Abstract：In this paper, combined with the characteristics of the application of ground calcium carbonate(GCC) powder material,the innovation points and the research direction of the development of HRM ultra-fine vertical mill were explored. By the GCC, talc and other non-metallic mineral powder superfine processing engineering application experience, the focus of research in HRM vertical superfine grinding device for grinding structure, disc rotating speed, grinding pressure roller and grading device for dynamic and static grading wheel structure, material selection and speed for the design and fabrication. The practice prove that HRM vertical superfine grinding the production of superfine product 2 μm fine powder volume content ≥22%,d₁₀₀≤45 μm, d₅₀≤6.5 μm, tons of product power consumption is less than or equal to 55.6kWh/t, specific surface area reach 0.83-0.92 m²/g, equipment running efficiency reach 98%.
