"Chinese goods should be self-improvement" is not an empty cry. Finding a breakthrough in the field of high-end manufacturing is the most important task of China's mining and metallurgical equipment enterprises.

On June 3, in the production workshop of Jinyang Metallurgical Mining Equipment Company (hereinafter referred to as "Jinyang Mining Machinery") in the advanced manufacturing base of Baishazhou Industrial Park, Hengyang City, Hunan Province, a cylindrical equipment nearly 4 meters high and dark blue outer body is undergoing trial run. Accompanied by the motor sound of the high-speed rotation of the pulley, pieces of ore of different sizes will be automatically transported by the crawler to the cone to be broken.

This is the first domestic large-scale cone crusher JY800 tailored by Jinyang Mining Machine for Jiangxi Copper.

The test results show that the operation of the equipment is fully consistent with the design requirements. Jinyang mining machine has achieved a major breakthrough in the localization of large-scale high-end cone crusher equipment, filling the domestic gap, which is eye-catching.

In fact, this is not the first time that Jinyang mining machine has made a breakthrough.

The last breakthrough was in 2014. Jinyang Company took the lead in developing the domestic complete machine of JY500 cone crusher, which has withstood the use inspection of Jiangxi Copper, China Gold Group and other users. It is the only equipment supplier in China that has withstood the market and time inspection of large-scale domestic cone crusher. And JY800 is a new technology height, from JY500 to JY800 is by no means a simple leap. The internal hydraulic system is not the same, the technical parameters are not the same, especially the new technical parameters in the whole system to be consistent with each other, to maintain the high-speed operation of the equipment, in addition to the entire automatic control system software program also needs to be rewritten. "The high-end cone crusher has achieved localization and industrialization, which means that Jinyang has become one of the few companies in the world that have mastered this technology." This is what Zhou Nong, secretary of the Hengyang Municipal Party Committee, said after inspecting Jinyang Company.

For a long time, the high-end cone crusher produced by domestic mining has been monopolized by several foreign companies. The ore crusher has high strength, heavy load, and almost all-weather operation. It is extremely picky about the durability, stability and endurance of the equipment. There is a big gap between Chinese enterprises and advanced foreign companies in the manufacturing quality, reliability and service life of high-end cone crushers. But now, a private small and medium-sized enterprise has broken the monopoly of foreign companies for many years, and pushed the Chinese national cone crusher brand to a new height.

The localization evolution from core components to complete machines is different from the growth route of most private manufacturing enterprises' products with low technical content, which are good at winning price wars on a large scale. It is also different from the state-owned technical equipment manufacturing enterprises such as Xu Gong and Erzhong, which are naturally supported by national policies. Jinyang Mining Machine was born at the grassroots level, but from the first day of its birth, it has been bleeding with technological innovation. Jinyang mining machine selects the core parts of cone crusher with high technical content, and evolves step by step from the localization of core parts to the localization of the whole machine. It can be said that the growth process of Jinyang mining machine is a microcosm of China's equipment manufacturing industry from small to large, from parts to complete machines, from digestion and absorption to China's creation.

In the early years, Jinyang Mining Machinery was busy fighting overseas and had no time to take care of the domestic market. Its products were supplied to the main accessories of cone crushers for users of large overseas mining enterprises. It first developed the ability to "go out to sea" to participate in international market competition and conquered mining companies in advanced industrialized countries with high quality accessories.

One of the fist products of Jinyang mining machine exported overseas is the copper sleeve on the cone crusher. This is not a general copper sleeve, the quality of this type of copper sleeve produced by many domestic metallurgical machinery enterprises is not satisfactory, and it is easy to crack when assembled on a cone crusher. The material of the copper sleeve is not pure copper, but alloy copper cast with special materials. Yang Jian, chairman of Jinyang Company, said that the difficulty in manufacturing copper sleeves lies in alloy casting. Besides copper, other metals should be added. However, it is difficult to produce qualified copper sleeves without experienced professional companies, such as which metals are added, how much they are added, and how much smelting temperature they are controlled.

In addition to the copper sleeve, Jinyang Mining Machine has also overcome the technical difficulties of other core components of the cone crusher, such as the main shaft and eccentric sleeve, and sold them to the world.

