LUM Ultrafine Vertical Roller Mill for Stone Powder Production
Revolutionizing Stone Powder Production with Vertical Grinding Technology
In today’s competitive industrial landscape, the demand for high-quality stone powder continues to grow across various sectors including construction, chemicals, and manufacturing. The LUM Ultrafine Vertical Roller Mill represents a significant leap forward in grinding technology, offering unprecedented efficiency and precision in stone powder production.
Advanced Engineering for Superior Performance
What sets the LUM Ultrafine Vertical Roller Mill apart is its integration of cutting-edge technologies from different regions. The mill incorporates the latest Taiwan grinding roller technology combined with German powder separating technology, creating a machine that delivers exceptional performance in ultrafine powder grinding, grading, and transporting. This international collaboration in design ensures optimal results for various stone materials including limestone, calcite, dolomite, and barite.
The LUM mill operates with an input size of 0-10 mm and achieves a production capacity of 5-18 tph, making it suitable for medium to large-scale operations. Its compact design and efficient operation make it an ideal choice for facilities with space constraints while maintaining high output requirements.
Key Technological Innovations
One of the most remarkable features of the LUM Ultrafine Vertical Roller Mill is its unique roller shell and lining plate grinding curve design. This innovation addresses common problems in traditional grinding mills such as materials’ long lingering time, repeated grinding, and high iron content. The specially designed curves make it easier to generate material layers and achieve high rates of finished products through single-pass powder milling.
The mill’s double position-limiting technology represents another breakthrough. By employing both electronic limiting technology and mechanical limiting protection technology, the system prevents destructive impacts that could occur during machine vibration, ensuring operational stability even under challenging conditions.
Energy Efficiency and Environmental Considerations
Modern manufacturing demands not only high performance but also environmental responsibility. The LUM Ultrafine Vertical Roller Mill addresses both concerns through its PLC control system and multi-head powder separating technology. This combination completely solves the dual challenges of high-precision powder diameter control and fast switching between different production demands. Users can accurately control grinding pressure, revolving speed, and other critical parameters, resulting in energy consumption reductions of 30%-50% compared to conventional grinding mills.
For operations requiring different specifications, we also recommend considering our MW Ultrafine Grinding Mill, which handles input sizes of 0-20 mm with a capacity range of 0.5-25 tph. This machine is particularly suitable for customers who need to make ultra-fine powder while maintaining environmental compliance through its efficient pulse dust collector and muffler system.
Maintenance and Operational Efficiency
The LUM mill’s reversible structure demonstrates thoughtful design consideration for maintenance needs. Recognizing the challenges posed by heavy grinding rollers, our engineers developed a system that allows operators to easily and rapidly move grinding rollers out of the body for inspection and replacement of roller shells and liner plates. This design significantly reduces downtime and associated losses.
Both the LUM Ultrafine Vertical Roller Mill and MW Ultrafine Grinding Mill benefit from our company’s digitalized processing capabilities. With tens of lines of numerical controlling machine tools, operations including steel plate cutting, bending, planing, milling, and paint spraying are all controlled numerically, ensuring high machining precision, particularly for core components.
Applications Across Industries
The versatility of the LUM Ultrafine Vertical Roller Mill makes it suitable for numerous applications beyond traditional stone processing. It efficiently handles materials such as petroleum coal, gypsum, marble, talc, and coal powder, producing superfine dry powder of non-metal ores. The resulting powders find applications in chemicals, paints, cosmetics, pharmaceuticals, and food additives, demonstrating the machine’s broad utility across multiple sectors.
