High-end plastics, water-based coatings, and paper fillers impose stringent requirements on the fineness of calcium carbonate powder. Conventional 325-mesh coarse powder offers limited added value, while market demand for 600–2500-mesh ultrafine calcium carbonate powder continues to rise. Conventional Raymond mills struggle to consistently produce ultrafine powder finer than 2000 mesh, while air-jet mills consume excessive energy and have low output. The SBM LUM Ultrafine Vertical Mill perfectly balances production capacity, fineness, and operating costs.
The LUM ultra-fine vertical mill integrates Taiwanese roller crushing technology with German high-precision classification technology. Featuring an integrated design for ultra-fine grinding, classification, and collection, it allows for flexible adjustment of the finished product’s fineness within the 325–2,500 mesh range. The D97 particle size is controllable, the particle size distribution is narrow, and the product exhibits high whiteness and purity. It effectively controls iron impurities, fully meeting high-end filler production standards.
Its core energy-saving advantages are outstanding, achieving comprehensive electricity savings of 30%–50% compared to traditional ultra-fine powder equipment, resulting in significant cost advantages in electricity bills for long-term, large-scale production. The equipment features a hydraulic tilting maintenance structure, eliminating the need for large lifting equipment when replacing wear parts such as grinding rollers and liners. This reduces maintenance time by 60% and minimizes downtime-related losses. The entire unit operates in a sealed, negative-pressure environment and is equipped with a pulse dust collection system, ensuring dust-free production that meets the environmental standards of chemical and new materials enterprises.
The equipment lineup includes three main models—LUM15-3X, LUM16-3X, and LUM17-3X—with hourly capacities ranging from 1.5 to 16 metric tons. It is suitable for small and medium-sized ultra-fine calcium carbonate processing plants and can also be configured in parallel to form production lines with annual capacities of 100,000 to 300,000 metric tons of ultra-fine powder. In addition to calcium carbonate, the equipment can also process ultrafine non-metallic minerals such as graphite, talc, mica, and bentonite.
Many customers are unclear about which equipment model corresponds to their target mesh size. There is a significant difference in production capacity and energy consumption between 2000-mesh ultrafine powder and 600-mesh fine powder; blind purchasing can easily double production costs. If you plan to launch an ultrafine calcium carbonate production line, please leave a message on Business Pass specifying your raw materials, target mesh size, and hourly production capacity. Shibang engineers will provide a complete solution including fineness testing, equipment selection, and supporting dust collection and classification systems, along with a free calculation of the processing cost per metric ton.
