In 2026, the global market for Semi-Autogenous Grinding (SAG) mills is experiencing steady growth. Key trends include increased scale, enhanced intelligence, and greater energy efficiency, while Chinese-manufactured equipment is rapidly making inroads into the high-end market segment.
I. Market Size and Demand
Global Market: In 2026, the market size stands at approximately US$490 million, with an annual growth rate of 2.92%.
China Market: The market is valued at approximately RMB 4.8 billion; this figure is projected to exceed RMB 7.5 billion by 2030, representing an annual growth rate of 11.8%.
Demand Hotspots: Production expansion at metal mines—particularly those extracting copper, gold, and iron—is driving demand, while the "Belt and Road" Initiative and various overseas projects are fueling a surge in export orders.
II. Cutting-Edge Technological Breakthroughs
Ultra-Large Scale: Domestically produced mills have reached a maximum diameter of 12.5 meters and a power output of 18,000 kW, with the processing capacity of a single unit exceeding 10,000 tons.
Intelligent Control: Features include multi-sensor fusion monitoring (with an error margin of less than 3%) and AI-driven load optimization, resulting in a 12.4% reduction in electricity consumption per ton of ore processed.
Wear Resistance Upgrades: The adoption of high-alloy forged liners and composite wear-resistant materials has extended service life by over 50%.
Green and Energy-Efficient: Technologies such as variable frequency drives, digital twins, and low-carbon manufacturing processes have reduced carbon emissions by over 30% compared to traditional methods.
III. Industry Dynamics and Orders
Metso: Secured a €39 million order from Canada, which includes an ultra-class 18,000 kW SAG mill.
Daming Heavy Industry: Delivered a 12.5-meter-diameter SAG mill to South America, with its order book now filled through the second half of the year.
Northern Heavy Industries: Exported an 8.8-meter-diameter SAG mill to the Middle East, demonstrating a level of performance that meets advanced international standards.
IV. 2026 Trend Outlook
Product Direction: Ultra-large-scale mills (10m+ diameter), intelligent sensing capabilities, predictive maintenance systems, and low-carbon certification are becoming standard features.
Competitive Landscape: Domestic manufacturers are rapidly displacing imported products, with companies such as CITIC Heavy Industries, Northern Heavy Industries, and Daming emerging as global leaders.
Application Expansion: Mills are being adapted to process low-grade and complex ores; furthermore, they are increasingly being integrated with High-Pressure Grinding Rolls (HPGR) to serve as core equipment in green mining operations.
