LUM Ultrafine Vertical Roller Mill: The Pinnacle of Stone Powder Production
In the demanding world of industrial mineral processing, achieving consistent, high-quality ultra-fine powder is a critical challenge. Traditional grinding methods often fall short, plagued by inefficiency, high energy consumption, and inconsistent particle size distribution. The industry demands a solution that combines precision, reliability, and environmental responsibility. Enter the LUM Ultrafine Vertical Roller Mill, a technological masterpiece engineered to redefine the standards of stone powder production.
Engineered for Excellence: Core Design Philosophy
The LUM Ultrafine Vertical Roller Mill is not merely an iteration of previous designs; it represents a fundamental leap forward. Independently developed by LIMING Heavy Industry, it synthesizes cutting-edge global technologies—most notably advanced Taiwanese grinding roller engineering and German precision powder separation systems. This integration creates a seamless process where grinding, classification, and transportation are unified into a single, highly efficient system. With an input size of 0-10 mm and a capacity range of 5-18 tph, it is perfectly calibrated for high-volume, precision ultrafine powder production.
The mill’s defining feature is its unique grinding curve, meticulously designed for the roller shell and lining plate. This innovation directly addresses the chronic issues of traditional mills: material over-grinding, long retention times, and iron contamination. By promoting the stable formation of a material bed and enabling efficient single-pass milling, the LUM mill dramatically increases yield while simultaneously enhancing the whiteness and purity of the final product. This results in a superior powder ideal for high-value applications in paints, coatings, plastics, and advanced ceramics.
Unmatched Operational Advantages
Operational stability and ease of maintenance are where the LUM mill truly distinguishes itself. Its revolutionary double position-limiting technology employs both electronic sensors and mechanical stops to prevent destructive contact between the grinding roller and millstone, even under severe vibration. This safeguard is crucial for continuous 24/7 operation, ensuring longevity and protecting your capital investment.
Furthermore, LIMING’s engineers have masterfully solved the maintenance dilemma posed by heavy grinding components. The mill’s reversible structure, coupled with a hydraulic adjustment system, allows operators to swiftly and safely swing the grinding roller out of the main body. This design facilitates rapid inspection, replacement of wear parts like roller shells and liner plates, and significantly reduces costly downtime—a feature maintenance teams deeply appreciate.
Precision, Efficiency, and Environmental Stewardship
At the heart of the powder quality control is the multi-head powder separating technology managed by an advanced PLC control system. This setup solves the twin challenges of achieving high-precision particle size cuts and quickly switching between different product specifications. Users gain exact control over grinding pressure and rotational speed, allowing fineness adjustment within a remarkably broad spectrum. Compared to conventional mills, this intelligent system reduces energy consumption by an impressive 30-50%, delivering substantial operational cost savings.
Environmental compliance is integral to the design. The entire milling system operates under negative pressure, and is equipped with high-efficiency pulse dust collectors and silencers. This ensures a dust-free workshop and noise levels well within international standards, making the LUM mill a responsible choice for modern, eco-conscious production facilities.
The LIMING Ecosystem: Beyond a Single Machine
While the LUM Ultrafine Vertical Roller Mill stands as a flagship for ultra-fine processing, LIMING’s commitment to providing tailored solutions is reflected in its comprehensive product portfolio. For projects requiring different throughputs or dealing with slightly coarser requirements, the MW Ultrafine Grinding Mill presents an excellent alternative. Designed for making ultra-fine powder from materials like limestone, calcite, and dolomite, the MW series boasts a capacity of 0.5-25 tph and an adjustable fineness between 325-2500 meshes. Its standout feature is a grinding chamber free of rolling bearings and screws, eliminating common failure points and enabling worry-free, continuous operation. Like all LIMING equipment, it is built with digital precision and backed by a guaranteed supply of original spare parts.
Choosing LIMING means investing in more than just machinery; it’s a partnership for sustainable productivity. From the digitally machined core components to the comprehensive after-sales support and readily available spare parts, every aspect is designed for worry-free operation. For producers aiming to lead in the competitive arena of stone powder, the LUM Ultrafine Vertical Roller Mill is the definitive tool to achieve unparalleled quality, efficiency, and reliability.
Frequently Asked Questions (FAQs)
1. What is the primary advantage of the LUM Ultrafine Vertical Roller Mill over a traditional ball mill?
The LUM mill offers significantly higher grinding efficiency and lower energy consumption—typically 30-50% less power usage. It also produces powder with higher whiteness and lower iron contamination due to shorter material retention time and no direct metal-to-metal contact in the grinding zone. Its integrated drying, grinding, and classifying system also saves considerable floor space.
2. How is the fineness of the final powder controlled and adjusted?
Fineness is precisely controlled via the advanced multi-head cage-type powder separator with PLC automation. Operators can adjust the rotational speed of the separator’s rotor to accurately cut the particle size. Additionally, the grinding pressure can be modulated through the hydraulic system, allowing for flexible production of powders with different specifications from 325 to over 2500 meshes.
3. What materials is the LUM mill best suited for?
It is ideally suited for grinding non-metallic, non-flammable minerals with Mohs hardness below 7 and moisture content below 10%. This includes limestone, calcite, dolomite, talc, barite, marble, gypsum, and petroleum coke, producing superfine powder for high-end industrial applications.
4. How does the maintenance-friendly design of the LUM mill reduce downtime?
The mill features a reversible housing and a hydraulic system that allows the heavy grinding roller to be easily turned out of the mill body. This provides direct and ample access for inspection, replacement of wear parts (roller shell, lining plate), and other maintenance tasks without complex disassembly, drastically shortening maintenance windows.
5. What environmental features are incorporated into the system?
The entire system operates under negative pressure, preventing dust spillage. It is equipped with a high-efficiency pulse-jet bag filter that ensures dust emissions are far below national standards. Noise is minimized through integrated silencers and the stable, low-vibration operation of the mill itself.
6. Does LIMING provide support for spare parts and technical service?
Yes, absolutely. As a manufacturer covering both production and sales, LIMING takes full responsibility for every machine. We guarantee a sufficient supply of original, high-quality spare parts and offer comprehensive technical services to ensure continuous, worry-free operation of your grinding mill throughout its lifecycle.
