Non-metallic minerals, as the cornerstone materials for industrial production, have their powdered products widely used across dozens of sectors, including construction materials, chemical industry, rubber, coatings, and new energy. From limestone powder in cement production and talc powder in coating systems, to carbon black used for rubber reinforcement and kaolin employed in separators for new-energy batteries, high-quality non-metallic mineral powders directly determine the performance and quality of end products.

In the processing of non-metallic mineral powders, the intended application scenarios directly determine the requirements for processing accuracy and purity. For example, heavy calcium carbonate powder used in high-end coatings must achieve micron-level fineness and high whiteness. A minimum of 95% is required to ensure the coating’s opacity and leveling properties. For talc powder used in rubber products, excellent dispersibility is essential to achieve uniform blending with the rubber matrix, thereby enhancing the tensile strength and abrasion resistance of the finished product.

Compared to the impact grinding used in traditional ball mills, vertical grinding machines are better suited to the characteristics of brittle non-metallic minerals. The raw ore is preprocessed by crushing equipment to... Small particles Then, it is fed into the grinding chamber by the feeding device, and... Stirring shaft With Grinding media The material is crushed under the high-pressure compression and shear forces. At the same time, hot air enters from the bottom of the grinding chamber, carrying the ground powder upward. —The不合格 coarse powder is returned to the grinding disc for re-grinding, while the合格 fine powder is carried by the airflow into the dust collection device for collection, ultimately yielding a finished powder with uniform particle size. This integrated process significantly shortens the processing flow and eliminates material loss and contamination during intermediate stages. To accommodate the specific characteristics of different non-metallic minerals, the equipment can flexibly adjust parameters such as grinding roller pressure, rotational speed, and hot-air temperature. For minerals with lower hardness, such as talc and gypsum, the grinding roller pressure can be reduced to enhance grinding efficiency; for minerals requiring high whiteness, such as kaolin and heavy calcium carbonate, the sealing structure can be optimized to minimize impurity contamination and ensure product purity.

More critically, non-metallic mineral powders processed by vertical grinding machines have achieved a qualitative leap in performance, further expanding the application boundaries and value potential of these materials. The particle size distribution of the processed mineral powders is uniform, effectively eliminating product defects caused by coarse particles—for instance, when used in coatings, it enhances the fineness and adhesion of the coating; when incorporated into plastic fillers, it ensures even dispersion of the mineral powder with plastic particles, thereby improving the rigidity and heat resistance of the final products. Meanwhile, the precise grinding process maximizes the preservation of the original characteristics of non-metallic minerals—such as the lubricity of talc, the adsorption capacity of kaolin, and the whiteness of heavy calcium carbonate—allowing these properties to fully exert their effects in end-use products. Take the new energy sector as an example: kaolin powder finely processed by vertical grinding machines boasts high purity and uniform particle size, making it an ideal coating material for lithium-ion battery separators. It enhances the separator’s high-temperature resistance and puncture strength, thereby ensuring the safety performance of the battery. In the construction materials sector, ultrafine limestone powder added to cement can optimize the hydration reaction of cement, boosting the strength and durability of concrete while reducing the amount of cement required, thus promoting resource recycling.
