    ACTIVE LIME PRODUCTION LINE

    Active lime is made from minerals with high calcium carbonate content, such as limestone, dolomite, and chalk, which are calcined at 1000-1100°C. The choice of active lime production process is determined by many factors: investment cost, lime activity requirements, fuel selection, raw material size, system capacity requirements, and environmental protection requirements. We will determine the production process according to the customer's specific conditions and requirements.

    Advantages of Specialized Equipment for Producing Magnesium Oxide from Magnesium Hydroxide

    Henan Zhengzhou Mining Machinery Co.,Ltd., has long specialized in the calcination of magnesium hydroxide into magnesium oxide. By developing dedicated rotary kilns and complete production lines—leveraging five key equipment advantages—the company resolves traditional production pain points.

    Industrial Rotary Kilns for Calcination | ZK MACHINE

    As the core primary equipment for continuous high-temperature calcination, the rotary kiln's operational stability, temperature control accuracy, sealing performance, and energy-saving efficiency directly determine the production capacity ceiling and economic benefits of the entire production line.

    High-efficiency and energy-saving vertical cooling machine: A solution for cooling materials in multiple industries

    The vertical cooling machine adopts a vertical cylindrical structure. Through the reverse heat exchange between cold air and high-temperature materials, it achieves rapid cooling. Its multi-chamber discharge design, combined with the forced air supply system, enables the material temperature to drop rapidly from 300-400℃ to 100-200℃. The hot air is then recycled as secondary energy, significantly improving the overall thermal efficiency. The equipment has few wear parts and no exhaust emissions, which better aligns with the green production concept, reducing the operating costs of the enterprise by over 30%.
