LUM Ultrafine Grinding Mill
Input Size: 0-10mm
Capacity: 3-18T/H
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.
LUM Ultrafine Vertical Grinding Mill can effectively control the product size, chemical composition and iron content, and ensure the purity and whiteness of finished materials.
LUM Grinding Mill can accurately control grinding pressure, speed and other parameters. Compared with ordinary mills, the energy consumption is reduced by 30%-50%.
LUM Ultrafine Vertical Grinding Mill adopts reversible structure. With the hydraulic adjustment system, vulnerable parts can be easily and quickly repaired and replaced.
LUM Ultrafine Vertical Grinding Mill is sealed and operates under negative pressure, characterized by no dust spillover, small vibration of equipment, low noise, and more environmentally friendly production.
We offer customized EPC turnkey grinding engineering services, providing end-to-end guidance—from initial project initiation and process design to final commissioning—supported by a professional design institute team, thereby meeting the construction requirements for integrated sand and powder production lines.
Prioritize the investigation of the following three core causes: first, a wide variation in feed particle size combined with the presence of metallic foreign particles, which leads to instability of the material bed; second, a mismatch between the hydraulic loading pressure and the hardness of the material; third, an imbalance in the system's air flow rate, resulting in an excessively thin or thick material bed; these issues can be rapidly mitigated by adjusting the feeding rate, pressure, and air flow parameters accordingly.
Utilizing the material-bed extrusion crushing principle, this system achieves a grinding efficiency 1.65 times that of a ball mill, reduces power consumption by approximately 30%, and features high equipment integration—eliminating the need for multiple auxiliary units—thereby significantly lowering overall operational energy consumption.
It is widely used in applications such as the preparation of specialized aggregates for dry-mixed mortar, large-scale production of high-quality sand and gravel, pre-milling of ores in metallurgy and mining operations, preparation of pulverized coal for blast furnace injection, and resource recovery from industrial waste residues, spanning multiple industries including building materials, metallurgy, and chemical engineering.
The main motor drives the grinding disc to rotate, causing the material to enter the grinding roller compression zone under the action of centrifugal force. The material undergoes grinding via inter-particle crushing within the material bed; the crushed material is then graded by external classification equipment, with oversized particles recirculated for further grinding, ultimately yielding qualified sand powder.
It is suitable for processing brittle materials with a Mohs hardness below 7, compressive strength below 260 MPa, and non-flammable, non-explosive, and non-corrosive properties; it covers dozens of common ores, including limestone, quartz, granite, coal gangue, dolomite, and others.
