After winning the order for 720 sets of iron removal equipment, Xinding Magnet has a larger "lithium thought"

Two years ago, at the 29th International Rubber Industry Equipment Exhibition in Guangzhou, the purchase order for 720 sets of magnetic pipe filters from Chubb Technology allowed Shandong Xinding Magnet Manufacturing Co., Ltd. (hereinafter referred to as "Xinding Magnet") to inadvertently knock on the door of the lithium battery industry.

After receiving the order, The first reaction of Zhou Haisheng, general manager of Xinding Magnet, was not ecstasy, but felt "unreliable". "Based on past experience, the wet body is equipped with filters, one to two machines per production line is enough, 720 units means at least 360 production lines, this situation has never occurred before, and we initially doubted the authenticity of the order." Zhou Haisheng's clear memories.

In fact, Chubb Technology is a veteran lithium iron phosphate battery cathode material lithium iron phosphate and its precursor - iron phosphate manufacturing enterprises, as early as June 2014 has been successfully listed on the "New Third Board", BYD, Hefei Guoxuan, AVIC Lithium Battery and other enterprises are its important customers, in 2016 Chubb Technology achieved operating income of 912 million yuan, an increase of 339.9%.

After confirming the order, Zhou Haisheng put aside his doubts, but the strong attraction drove him to sign the order. According to Zhou Haisheng, this is the first time in his 11 years of working in the field of magnets that he has discovered the field of iron removal with such high precision requirements, and this order is like a window that suddenly opens, bringing him a new business inspiration.

Taking orders is not Zhou Haisheng's impulsiveness. Xinding Magnet has dozens of technical backbones with more than 10 years of experience in the magnetic industry, as well as perfect and mature equipment, production, installation and commissioning workshop is the cost of Zhouhai's hard air orders.

Although there is a certain degree of psychological preparation, the difficulty of equipment research and development is beyond Zhou Haisheng's expectations. First, the market gap. There are few companies engaged in lithium battery iron removal business in China, lack of technical reference experience and data references; second, it is impossible to quantify the standards of products. The amount of iron content of the material is the core secret of the raw material enterprise, and the data information is highly confidential, so it is impossible to understand the product compliance through the data in this aspect.

On the one hand, the high-precision requirements of the finished equipment put forward by the customer, on the other hand, there is no reference for reference, and the Xinding magnet of "the first crab eating" in the field of lithium battery iron removal is difficult. "To complete the relationship definition and distribution ratio of the equipment according to the schedule, there is no choice but to repeatedly test and reverse the accuracy of the iron removal through the test data of the iron removal equipment." After several overnight operations, 5 "big tests" (debugging in the case of the overall installation of iron removal equipment) and countless "small tests" (single tests), Xinding Magnet finally delivered the iron removal filtration equipment on schedule. The customer's evaluation after debugging and use is: "Very satisfied! ”

Repeated debugging consumes a lot of manpower and material resources, but it also makes Xinding magnet harvest. In 2016, Guizhou Anda iron phosphate, lithium iron phosphate expansion, Xinding magnet became the only supplier of Guizhou Anda iron removal equipment, coupled with the 2016 lithium battery market blowout outbreak, Xinding magnet produced lithium battery iron removal equipment once in short supply. In the same year, the revenue of Xinding Magnet Lithium Battery Deferension Business accounted for 30% of the total revenue. At the same time, Xinding Magnet has also become the only magnetic equipment enterprise in China to grasp all the data of the first line of electromagnetic iron removal of iron phosphate powder.

"The debugging process is difficult and cumbersome, but it is in the continuous debugging process that we understand the size of the magnetic floating space of the lithium battery cathode material, determine how to allocate the upper, middle and lower magnetic fields to ensure that the iron removal is qualified, and it is no exaggeration to say that every drop of iron phosphate comes out we are clear, these are exclusive and priceless information." In my opinion, Xinding Magnet boldly explores the harvest of lithium battery iron removal far more than the pay. Looking back on the research and production process, Zhou Haisheng is not without emotion.

At present, Xinding Magnet has launched four main products for the lithium battery industry: wet grinding slurry permanent magnet iron removal system, slurry electromagnetic automatic iron removal machine, permanent magnet automatic dry powder iron removal machine and electromagnetic automatic dry powder iron removal machine. Among them, the magnetization technology of rare earth permanent magnet material is the concentrated embodiment of the advantages of Xinding magnet technology, and its invention of "spherical magnetization technology" can not only enhance the magnetic field stability of magnetic materials, but also increase the penetration of magnetic depth by more than 2 times.

