Dolomite is a key non-metallic mineral in the metallurgy, building materials, refractory materials, and glass and ceramics industries. The quality of the ground powder directly impacts the performance of steelmaking fluxes, refractory materials, and glass raw materials. As industry demands for purity, fineness, and whiteness increase, traditional grinding equipment struggles to meet the needs for large-scale and high-precision processing.
Shanghai Shibang has dedicated decades to the R&D of grinding equipment. Tailored to the characteristics of dolomite, the company offers complete equipment sets including the MTW European mill, LM vertical mill, MTW6X intelligent European mill, and PMD permanent magnet direct-drive mill, providing global customers with stable, energy-efficient, and environmentally friendly comprehensive dolomite grinding solutions. The standard dolomite grinding process comprises six major stages: crushing, drying, grinding, classification, powder collection, and dust removal. After crushing, the raw material enters the main grinding unit. The Shanghai Shibang LM Vertical Mill integrates crushing, drying, grinding, classification, and conveying into a single unit.
With an hourly output of 10–340 tons and adjustable finished product fineness of 80–400 mesh, it is suitable for large-scale production lines. Its comprehensive energy consumption is 30%–50% lower than that of ball mills, it occupies half the floor space, and it can be installed outdoors, significantly reducing infrastructure investment. For small and medium-sized projects, the MTW European mill is the preferred choice. Its curved scrapers increase the grinding surface area, while the drag-free spiral housing reduces energy consumption. Thin-oil lubrication extends bearing life, and the high-efficiency cage-type classifier prevents coarse particles from escaping, ensuring the finished product consistently meets specifications and meets the requirements for refractory materials and building material fillers.
For high-end refractory materials and glass raw materials, the LUM ultra-fine vertical mill or SCM ultra-fine pulverizer can be selected to produce high-purity dolomite micro-powder ranging from 325 to 2500 mesh. This powder features high whiteness, low iron content, and uniform particle size, meeting the requirements of high-end products. Shanghai Shibang equipment operates under fully sealed negative pressure and is equipped with high-efficiency pulse dust collectors, achieving dust emissions of <10 mg/Nm³. It features low noise levels and zero leakage, complying with environmental protection and safety standards. In terms of equipment configuration, the LM series vertical mills are selected for large-scale production lines to ensure stable, high output; the MTW series is chosen for small and medium-sized lines for outstanding cost-effectiveness; and the LUM/SCM series is selected for ultra-fine powder requirements. Shanghai Shibang offers EPC turnkey services, providing one-stop delivery from design and equipment manufacturing to installation, commissioning, and operational training. Wear-resistant parts are made of high-chromium alloy, ensuring long service life and low maintenance costs. Our equipment has been operating stably in dozens of dolomite production lines both domestically and internationally.
Whether for new production lines or equipment upgrades, Shanghai Shibang can customize solutions based on production capacity, fineness requirements, and ore quality.
