Summary :This article introduces dolomite grinding processes and applications, recommending equipment such as the SBM LM Vertical Mill and MTW European Mill, which cover a range of production capacity and fineness requirements. The equipment is energy-efficient and environmentally friendly, and comes with comprehensive end-to-end services.
Dolomite is a widely used non-metallic mineral primarily composed of magnesium calcium carbonate. Due to its high whiteness and strong chemical stability, it is extensively utilized in refractory materials, glass manufacturing, architectural coatings, plastic fillers, and environmental desulfurization. The particle size, purity, and whiteness of the powder directly determine the quality of downstream products; therefore, a mature grinding process and reliable equipment are essential for dolomite deep processing enterprises to improve quality and enhance efficiency. SBM has dedicated decades to the R&D of grinding equipment. Targeting the material properties of dolomite—which has a Mohs hardness of 3.4–4.0—the company has developed a full range of specialized grinding equipment to meet processing needs ranging from conventional fine powders to high-end ultrafine powders.
A standard dolomite grinding production line consists of six major processes: raw material crushing, pre-treatment, grinding, classification, powder collection, and dust removal. After being processed by a jaw crusher, the raw ore is conveyed to the main grinding unit. For large-scale production projects, the SBM LM Series Vertical Mill is the equipment of choice. This integrated unit combines drying, grinding, classification, and conveying functions. It offers strong adaptability to feed particle sizes, with finished product fineness freely adjustable between 80 and 400 mesh, and a maximum hourly output of up to 340 tons. Its integrated structure reduces the equipment’s footprint to just half that of traditional ball mills and allows for open-air installation, significantly lowering infrastructure costs. With a 30%–50% reduction in overall energy consumption compared to conventional mills, it is ideally suited for raw material preparation in the refractory industry and large-scale glass manufacturing.
Small and medium-sized processing plants and building material filler production lines can opt for the MTW Series European mill. The equipment features innovative curved blades and a drag-free spiral housing, providing a larger grinding surface and lower air resistance. Combined with a thin-oil lubrication system, it ensures smooth transmission and extends bearing service life. The built-in high-efficiency cage classifier effectively prevents coarse powder leakage, ensuring uniform particle size. With a production capacity range of 3–45 tons per hour, it perfectly meets the needs of small and medium-sized operations. For enterprises requiring the production of high-end dolomite ultrafine powder (800–2500 mesh) for use in high-end coatings and functional plastics, the LUM ultrafine vertical mill or SCM ultrafine micro-powder mill are recommended. Both models strictly control iron content, ensuring high whiteness of the powder and meeting high-end industrial material standards.
Additionally, the new-generation MTW6X Smart European Mill and PMD Permanent Magnet Direct-Drive Mill are equipped with an IoT remote control system. They feature further improved power transmission efficiency and significant energy savings, making them ideal for upgrading and retrofitting older production lines. The entire production line adopts a negative-pressure sealed design, paired with a pulse dust collector, ensuring dust emissions meet standards, low operational noise, and compliance with local environmental regulations.
