Sichuan has the largest gold mine in the province. The mining site is located on the top of a peak at an altitude of 4,200 meters. The air is thin and the oxygen content is only 60% of that in the plains. The extreme climate conditions also bring huge challenges to the mining work.

In order to improve the efficiency and production capacity of gold mining, the Sichuan Gold Renovation Project decided to implement technical transformation of the existing crushing line. The core goals are to expand the processing capacity and reduce the grinding size of the ore. In the fierce competition from many well-known domestic and foreign companies, Shibang Group's solution stood out due to its excellent performance. It innovatively upgraded the original "C100+GP11F two-stage one closed circuit, output -18mm particle size" old process to a three-stage one consisting of "C100+HST160 (H1) high-efficiency primary crushing + HPT300 (F2) fine secondary crushing" "Closed-circuit system" achieves product particle size accuracy as low as -12mm, which not only greatly improves the processing capacity, but also effectively reduces the particle size of the ore before entering the grinding mill, laying a solid foundation for subsequent grinding operations and significantly optimizing the production process and economic benefits. .

After the technical transformation and upgrade, actual production and operation have verified that Shibang's technical transformation plan and equipment have fully achieved the customer's requirements for increasing crushing and screening capacity before grinding and reducing grinding particle size, and have been highly praised by customers.
