Angang Mining Machinery Manufacturing Co., Ltd. – Long-term Supply Partnership for Steel Ball Rolling Rolls
Angang Mining Machinery Manufacturing Co., Ltd. is a core subsidiary of Angang Group responsible for the manufacture of mining machinery. Since 2020, Shenyang Muren Machinery Co., Ltd. has served as a key supplier of steel ball rolling rolls and related products to the company.
Throughout the partnership, Muren Machinery has successfully won multiple tenders for the supply of various roll specifications, including rolls for diameters of 20mm, 25mm, 60mm, and 80mm. The company frequently secured these contracts by ranking first among bidders in public tenders. In 2026, the partnership deepened further when Muren Machinery undertook the "functional guarantee service" project for Angang's 80mm ball rolling rolls, providing comprehensive, full-lifecycle support ranging from product supply to operational assurance. In 2024, the company also provided laser-cutting processing services-such as for drainage grates-to Angang.
Furthermore, Muren Machinery's repeated top rankings in Angang's tenders for steel ball rolling rolls demonstrate its superior product quality and delivery capabilities.
The two parties have established a long-term, stable strategic partnership.

In January 2026, Muren Machinery successfully won the bid to supply grinding steel balls to Inner Mongolia Sulige Gas Power Generation Co., Ltd., a subsidiary of Inner Mongolia Energy Group Co., Ltd. Inner Mongolia Energy Group is a key enterprise in the energy sector of the Inner Mongolia Autonomous Region; this collaboration has strengthened Muren Machinery's track record in the power industry and demonstrates the company's service capabilities in supplying grinding media to the thermal power sector.
Yichun Luming Mining – Equipment Retrofitting and Full-Lifecycle Maintenance Services
Muren Machinery has established a deep partnership with Yichun Luming Mining, a subsidiary of China Railway Resources. The company provided Luming Mining with a comprehensive suite of services, including equipment retrofitting, supply of critical spare parts, equipment maintenance, and non-destructive testing, covering the entire process from initial design to on-site implementation.
During the collaboration, Muren Machinery resolved various technical challenges encountered during equipment operation; through the timely supply of critical spare parts and professional maintenance services, the company effectively ensured the continuity of the mine's production operations. This case demonstrates the company's full-lifecycle service capabilities in the field of mining equipment maintenance, as well as its ability to respond quickly to specific customer needs.
Molido Iron Mine, Peru – Export of First Crushing and Screening System
In 2018, Muren Machinery designed and manufactured its first complete crushing and screening system for the Molido Iron Mine in Peru, marking the company's entry into the overseas market. Tailored to the mine's specific ore characteristics and production requirements, the system covered the entire process flow from crushing to screening. Following delivery, the system operated reliably and earned initial recognition from the client; this success established the company's international brand presence and laid the foundation for future overseas market expansion.
Expansion into the Russian Market – Establishment of Moscow Office
In 2025, Muren Machinery officially established an office in Moscow, Russia, marking a new phase in the company's internationalization strategy. Prior to this, the company had already supplied a wide range of products to the Russian market-including multi-head steel ball rollers (diameters Φ20, Φ25, Φ30, Φ60) and single-head steel ball rollers (diameters Φ50, Φ80, Φ89, Φ100)-covering a complete product line from small and medium sizes to large-scale specifications. The establishment of the Moscow office will further enhance the company's service response speed and technical support capabilities for the Russian-speaking market.
Cement Plant in Hebei – Cost Reduction and Efficiency Improvement via Grinding Media Replacement
A cement plant in Hebei originally used cast balls as grinding media for its cement mills; however, high wear rates and the need for frequent ball replenishment resulted in consistently high overall operating costs. Muren Machinery provided a replacement solution using cross-rolled steel grinding balls. The cross-rolling process eliminates defects such as blowholes and voids found in cast balls, resulting in a uniform grain structure that makes the product resistant to cracking or fracturing during use.
Actual operational data showed that switching to Muren Machinery's rolled balls significantly reduced wear rates compared to cast balls, substantially extended the replenishment cycle, and improved grinding efficiency-resulting in annual savings of approximately $12,000 on grinding media alone.
