Liming Machinery Drives Gypsum Resource Utilization with Advanced Grinding and Calcination Technologies

At the 24th Global Gypsum Conference & Exhibition, Istanbul – Liming Machinery will demonstrates integrated processing solutions for natural gypsum and industrial by-product gypsum, addressing the industry's growing focus on sustainability and resource efficiency.

The global gypsum industry faces converging challenges: rising demand for construction materials, increasing volumes of industrial by-product gypsum requiring treatment, and intensifying pressure to reduce energy consumption and environmental impact. Liming Heavy Industry, exhibiting at the 24th Global Gypsum Conference in Istanbul, presents processing technologies designed to address these challenges through efficient grinding, precise calcination, and comprehensive system integration.

Technology Portfolio for Gypsum Processing

Liming Heavy Industry's gypsum processing equipment range encompasses primary grinding technologies suited to different production scales and material characteristics. The MTW European Trapezium Grinding Mill features advanced grinding technology with optimized transmission, lubrication, and air duct systems, delivering stable operation with reduced energy consumption for large-scale gypsum powder production. The LM Vertical Mill integrates crushing, drying, grinding, grading, and conveying functions in a single unit, offering high grinding efficiency and strong drying capability that supports increased single-unit output and large-scale production.

The company's calcination equipment includes fluidized bed furnaces and rotary kilns designed for precise temperature control and consistent product quality. For natural gypsum, the flue gas calcination process achieves simultaneous drying and calcination, optimizing material properties before milling. For high-moisture industrial by-product gypsum such as desulfurization gypsum, a separated pre-drying and calcination process prevents caking and blockage while enabling stable crystal form conversion.

Addressing Industrial By-Product Gypsum Challenges

Industrial by-product gypsum—including phosphogypsum, desulfurization gypsum, fluorogypsum, and titanium gypsum—represents both an environmental liability and a resource opportunity. With cumulative stockpiles exceeding 1.1 billion tons in China alone, effective utilization has become a priority for solid waste treatment and green low-carbon development.

Liming Machinery's integrated solutions for by-product gypsum processing encompass harmless pretreatment and high-value resource utilization. Processed materials can be applied across five major sectors: building materials, infrastructure construction, agriculture, ecological restoration, and new materials. In construction applications, processed gypsum serves as raw material for gypsum blocks, boards, plastering gypsum, mortar, and self-leveling compounds. In cement production, processed by-product gypsum functions as a setting retarder, mineralizer, or as part of co-production processes generating both sulfuric acid and cement clinker.

Through refined deep processing, the company's systems can produce high-end calcium-based fillers including ultrafine anhydrous calcium sulfate and calcium sulfate whiskers, expanding application possibilities beyond traditional construction materials.

Commitment to Sustainable Manufacturing

Liming Machinery's processing lines incorporate closed negative-pressure operation and high-efficiency dust removal systems to prevent dust leakage, wastewater discharge, and harmful gas emissions. The DCS automatic control systems minimize on-site staffing requirements while optimizing operational efficiency.

With nearly 40 years of grinding technology development and extensive project experience, the company provides customized EPC services covering project planning, equipment supply, installation, and commissioning. This comprehensive approach has supported successful gypsum processing projects across multiple regions, establishing benchmarks for large-scale, resource-based utilization of gypsum materials.

Conference Participation and Industry Engagement

The 24th Global Gypsum Conference brings together gypsum professionals from around the world, offering a platform for knowledge exchange, networking, and business development. As a participant in both the conference programme and concurrent exhibition, Liming Machinery will engages with product manufacturers, researchers, plant managers, and technology companies to explore emerging trends in gypsum processing.

Conference delegates interested in grinding technology, calcination systems, and integrated gypsum processing solutions are encouraged to connect with Liming Machinery representatives during the exhibition to discuss project requirements and explore tailored solutions.
