Recently, the 18th China International Coal Mining Technology Exchange and Equipment Exhibition came to a close at the Beijing International Exhibition Center. As an important event in the coal industry every two years, this exhibition attracted nearly 600 exhibitors from 19 countries and regions around the world. There are many equipment and technologies at this exhibition, but Jiaxuan's newly released "air-cooled permanent magnet drum" is particularly eye-catching. According to relevant sources at Jiaxuan, Jiaxuan's booth attracts a large number of people from home and abroad to visit and consult every day, and the amount of on-site intentional orders has reached 200 million yuan. It is worth noting that Jiaxuan's release of the "air-cooled permanent magnet drum" has not been fully marketed, but it has aroused unprecedented market response. What exactly is an air-cooled permanent magnet drum? Why does the coal industry favor this technology so much? Why does Jiaxuan create a new sales "miracle" in the industrial field? Let us find out!

What exactly is an air-cooled permanent magnet drum?
"The permanent magnet electric drum is actually a permanent magnet motor. It is a shaft with a coil to form a stator, and a copper body plus permanent magnets to form a rotor, which is the opposite of our ordinary motor. The permanent magnet outer rotor is used for direct drive. The Jiaxuan permanent magnet intelligent roller with transmission technology requires only one roller to drive the conveyor. It has a very simple structure, saves valuable underground space, and has the characteristics of high efficiency and energy saving and improved equipment safety." Zhang Bochao, general manager of Shanghai Coal Science Testing Technology Co., Ltd., said in a speech at the Jiaxuan new product launch conference. The first permanent magnet drum adopts the "air-cooled" mode, which is another innovation of the "permanent magnet drum", because it reduces the water cooling water channel, water cooling filter and other equipment, which takes up less space and has a lower maintenance rate. The production efficiency is further improved. The emergence of permanent magnetic drum technology has greatly optimized today's coal drive system, and has greatly promoted the industry trends of "intelligent mines" and "unmanned mines". There are even many coal enterprise leaders who call it the third technological revolution of coal underground equipment, which shows the far-reaching impact of this technology in today's coal industry.

Hundreds of coal companies use Jiaxuan permanent magnetic drums

    Just before Jiaxuan released its new air-cooled permanent magnet drum product, hundreds of companies in the entire coal industry had adopted permanent magnet drum technology. According to Jiaxuan's introduction, Jiaxuan permanent magnet rollers have been sold to more than 20 provinces, municipalities and autonomous regions, and more than 40 prefecture-level cities across the country. Currently, there are hundreds of large central enterprises and state-owned enterprises using Jiaxuan permanent magnet rollers. There are also many small and medium-sized coal companies that are joining this iterative reform of the driving system. This brand-new product, which came out less than 3 years ago, has set off a lot of storms in the coal industry, and it also shows that the intelligent trend of the coal industry is getting deeper and deeper.

　　The secret of the popularity of Jiaxuan's permanent magnetic roller technology is not mysterious, behind it is the persistent pursuit of safety and innovation. It is understood that Jiaxuan has successively obtained 106 national safety standard certifications, the world's first 315KW explosion-proof certification, and was selected into the national industrial energy-saving technology product catalog, becoming the permanent magnet roller industry standard setter. As the industry leading brand of permanent magnet technology, Jiaxuan's permanent magnet roller products won the first prize of the Jiangsu Industrial Innovation and Entrepreneurship Competition and one of the three Jiangsu intelligent equipment companies recommended by Jiangsu Province to participate in the first (Chongqing) International Smart Fair.

　　The orders that have not yet been listed have reached 200 million, how did Jiaxuan air-cooled permanent magnet drums do it?

　　In an interview with reporters, Jiaxuan Chairman Fu Jie mentioned that Jiaxuan began to study permanent magnet motors in 2013, and the period between 2013 and the end of 2016 is the research and development period. This process is very torturous for the company, and it is constantly adjusted and imitated. . After the official listing in 2017, the market feedback is very good, and we are very pleased. By mid-to-late 2018, after our first installation certificate was obtained, it was the world's largest installation certificate of 315 kilowatts, and orders were successively generated. The real difficulty is the repeated verification and experimentation in the research and development stage. During the entire promotion process, there was basically no artificial promotion, and basically customers took the initiative to come to the door.

　　Good technology and products always have a natural attraction. The air-cooled permanent magnet drum released this time has also attracted the attention of many coal industries around the world. The product has not yet been officially launched, and Jiaxuan has received an order of 200 million yuan. Not only that, this innovative technology has now gone abroad, and currently Russia and Kazakhstan have reached cooperation with Jiaxuan. In the future, after obtaining the common safety standard certification with Russia, it will also customize and sell in the Middle East. Why is the permanent magnet roller favored by the international convenience? It turns out that this technology was first applied in China. Although this technology has existed abroad for a long time, the domestic technology application is

　　The most mature and safest, and Jiaxuan is the most professional manufacturer of permanent magnet rollers.

　　When the reporter asked about market competition, Fu Jie was quite confident, “As one of the industry standard setters for permanent magnet drums, Jiaxuan can currently cover the entire industry with permanent magnet drums of all diameters and powers, and our All permanent magnet motors have obtained the national safety standard certification, and are currently the only one in the entire industry. We also have a permanent magnet motor testing and test bench. This equipment is currently only one in the world. Anyone in the industry is free and open. It meets the company's safety and technical standards, and we can all do inspections for them."

Fu Jie was interviewed by the media at the press conference

At present, Jiaxuan, as a leader in the permanent magnetic drum industry, not only pays attention to its own corporate development, but is also actively promoting the positive and healthy development of the industry. Jiaxuan has also reached a "production-study-research" alliance with a number of institutions in the coal industry, investing 7-8% of scientific research investment in technological innovation every year. Strike iron still needs its own hard work, and Jiaxuan's ability to obtain high recognition from the coal industry is closely related to its own technological leadership. In contrast to the entire coal industry, when everyone is holding high the banner of technological innovation, many policies and technologies will inevitably fall into the void, and the technology that can actually improve the production and safety efficiency of enterprises is the most precious. Today, Jiaxuan's air-cooled permanent magnet drum has achieved staged market success is just a starting point. Whether it can bring more advanced technology to the coal industry in the future and whether it can continue to promote the intelligent transformation of the coal industry is a question worthy of our continued attention.
