Calcium carbonate powder is widely used in plastics, rubber, coatings, paper, and construction materials. It is mainly produced by grinding natural minerals such as limestone, marble, and calcite. In a complete calcium carbonate production line, key equipment includes crushers, conveyors, storage bins, grinding mills, classifiers, dust collectors, and packaging systems — among which, the grinding […]

Calcium carbonate (CaCO₃) is one of the most widely used non-metallic mineral raw materials in industrial applications. It plays an essential role in plastics, papermaking, coatings, rubber, ink, and pharmaceuticals. As downstream industries demand increasingly higher material performance, ultrafine grinding technology has become the key to enhancing the added value of calcium carbonate. A calcium

Calcium carbonate (CaCO₃) is a widely used inorganic non-metallic material, extensively applied in plastics, paper, coatings, rubber, and many other industries. Its performance—particularly in terms of particle size and morphology—depends almost entirely on one crucial stage: grinding. This Q&A aims to explore the necessity, key equipment, and technologies involved in calcium carbonate grinding. Q1: Why

The key technical specifications of ultrafine calcium carbonate—particle size, specific surface area, crystal form, and oil absorption—directly impact its application performance. While other indicators are important, they are relatively easy to achieve industrially. For specialized products, different applications place varying emphasis on various indicators and require different requirements. Particle Size and Specific Surface Area The

Driven by global energy transition and “dual-carbon” strategies, lithium-ion batteries are core components of electric vehicles and energy storage systems. Their performance improvement and cost reduction are key industry priorities. Negative electrode materials, the “energy heart” of lithium batteries, determine capacity, cycle life, and safety. Traditional graphite anodes, nearing their 372 mAh/g capacity limit, cannot
