Deep processing technology of Non-metallic Ores is key to increasing their added value, with ultra-fine grinding technology being particularly important.
This process not only requires the minerals to be ground to the micron level but also ensures the uniformity of particles, sphericity, and consistency of chemical composition.
For example, kaolin and heavy calcium carbonate used in paper-making require a product fineness of over 90% at -2μm, with a whiteness of over 90%. For high-grade coating fillers, the fineness of heavy calcium carbonate powder needs to reach 1250 mesh.-In addition, as a ceramic opacifier, zirconium silicate requires an average fineness between 0.5~1μm, while for fillers, the fineness of wollastonite needs to be less than 10μm.
In terms of purity, non-metallic mineral products must maintain their original composition during the grinding process to avoid contamination. For white minerals, such as calcined kaolin and talc powder, the whiteness needs to reach over 90%. The shape of the powder is also an important quality indicator. For example, when wollastonite is used as a reinforcing body in composite materials, it is necessary to maintain its needle-like crystalline state, with an aspect ratio greater than 8~10.
At present, physical grinding is the main method for preparing ultra-fine powder materials, which is widely used due to its low cost, simple process, and large output. Commonly used ultra-fine grinding equipment includes HGM Series Micro Powder Mill, CLUM Series Ultra-fine Vertical Roller Mill, and Enhanced Roller Grinding Mill, which can meet the deep processing needs of different non-metallic mineral products.
