressure can be finely tuned to accommodate materials of varying hardness.
An innovative electronic caging device ensures a safe gap between the roller and plate, effectively preventing heavy vibrations due to insufficient feeding.

Technical Advantage of the Ultrafine Vertical Roller Mill

·Cost-Effective Operations
Utilizing a unique anti-wear alloy, our materials for grinding rollers and plate liners are crafted for longevity. The specialized design of the roller shell and liner plate grinding curves fosters a stable material bed, minimizes vibration, and maximizes efficiency. It operates20% higher in capacity than comparable vertical mills while saving 40% energy compared to ball mills.

·Superior Additional Value
With the multi-rotor classifier, achieving a final particle size for D97 5-45 microns is possible. The PLC frequency converter control system in the CLUM mill allows production of 2-micron (20-70%)powder while adjusting powder selection patterns according to diverse client needs. This significantly enhances the final powder's added value and expands application areas, thanks to the advantages of uniform particle size distribution and controllable 2-micron content.

·Safe & Reliable
The grinding roller pressure, precisely controlled by the PLC/DSC, ensures effective grinding with high efficiency without manual intervention. The roller shell and grinding disc liner plate gap are securely protected by both electronic and mechanical caging devices to prevent excessive vibration and impact. The reducer box and lubrication system feature multiple inspection and protection devices. Each roller has its own independent lubrication cycle with dual pumps. This guarantees ample lubrication and cooling of the grinding roller bearings, preventing excess oil in the bearing chamber and eliminating leakage risks. Equipped with advanced protection devices, the CLUM main unit consistently delivers stable, safe, and high-efficiency performance, allowing for uninterrupted operation.

·Eco-Friendly
The roller and grinding disc operate without direct contact, minimizing metal impact noise and ensuring low vibrations. Compared to ball mills, the operating noise is 20-25 decibels lower, safeguarding human health.

A sophisticated hermetic seal guarantees system operation under negative pressure, ensuring that the final powder is transported to the product silo without dust leakage, thus maintaining a clean environment that complies with national environmental protection standards.
