Cronus ultrafine grinding mill machine is applied in the calcium carbonate powder market of Nanyang

Nanyang City, Henan Province, stands as a pivotal hub for calcium carbonate (CaCO3) production in central China, with a robust industrial ecosystem supported by abundant mineral resources and strategic investments. Here’s a comprehensive analysis tailored to your requirements:

 Calcium Carbonate Mines & Resources in Nanyang

Nanyang, particularly Nanzhao County, is renowned as the “Calcium Capital of China”  The Key highlights include:

• Reserves: Total CaCO3 reserves exceed 1 billion tons, with 800 million tons recoverable. Notably, Nanzhao holds 50 million tons of high-purity calcite suitable for food-grade applications.
• Geographic Concentration: Mines cluster in Nanzhao’s Nanhegou Town and Changling Industrial Park, where upstream mining enterprises supply raw materials to 242 midstream powder processors.
• Emerging Areas: Xixia County, through a partnership with global giant Omya, is developing a 3 million tons/year CaCO3 base leveraging its high-white (≥92%) and high-purity deposits .

This client is a major calcium carbonate powder producer in the Nanyang area. Currently, it mainly produces high fineness, high whiteness and high purity premium calcium carbonate micropowder. The main machines it uses are ultrafine ring roller mill and ultrafine vertical mill. The third-phase project is currently in preparation. After completion, it is expected that the total equipment production capacity will reach 300,000 tons per year.

Production Capacity of Nanyang: Midstream enterprises produce 650,000 tons/year of CaCO3 powders, with ultra-fine grades (800–3,000 mesh) accounting for 30% of output.

Applications & Market Dynamics

CaCO3 from Nanyang serves 9 major industries, with coatings and plastics as primary drivers:

• Coatings (40% of demand): Global players like Nippon Paint and Skshu Paint operate production bases in Nanzhao, using 1,250–3,000 mesh CaCO3 for waterborne paints and architectural coatings.
• Plastics (30%): CaCO3 fillers enhance rigidity in PVC pipes (produced by Yushu Pipe Industry) and automotive composites, with 600–1,250 mesh grades dominating this segment.
• Emerging Sectors:
  • New Energy: CaCO3 is used in battery separators and photovoltaic encapsulants, aligning with China’s green energy goals.
  • Food & Pharmaceuticals: Nanzhao’s calcite reserves support GMP-certified production for dietary supplements and antacids.

Nanyang’s CaCO3 industry is positioned for sustained expansion, driven by:

• Policy Support: The Nanyang CaCO3 Industrial Chain Plan aims to achieve ¥10 billion annual output by 2030 through investments in R&D and green technologies.
• Environmental Integration:
  • Circular Economy: Nanzhao’s Resource Recycling Industrial Park recycles 95% of mining waste into aggregates and construction materials.
  • Emission Standards: Stringent regulations (e.g., PM ≤10mg/m³) push adoption of baghouse filters and closed-loop systems.
• Technological Upgrades:
  • Smart Manufacturing: Xintai Calcium’s provincial-level intelligent workshop reduces energy consumption by 20%.
  • Functional Products: R&D focuses on nano-CaCO3 for self-healing coatings and biodegradable plastics, targeting premium markets.
• Export Potential: With proximity to the China-Europe Railway, Nanyang is eyeing exports to Southeast Asia and Europe, particularly for ultra-fine and activated grades.

• Resource Depletion: High-grade reserves may decline by 2035, necessitating investments in low-grade ore beneficiation.
• Competition: Southern China’s Guangxi Province dominates precipitated CaCO3, but Nanyang’s natural whiteness (≥92%) and cost efficiency (¥800–1,200/ton) remain competitive.
• Talent Shortage: Collaboration with Zhengzhou University and vocational schools is fostering expertise in mineral engineering and nanomaterials.
