The China Building Materials Machinery Industry Association has officially released the group standard for carbide stud HPGR used in roller presses, driving high quality development in the industry.
As China's manufacturing sector accelerates its transformation toward high-end, intelligent, and green development, cemented carbide pins - a critical foundational component - have reached a new milestone. Recently, the China Building Materials Machinery Industry Association (CBMMA) announced that following rigorous expert review and public consultation procedures, the CBMMA group standard“Cemented Carbide Pin Rollers for Roller Presses” was formally approved and released on February 7th,2026. The implementation of this standard signifies China's advancement toward more targeted and higher-quality industry regulations in the field of core consumables for high pressure roller mills. It will effectively drive cost reduction and efficiency gains in the mining, cement, and metallurgical industries.
It is understood that the standard completed expert review in December 2025, with oversight provided by 23 experts from the China Building Materials Machinery Industry Association, the National Building Materials Machinery Product Quality Supervision and Inspection Center, Jinan University, Beijing University of Technology, and multiple leading equipment manufacturers and end users.
As a critical material crushing equipment, the performance of the high pressure roller mill's core component -the carbide pins -directly determines the equipment's operational efficiency and energy consumption. However, the inconsistent specifications and varying lifespans of pins available in the market have severely constrained the production efficiency of downstream users. The newly released group standard establishes detailed and stringent requirements for critical indicators of column pins, including material composition, microstructure, hardness distribution, impact toughness, and service life.
Industry experts note that the new standard particularly emphasizes the stability of column pins under extreme high pressure conditions, mandating products to possess outstanding wear resistance and fatigue resistance. This will effectively address longstanding pain points such as frequent downtime and maintenance caused by pin fractures and detachment.
Behind the standard's release lies significant technological advancement in the cemented carbide industry. Search data reveals multiple recent innovations emerging within the sector.
Additionally, industry reports indicate that the cemented carbide industry is undergoing profound green transformation by 2026. Recycled tungsten utilization has risen to 41.7%, while widespread adoption of low carbon processes -such as microwave-plasma sintering and AI dynamic temperature control -has reduced production energy consumption by over 30%. These technological advancements provide a solid foundation and technical support for the smooth implementation of the new standards.
The“2026 China Tungsten-Cobalt Hard Alloy Drill Bit Market Specialized Research and Enterprise‘15th Five-Year Plan’ Recommendations Report” indicates that robust demand from PCB manufacturing, aerospace, and high end machining is driving sustained growth in overall hard alloy material requirements. In mining and construction machinery sectors, the application prospects for hard alloy pins are equally promising.
With the new standard's implementation, over the next five years, cemented carbide pins will evolve beyond mere“consumables” into“intelligent functional components.” Integrating digital twin lifespan prediction models and industrial internet platforms, future pin systems will feature condition monitoring and lifespan alerts, enabling predictive maintenance and establishing a closed-loop digital ecosystem encompassing“materials-design-services.”
A representative from the China Building Materials Machinery Industry Association stated:“The release of the group standard‘Hard Alloy Pin Rollers for Roller Presses’ is just the first step. Next, we will actively guide enterprises to benchmark and meet standards, promoting the widespread application of high quality products in the market. Simultaneously, we encourage enterprises to increase R&D investment, leveraging cutting-edge technologies such as ultra-fine-grain hard alloys and nano-composite coatings to further enhance the international competitiveness of China's hard alloy products.”
With the commencement of nominations for the 2026“Mechanical Industry Science and Technology Awards,” a wave of highly influential scientific achievements is anticipated in the field of cemented carbide materials and applications. Driven by both standardization and technological innovation, China's cemented carbide pin industry is advancing toward a new phase of high quality development, contributing a“Chinese solution” to the green and efficient operation of global foundational industries.
Cemented carbide pins are primarily used on the counter-rollers of roll presses. Compared to traditional roll surface surfacing, they significantly enhance wear resistance and extend the service life of roll presses.
Carbide pins for roll presses feature high hardness, high strength, and excellent impact resistance, substantially extending the service life and operational efficiency of roll presses.
Carbide pins are categorized into arc-shaped pins and flat head chamfered pins.
As core wear resistant components of roll presses (high pressure roll mills), the performance of carbide pins directly impacts equipment operational efficiency and enterprise production costs.
