Abstract: The LUM Ultrafine Vertical Mill specializes in high-end ultrafine powders, offering stepless adjustment from 325 to 2500 mesh. Specialized wear-resistant components reduce iron impurities, making it suitable for the fine processing of drilling-grade barite, paper-grade calcium carbonate, and petroleum coke for carbon products.
Oil and gas drilling weighting agents, heavy calcium carbonate for paper coating, and petroleum coke carbon raw materials for electrolytic aluminum impose stringent requirements on powder fineness, purity, and particle size distribution. Conventional mills used to process ultrafine powders often suffer from excessive iron content, a mixture of coarse and fine particles, and extremely high energy consumption. SBM’s LUM Ultrafine Vertical Grinder integrates Taiwanese hydraulic roller grinding technology with a German dual-turbine classification system, making it a standardized piece of high-end equipment for ultrafine powders.
The LUM ultra-fine vertical mill produces finished products with a fineness range of 325–3,000 mesh, meeting market demand for ultra-fine powders in the 600–3,000 mesh range. The D97 particle size is precisely controllable, the proportion of fine particles under 2 μm is stable, and the particle size distribution is narrow, fully satisfying raw material standards for the coatings, plastics, oilfield, and carbon industries. The grinding components are made of non-magnetic, special wear-resistant alloys, ensuring no iron impurities are released during the grinding process. When processing barite and calcite, the equipment guarantees that the powder’s whiteness and specific gravity meet standards, while petroleum coke powder has an extremely low iron content that does not affect the electrical conductivity of anodes.
The equipment offers outstanding energy-saving advantages, reducing energy consumption by 30%–50% compared to traditional ultrafine mills. The hydraulic roller-tilting structure allows for the inspection and replacement of wear parts without disassembling the entire machine, reducing downtime for maintenance by 60%. The entire system operates in a fully enclosed, negative-pressure environment and is equipped with explosion-proof dust collection devices, eliminating safety hazards in the workshop when processing flammable powders such as petroleum coke. Single-unit production capacity ranges from 1.5 to 16 t/h, with multiple models available—including the LUM15-3X, LUM16-3X, and LUM17-3X—making it suitable for small and medium-sized ultrafine powder processing plants.
The workflow is straightforward: material is fed into the grinding disc via a feeder, where centrifugal force propels it toward the grinding rollers to form a material bed for pulverization. The airflow carries the powder into a high-precision classifier; coarse particles fall back for secondary grinding, while qualified ultrafine powder is collected in a pulse dust collector. Iron chunks within the ore fall by their own weight into the discharge port for automatic removal, preventing hard objects from wearing down the grinding rollers. Numerous domestic production lines for oilfield barite powder and high-end calcium carbonate fillers utilize LUM ultrafine vertical mills, with the finished products supplied directly to paint manufacturers and oil and gas extraction companies.
Investment in ultrafine powder processing equipment is strongly correlated with ore quality and target fineness; blindly selecting a model can easily result in excessively high power consumption per metric ton of powder and finished products that fail to meet downstream procurement standards. If you process ultrafine raw materials such as calcite, barite, or petroleum coke, please leave a message via the Business Messenger on this page specifying the ore’s whiteness, target mesh size, and daily production capacity.

FAQ
Q: What is the single-unit production capacity of the LUM ultrafine vertical mill for processing 3,000-mesh heavy calcium carbonate for paper coating?
A: The LUM17-3X has a production capacity of 2.3–3.8 t/h for 3,000-mesh heavy calcium carbonate, with high classification accuracy and the ability to achieve zero screen residue.
Q: Does grinding petroleum coke in the LUM ultrafine vertical mill increase the iron content of the powder?
A: The grinding rollers and grinding disc are made of non-magnetic, wear-resistant alloy, resulting in virtually no iron leaching, and meeting the purity standards for carbon raw materials used in electrolytic aluminum.
Q: What is the key difference between the LUM ultra-fine vertical mill and a standard vertical mill?
A: It is equipped with a dual-turbine high-precision classifier, achieving a fineness of 2,500–3,000 mesh, and features a hydraulically tilting maintenance structure, specifically designed for high-end ultra-fine powders.
