On January 24, 2025, at the Xinjiang Shengxiong Energy Technology Hall, Jiangsu Jaung Intelligent Industrial Technology Co., Ltd. (hereinafter referred to as "Jasung Intelligent") and Xinjiang Zhongtai Chemical successfully held a signing ceremony for the specialized low-speed suspended ring energy-saving drive system project for mills. This signing marks a solid step forward in the cooperation between the two parties in promoting energy conservation, emission reduction, and green production, and will jointly pioneer the transformation of domestic grinding equipment's low-speed high-torque drive system to a permanent magnet low-speed suspended ring motor.

Cooperation Background and Project Significance

In accordance with the "National Medium- and Long-Term Scientific and Technological Development Plan Outline (2006-2020)" and the spirit of the speech at the Group Company's 2025 Work Conference and the Eighth Session of the Second Workers' Congress, there is a further strengthening of the business philosophy of "reducing costs and increasing efficiency, and tapping internal growth points to enhance endogenous power."

As an industry-leading innovative enterprise, Xinjiang Zhongtai Chemical continuously seeks breakthroughs in energy-saving and intelligent technology applications, and the cooperation with Jiaxuan Intelligent is based on this strategic need. The collaboration will drive the industry towards a transformation characterized by low energy consumption, high efficiency, and low emissions, supporting the sustainable development of the sector.

The First 3MW and Above Permanent Magnet Low-Speed Suspended Ring Energy-Saving Drive System in the Country

The core project of this cooperation is the transformation of a 3550kW horizontal ball mill. The traditional asynchronous motor-reducer drive mode suffers from low efficiency, high energy consumption, and high maintenance costs. The permanent magnet intelligent ring energy-saving drive system proposed by Jiaxuan Intelligent will fundamentally change this situation. This system features an integrated design of the motor rotor and the mill drum, eliminating complex components such as clutches, gearboxes, large and small gear sets, and lubrication systems found in traditional drive systems. This simplification enhances transmission efficiency and significantly reduces maintenance costs. This system is the first permanent magnet intelligent ring energy-saving drive system in the country with a capacity of over 3MW and represents the largest power permanent magnet low-speed suspended ring motor in the world, marking a significant breakthrough in technological innovation.

Project Advantages and Expected Benefits

After implementation, the project is expected to bring significant production and economic benefits:

1. Improved Efficiency and Quality

The combination of the permanent magnet ring direct-drive motor and the inverter control system enhances transmission efficiency by 13.4%, further improving the production efficiency of the mill.

2. Energy Conservation and Emission Reduction

The intelligent control system automatically adjusts power output based on material quantity, with an expected energy saving of 12%, effectively reducing energy consumption and contributing to environmental protection.

3. Low Maintenance Costs

The simplified mechanical structure reduces the number of maintenance components, improving equipment reliability and achieving continuous fault-free operation.

4. High Power Factor

The power factor of the permanent magnet direct-drive motor reaches 0.96, improving energy utilization efficiency.

5. Ample Starting Capability

The system has full-load starting capability, with the starting torque reaching 200% of the rated torque, solving the problem of heavy-load starting.

Promoting Technological Upgrades in the Industry

Jiaxuan Intelligent's permanent magnet ring motor not only provides innovative energy-saving solutions for the industry but also has broad applicability. This ring motor can be widely used in various mill systems, breaking through the limitations of traditional drive methods and helping various industries achieve more efficient, energy-saving, and environmentally friendly production modes. In the future, it will continue to drive the overall technological advancement of the industry through technological innovation, providing strong technical support for the green transformation of global industry.
