China successfully developed the world's largest and most advanced ball mill

On July 1, the largest and most advanced overflow ball mill independently developed by China and fully possessing independent intellectual property rights was successfully tested at the production site of CITIC Heavy Industry Machinery Co., Ltd. This indicates that China's large-scale mill technology has broken the global monopoly of high-end grinding equipment technology and market by a few international companies in just a few years.

According to Ren Xinxin, the general manager of CITIC Heavy Industries, the successful φ7.93×13.6m overflow ball mill was the first group of 6 sets of mills of the Australian SINO iron ore project won by CITIC Heavy Industries in August 2007. equipment. The ball mill is fully implemented in accordance with international standards in terms of design, material selection, manufacturing process and inspection, and has achieved major breakthroughs in structure and technology. The bearing adopts self-aligning and multi-sliding support, super-power double-machine drag and automatic hydraulic drive. It is the ball mill equipment with the largest international specifications, the highest equipment configuration and the most complete control performance. CITIC Heavy Industries will provide 6 sets of 12 world's largest and most advanced self-grinding mills and overflow ball mills for independent R&D and manufacturing projects to serve the first phase of the iron ore construction project.

In the field of large-scale metal mine beneficiation engineering, energy costs and ore grades have declined, and the mining industry in various countries in the world is facing a severe test. Large-scale mining mills can effectively solve the mining and scale production problems of low-grade mines with high output and high reliability. The Australian SINO iron ore project, which is built by the China Metallurgical Science and Technology Group, is one of the largest iron ore projects in the world. It has high requirements for its core equipment, self-grinding mills and ball mills. Zhao Debao, general manager of MCC Western Australia, said that after comprehensive inspection and multi-party demonstration by the owner and the general contractor, CITIC Heavy Industries chose to independently design, develop and manufacture six large-scale self-grinding mills and overflow ball mills. Today, the first billiard mill was delivered to the factory, which enabled domestic and foreign mining companies to have greater confidence in Chinese equipment.
