As a new type of ultrafine grinding equipment, the LUM ultrafine vertical mill integrates powder grinding, separation and transportation. With years’ experience in mill production, the LUM ultrafine vertical roller mill are designed by our company, basing on vertical mills, we introduce Taiwan’s grinding roller technology and Germany powder separating technology. As a professional medium and high-end processing equipment in plastic master batch, PVC, artificial stone, electric cable, non-woven fabrics and other industries，LUM Series LUM Ultrafine Vertical Mill is mainly used for the ultrafine grinding of calcite, marble, limestone, talc, dolomite, barite, kaolin, wollastonite, gypsum, feldspar, pyrophylite and other non-metallic mineral ores.
The grinding curves of the roller shell and lining plate are uniquely designed based on the ultrafine pulverization principle, which makes it easier to form material bed, improving the grinding efficiency and increasing the proportion of finished products from the primary grinding.
The principle of multi-rotor powder classifiers is adopted, so the finished product fineness can be customized as selected range , with no low-grade material in existence. By adopting PLC control system, major parameters like grinding pressure, rotating speed of grinding disc and speed of classifier etc.
The control mode for pressure adjustment of grinding roller adopts PLC/DCS automatic control system, which ensures the accurate control of grinding pressure, high efficiency and stable operation. Automatic control system enables remote control and simple operation. Frequency-conversion speed regulation enables the mill to be used for materials.
Special structural design and operating principle of the mill ensure small vibration and low noise. The whole equipment is well sealed and the system operates under negative pressure. Therefore, powder and dust are prevented from flowing out of the system. It is environmentally-friendly and meets the national environmental protection requirements.
Materials are delivered to the center of the grinding plate by the screw feeder. Driven by the reducer, the rotating plate generates centrifugal force, making materials spread outward evenly.
In the grinding zone, large lumps are directly crushed by rollers, while fine particles form a material bed for inter-particle grinding. Processed materials are carried by airflow into the classifier. Off-spec particles return to the plate for regrinding, and qualified powder is collected by the pulse dust collector as final products.
Impurities like iron blocks move to the plate edge by gravity, drop into the lower chamber, and are removed via the slag outlet by the scraper.