In fact, Xinding Magnet was established in December 2014, compared to other established magnet companies appear very young, but in just two years, Xinding Magnet has achieved the rational utilization of the two major magnetic systems by virtue of permanent magnet and electromagnetic technology and intelligent control means. And in 2015, seizing the opportunity of the development of the lithium battery industry, we successfully transformed into the first batch of traditional iron removal and lithium battery iron removal double-line development of magnetic equipment customization enterprises in China, and became a provincial key leading enterprise specializing in the integration of magnet production, processing, manufacturing, research and development, and sales.

It is this youth that gives Xinding Magnet more innovation and exploration genes:

Through extensive attention and utilization of online Internet resources, Xinding Magnet harvested the company's first bucket of gold, a strong magnetic plate order from a mechanical and electrical equipment sales company in Hengshui, Hebei Province;

By taking the lead in the lithium battery iron removal business, Xinding Magnet put forward a two-way development strategy of traditional magnet business and emerging industries, and the traditional magnet business has steadily increased, and the proportion of revenue of lithium battery iron removal business has reached 30%, with rapid growth;

In view of the standardization trend of lithium battery industry, Xinding Magnet innovatively put forward the concept of standardization of custom enterprises, and has launched the dry line iron removal equipment XDDZ-152P automatic electromagnetic dry powder iron removal machine, micro powder electromagnetic dry powder XDDC-302P iron removal machine, wet line iron removal equipment XDYG-50S, which has effectively promoted the standardization process of non-standard custom enterprises.

This dare to fight the momentum so that Xinding Magnet "from small to large" accumulated many loyal customers, in 2016 Xinding Magnet operating income successfully crossed the 60 million yuan mark. In 2017, the sales of Xinding Magnet continued to rise steadily in the first quarter, and it is expected that the annual sales will reach 90 million yuan.

"In 2017, we will continue to use this 'hard work' to do more things in the field of lithium battery iron removal." Zhou Haisheng said firmly: "In 2015 and 2016, the focus of Xinding Magnet in lithium battery iron removal was more focused on learning and accumulation, but in 2017, we believe that the time is ripe to take the next step."

The first is to increase investment in equipment intelligence. From the current trend point of view, lithium battery industry requirements for battery energy density will be higher and higher, will inevitably put forward more stringent requirements for iron removal equipment, Xinding magnet will meet the requirements of different quality materials for magnetic field, magnetic depth at the same time, strengthen the production line, equipment intelligence, degree of automation, reduce the impact of human factors, to ensure the consistency of material batch quality.

The second is to combine the trend of scale and standardization of the lithium battery industry, strengthen cooperation and communication with lithium battery equipment industry chain enterprises, improve data docking, further enhance the compatibility of iron removal equipment, and open up a wider extension space in equipment control and magnetic circuit combination to meet the iron removal needs of different enterprises and a variety of battery materials and process paths. ”

With the adjustment of new domestic policies and the further release of lithium battery production capacity, the safety and energy density of batteries have attracted more and more attention, and iron removal technology has also played an increasingly important role in hot areas of public concern because it can ensure the purity of battery materials.

In terms of ensuring the safety of the battery, lithium battery iron removal technology and equipment ensure the stability of the chemical substances inside the battery and improve the overall operation safety of the battery by controlling the metal pollutants inside the battery within a reasonable range. In terms of energy density, the importance of material purity is even more self-evident.

Usually, in order to achieve the best iron removal effect, it is not only necessary to control the magnetic force of the iron removal equipment, but also to measure and match the magnetic depth data according to the characteristics of the magnetically separated substance. However, there is a shortage of talents in the industry who truly understand lithium battery iron removal technology, and passive iron removal has become the norm in the industry.

In fact, the cost of iron in addition currently accounts for only about one-twentieth of the cost of lithium battery material production lines, but ignoring this twentieth will not only cause a waste of battery resources, affect the energy density of the battery, and may even cause serious safety hazards.

"Enhancing the understanding and attention of the lithium battery industry to iron removal, meeting the higher precision requirements of lithium battery iron removal by promoting the industry's artificial intelligence, automating the process, and configuring integrated control systems for lithium battery enterprises will be the focus of xinding magnets in the next stage."

Zhou Haisheng is full of confidence in the future development of Xinding Magnet in the lithium battery industry: "We must do a good job in 'technical control' and 'service control', while continuing to specialize and deepen the technology in the field, providing the top service for all links and enterprises with magnetic separation needs in the lithium battery industry chain will be our long-term commitment." ”
