As the main building decoration material, about 70% of the marble resources are converted into waste during mining, cutting and polishing,  causing serious waste of resources and environmental pollution. The issue of comprehensive utilization of marble tailing and waste residue are is imminent. Marble tailing is non-metallic mineral, its main component is calcium carbonate. At present, the

Heavy calcium carbonate dry production process and equipment Heavy calcium carbonate is made from natural minerals such as calcite, marble, limestone, chalk, etc., and is processed into powder products that meet the fineness requirements of the application field. Among them, the dry process is generally used to produce heavy calcium carbonate products with d97≥3-5μm. The

Why is Calcium Carbonate Indispensable in the Shoe Material Industry?       Which Shoe Materials Need Calcium Carbonate Powder? The main resins used in the shoe material industry include PVC (polyvinyl chloride), RB (rubber), PU (polyurethane), TPR (thermoplastic rubber), and others. Adding calcium carbonate powder primarily reduces costs and increases the wear resistance of

Application fields of green silicon carbide The application fields of green silicon carbide are quite extensive, which are specifically manifested in the following aspects:     Electronic industry In this field, green silicon carbide is mainly used to manufacture high-performance semiconductor devices and optoelectronic devices. Its radiation resistance and stability are better than traditional silicon

Some Tips on Pressure in Pneumatic Conveying Pneumatic conveying is a method of using compressed air to transport powdered or fine granular materials to a designated location. In the process of pneumatic conveying, conveying pressure is a key parameter that directly affects efficiency and reliability.   This article will explore in depth the requirements, losses,

Key Considerations When Using Talc in Modified Plastics Talc, a hydrated magnesium silicate, belongs to the “phyllosilicate” class with a trihedral three-layer structure. Its structure comprises a brucite layer (magnesium hydroxide, MgO·H2O) sandwiched between two silicon dioxide (SiO2) layers. These layers are held together by weak van der Waals bonds, making them prone to sliding

The Cost-Effective Calcium Carbonate in Body Pigments In recent years, advancements in mineral processing have led to a greater focus on the functionality of mineral fillers. People are now interested in properties like increasing hardness, improving hiding power, and enhancing resistance to corrosion and heat. Consequently, the use of non-metallic mineral fillers in coatings has

From Ore to Powder: Kaolin Purification, Crushing, Modification Kaolin is a crucial non-renewable mineral resource with few high-quality deposits. At present, more industries demand more high-end kaolin. The market demand has outpaced overall growth, worsening supply-demand imbalances in China. Therefore, studying and applying various processing technologies is essential to make this mineral material suitable for
