Shanghai, July 7, 2025] SHANGHAI GAOLV MAGNETIC POWER TECHNOLOGY CO.,LTD. is oriented to customers' needs, and its permanent magnetic coupling technology has emerged as several benchmark cases in the intelligent transformation of mining industry, promoting the industry to upgrade to “predictive maintenance”.
Case 1: Shanxi Linfen Coal Processing Plant -- Intelligent Innovation Driven by Multi-machine Collaboration
Challenge Scenario: The three belt transportation lines in this coal processing plant originally used rigid couplings, and the load deviation of the three motors was often up to 15%, which led to frequent belt deflections and tears, and the annual cost of replacing the belts exceeded 800,000 RMB.
Gaolv’s solution: Deploy Gaolv permanent magnet coupling and integrate intelligent load balancing system in 2024:
● Real-time adjustment of the torque of each motor, load deviation control within 3%;
● Belt tension fluctuations from ±12% to ±5%, belt life extended by 3 times;
● Built-in sensors to monitor the temperature and torque in real time, through the PLC system to warn of failures in advance, in the second half of 2024, there was not a single drive system downtime due to the transmission system caused by the second half of 2024 without a single downtime.
The result of the transformation: the annual cost of belt replacement is saved 620,000 RMB, the number of operation and maintenance personnel is reduced from 8 to 3, and it is selected as the demonstration project of intelligent mine in Shanxi Province.
Intelligent Drive: Multi-machine Collaboration and Fault Early Warning
The application case of hoist system in Jining Coal Mine in Shandong further verified the reliability of the technology - through the soft-start characteristic of Gaolv permanent magnet coupling, the peak motor starting current was reduced from 1200A to 780A, and the impact on the power grid was reduced by 35%, which was honored as “Coal Mine Mechanical and Electrical Equipment” by the National Energy Administration (NEA). It was certified by the National Energy Bureau as “Excellent Case of Coal Mine Electromechanical Equipment Energy-saving Retrofit”.
Case 2: Henan Anyang Iron Ore Mine - A Cost Revolution with 5-Hour Extreme Retrofit
Time Pressure: The iron ore mine needs to complete the crusher coupling retrofit during the shutdown and maintenance period, and the traditional solution takes more than 12 hours, which may affect the subsequent production plan.
Gaolv’s Advantage: The Gaolv PM coupling adopts a modular design, eliminating the need for precise alignment:
● Installation time was reduced to 5 hours, a 58% increase in efficiency over traditional solutions;
● Does not need to replace the original motor and reducer, which reduces the retrofitting cost by 32%;
● Vibration value is reduced from 6.8mm/s to 2.1mm/s, and the temperature rise of the bearing is reduced from 42℃ to 28℃ after it is put into operation.
The project leader commented, “The Gaolv's‘plug and play’design allowed us to complete the retrofit ahead of schedule within the overhaul window, boosting production by 12% year-on-year in the current quarter, which was unthinkable in the past.”
Convenient Installation: Rapid Deployment Reduces Retrofit Costs
In the screen machine retrofit of Xinjiang Hami Copper Mine, the Gaolv PM coupling even set an industry record of “3 hours installation + 2 hours commissioning”, helping the mine to quickly resume production in the event of an unexpected shutdown and reducing losses by more than 500,000 RMB.
Case 3: Sichuan Mabian Phosphorus Mine - Green Practice under the Double Carbon Goal
Policy landing: the mine needs to achieve carbon emission reduction of 15% by 2025, and the 12 flotation machines in the whole mine will be retrofitted with Gaolv permanent magnetic couplings in 2024:
● Single equipment annual power savings of 120,000 degrees, the annual carbon reduction of the mine 12,000 tons;
● Oil-free design to eliminate hydraulic oil leakage pollution, won the title of “Cleaner production demonstration project” by the Sichuan Provincial Environmental Protection Department;
● Combined with the intelligent monitoring system, the energy consumption data is uploaded to the supervision platform of the local Development and Reform Commission in real time, which has become a benchmark in the phosphorus chemical industry.
Policy Fit: Helping Mines Reach the Double Carbon Goal
The practice of Yunnan Kunming Bauxite Mine is also eye-catching - through the synergy of Gaolv permanent magnetic couplings and photovoltaic power supply system, the mine realizes 100% clean energy coverage of the transmission link, and becomes the first “zero-carbon transmission mine workshop” in China.
