Based on nearly 20 years mill research and operation experience, LUM Ultrafine Vertical Mill has been developed as the equipment for ultrafine powder grinding and separation. Its production introduces talents in ultrafine powder production and machine manufacturing industry, and absorbs the technologies and experience of ultrafine vertical mills from Germany, Japan and Taiwan, etc.
CLUM Ultrafine Vertical Mill is the specialized ultrafine grinding equipment for non-metallic ores. It suits for grinding non-flammable, non-explosive brittle materials with Moh’s hardness below 6 such as limestone, calcite, marble, talc, barite, brucite, wollastonite, pyrophyllite, dolomite, kaolin, lime, saponite, etc.
The mill takes Automatic Central Control System, widely used in paper-making, plastic, rubber, artificial stone, painting and coating industries. It is the specialized equipment for producing filler of large-scale paper-making plants and calcium carbonate for coating, and processing other large-scale ultrafine powder.
Advanced Technology, Reliable Equipment
A. Special grinding curves of grinding roller and grinding disc ensure stable and efficient operation of host machine.
B. Grinding roller takes mechanical position limiter, directly avoiding touching grinding disc. Therefore, destructive collision and violent shocks are avoided.
C. Special sealing design prevents dust from entering the inside of bearing to keep long-term operation of grinding roller.
D. The high-efficiency powder concentrator can freely adjust the particle sizes and ensure the accurate cutting point and reproducibility of products.
A. Fineness of finished products can be adjusted flexibly. Primary powder production can reach D97=10μm-20μm while the next powder separation attains D97=4-5μm easily. Finished products have advantages of high content of fine powder, high whiteness and more compact granularity.
B. Lingering time of materials in grinding cavity is short. The components and fineness of finished products can be measured and collected quickly, keeping stable quality of finished products.
Better Finished Products, Higher Profits
Smooth Operation, Lower Costs
A. Grinding roller grinds the materials directly. Its energy consumption is 10% lower than other types roller mill and 25-60% lower than that of ball mill.
B. No direct touch between grinding roller and disc and the special wearable alloy materials used in grinding roller shell and lining plates grant a long life expectancy of mill and save the costs on quick-wear parts.
C. Automatic control systems like PLC, DCS and Central Control System can be used to operate machines remotely, saving labor force.
A. Because of no touch between grinding roller and disc, there is no clang and slight vibration. The noise is 20-25 decibel lower than that of ball mill.
B. The whole set of system is fully sealed and operates with negative pressure. Besides, it is equipped with pulse dust collector so the exhaust emission completely meets related national standards.
Eco-friendly Design, Higher Standards
The output is 30% higher than that of traditional vertical mills.
The fineness is higher than that of peers, the 2μ powder is 7%-8% higher.
Power consumption is 10% lower than that of peers.
Product stability is far higher than that of peers; customers' viscosity is higher.
Operating rate is up to 95%-99%, which is considerably higher than that of peers.
