Gypsum (natural gypsum, desulfurized gypsum) is a key raw material in the building materials, cement retarder, chemical, and agricultural sectors. The quality of gypsum powder directly affects the quality of gypsum board, putty, cement, and soil conditioners. With the development of the building materials and environmental protection industries, large-scale, energy-efficient, and intelligent gypsum powder production has become a trend.
Addressing gypsum’s characteristics of easy grindability and heat sensitivity, Shanghai Shibang has introduced specialized equipment—the LM Vertical Mill, MTW European Mill, and LUM Ultrafine Mill—to provide comprehensive powder processing solutions from raw material to finished product, suitable for various gypsum processing projects. Key control factors in gypsum grinding include fineness, moisture content, and temperature, with overheating strictly avoided to prevent quality degradation.
The Shanghai Shibang LM Vertical Mill integrates drying, grinding, classification, and conveying into a single unit. It can process desulfurized gypsum with high moisture content, completing both drying and grinding in a single pass. The finished product fineness is adjustable from 80 to 400 mesh, with an hourly output of 10–340 tons. The system operates under negative pressure with zero dust leakage, low noise, and meets environmental standards, making it the preferred equipment for large-scale gypsum powder production lines.
For small and medium-sized production lines, the MTW European mill is recommended. It features a compact design, simple operation, and smooth running. Its efficient classification system ensures uniform fineness, meeting the standard requirements for construction gypsum and cement retarders. It offers low investment costs and quick returns.
For producing ultra-fine gypsum powder for high-end medical and ceramic mold applications, the LUM ultra-fine vertical mill is recommended. It produces finished products ranging from 325 to 2500 mesh, featuring a concentrated particle size distribution, excellent flowability, and high purity, meeting the demands of high-end products. The equipment is easy to maintain, operates stably, and has low long-term operating costs.
Shanghai Shibang’s gypsum grinding production lines offer flexible configurations: large-scale building materials and cement enterprises use the LM vertical mill, which delivers stable, high output and a high degree of automation; small and medium-sized processing plants use the MTW European mill, which offers outstanding value for money; and the LUM ultra-fine mill is used for ultra-fine, high-end powder. The equipment employs an intelligent control system that precisely regulates temperature, airflow, and fineness to ensure consistent gypsum powder quality; wear-resistant components are tailored to the properties of gypsum, ensuring long service life, low failure rates, and hassle-free operation and maintenance.
Whether for natural gypsum powder production or the resource utilization of industrial by-product desulfurization gypsum, Shibang offers customized EPC turnkey services to help enterprises achieve compliant production, reduce costs, and improve efficiency. These solutions have been successfully applied in numerous gypsum projects both domestically and internationally.
