The permanent magnet motor built-in mine hoist jointly developed by Guizhou New Plateau Equipment Co., Ltd. and Taiyuan University of Technology successfully won the international advanced level of scientific and technological achievements appraisal at the scientific and technological achievements appraisal meeting hosted by China Heavy Machinery Industry Association. This major breakthrough marks that China has made significant progress in mine hoist technology, and provides a strong guarantee for the safe and efficient production of the mining industry.

The appraisal meeting was held in Guizhou recently. Tang Renyuan, academician of the Chinese Academy of Engineering, Wang Guofa and many other industry experts participated in the appraisal. The experts listened to the project report, reviewed the relevant technical information, and conducted on-site visits. After a rigorous review, the appraisal committee agreed that the permanent magnet motor built-in mine hoist has a number of technological innovations, and the results have the international advanced level, and agreed to pass the appraisal of scientific and technological achievements.

Permanent magnet motor built-in mine hoist is the crystallization of many years of cooperation between Guizhou New Plateau Equipment Co., Ltd. and Taiyuan University of Technology. The technology began to be developed in 2005. After ten years of unremitting efforts, it was basically successfully developed in 2015 and was put into trial operation in Guizhou Coal Mine in 2016. In 2017, the technology was officially applied to the Guogushan Coal Mine in Guizhou Province, and achieved significant energy-saving and economic benefits.

Compared with the traditional mine hoist, the permanent magnet motor built-in mine hoist has significant advantages. It uses the outer drum of the hoist as the principle of the outer rotor permanent magnet synchronous motor, eliminating the intermediate links such as reducer, coupling, lubrication station, etc., with compact structure, small footprint, low noise and remarkable energy saving effect. Data show that the permanent magnet hoist technology can save energy by 37%, basically maintenance-free, and greatly improve the safety factor, providing strong support for safe production and energy saving and emission reduction in the mining industry.

In addition, the permanent magnet motor built-in mine hoist is also widely used in iron, mercury, aluminum, copper and other metal mining, as well as phosphorus and other non-metallic mining. According to the R & D team, the technology has been applied in more than 50 mines in Guizhou, Yunnan, Sichuan, Chongqing, Shanxi, Xinjiang and other places, and has been highly praised by users.

The person in charge of Guizhou New Plateau equipment Co., Ltd. said that the appraisal of scientific and technological achievements at the international advanced level is an affirmation of the company's efforts in the research and development of mine hoist technology over the years. In the future, the company will continue to increase R & D investment, continuously improve the technical level, and provide more safe, efficient and energy-saving equipment products and services for the mining industry.

The success of this scientific and technological achievement appraisal not only injects new impetus into the development of Guizhou New Plateau Equipment Co., Ltd., but also provides strong support for the transformation, upgrading and sustainable development of my country's mining industry. It is believed that in the near future, the permanent magnet motor built-in mine hoist will be applied in more mines and make greater contributions to the safe production and energy saving and emission reduction of the mining industry.
