On April 30, 2025, the commissioning of the 3# raw material ball mill of the third phase project of Bintan Alumina Co., Ltd. in Indonesia was successfully completed, and the belt was fully connected, laying a solid foundation for the overall production of the project.

As a core equipment, the raw material ball mill has a complex structure and a large volume, and the commissioning process faces extremely high professional requirements. The company has formulated a careful plan, started the equipment in steps, and monitored the operation data in real time and adjusted it dynamically throughout the process to ensure safe and efficient commissioning. During the construction phase, the project team overcame difficulties such as complex local geology, long rainy season and tight construction period, scientifically allocated resources, strengthened the supervision of key processes, and ensured that the equipment was put into use as scheduled.

As the "first button" of the commissioning of the third phase alumina project, the smooth operation of the raw material ball mill and the belt marks the official start of the commissioning of the entire production system. At present, the entire set of alumina production processes is being gradually promoted according to the established nodes and put into production on schedule. The success of this trial run fully demonstrated the company's technical capabilities and project management level, and also highlighted Nanshan's work philosophy of "advocating dedication, pursuing excellence, unity and cooperation, and seeking truth and being pragmatic", injecting strong impetus into the subsequent release of production capacity and industrial upgrading.