However, the Jinyang mining machine, which "blossoms inside the wall and fragrances outside the wall", is not willing to be a loner who has been floating overseas for a long time. In the world's most dynamic mining producer, China's mining machinery business opportunities are numerous, Jinyang mining machinery hope to bring technical advantages, return to the domestic mining machinery market.

Coincidentally, Jinyang mining machine encountered the same looking for cone crusher localization accessories Jiangxi Copper Group.

Dr. He Labai, a well-known management consulting expert in the non-ferrous mining industry, said that after the loss of imported equipment parts, the purchase of original parts from foreign companies is not only expensive, but also has a long procurement cycle, resulting in an increase in reserve funds. It is understood that for a long time, Jiangxi Copper Industry has vigorously promoted the localization of spare parts in order to reduce the comprehensive procurement cost, shorten the procurement cycle, and actively promote the localization of complete equipment, for this reason, Jiangxi Copper is actively looking for cooperation with Chinese mining machinery manufacturing enterprises.

Jiangxi Copper Industry has given Jinyang Mining Machine, which is eager to open the door to the domestic market, a rare opportunity to agree to use the accessories produced by Jinyang Mining Machine. However, it has put forward a strict condition. It will be tried for half a year first and then paid if it is qualified. After hearing this, Yang Jian confidently promised, "Don't say half a year, that is, if there is a quality problem in the trial year, I don't want a penny." The so-called art master's boldness, behind Yang Jian's boldness, is his full confidence in the quality of Jinyang mining machine products.

The accessories provided by Jinyang Mining Machine to Jiangxi Copper Industry are not only comparable in performance and quality to those of western multinational companies and reach the technical level of similar imported accessories, but also the products are affordable and, more importantly, fast delivery and convenient procurement. Mr. Xiao, deputy general manager of Jinyang Mining Machinery, said, "If the user customizes the parts, the goods will be delivered in more than one month. If there is no need for customized standard parts, the goods are available in the warehouse, and the goods can be delivered after ordering at that time."

In this way, all parts of the cone crusher produced by Jinyang mining machine have entered the Jiangxi copper equipment procurement system, laying the foundation for the development of the whole machine. The high-end cone crusher is just one step away.

However, this last step is not easy to take. The development of the whole machine is mainly difficult in the innovation of integrated technology and the matching of different parameters of parts and components in the same system with high strength and long time operation. Mr. Xiao said, "The matching of the working parameters of JY500 is designed and worked out by ourselves. For example, we have tested the swing of the moving cone for at least half a year, and we have tested it for more than ten times, constantly correcting the swing angle of the moving cone."

What is commendable is that Jinyang mining machine has its own unique understanding of ore crushing technology. In some aspects, it does not adopt internationally consistent technical solutions, but innovates according to its own experience. Straight bevel gears are usually used in the world, but the technical team of Jinyang Mining Machine believes that straight bevel gears are not as stressed as arc teeth and have large noise, so the design is changed to arc gears. "Arc teeth can have three bearing forces at the same time, which is better than straight teeth, and the noise is also reduced." Mr. Shaw said.

He Labai said that Jinyang Mining Machine began to produce cone crusher accessories in 1997 until the successful development of high-end complete machines in 2014. It was easy first and then difficult, innovated step by step, never gave up the pursuit of quality, climbed the height of technology, and gradually accumulated the domestic manufacturing capacity of high-end complete machines.

The secret of the counter attack, Jinyang Mining Machine, started its business by exporting overseas. The first business was export orders. The overseas business has been carried out for 20 years, especially before returning to the domestic market in the first 10 years. And every overseas order, every product sent to foreign mining enterprises, must accept a set of foreign supervision management process, in strict accordance with foreign products quality control methods and technical requirements of production.

In a sense, the long-term implementation of the management model of foreign supervision has brought about a radical change in the production management system of Jinyang Mining Machinery. From the beginning of the company's birth, it has been integrated into the management genes of multinational companies that control high quality. In the process of long-term cooperation with foreign investors and accepting foreign supervision, Jinyang Mining Machinery has learned what "pursuit of perfection" is in product manufacturing and how to pursue perfection management methods. However, most Chinese enterprises, whether state-owned or private, lack the lesson of long-term acceptance of foreign supervision. Compared with multinational companies, there is a certain gap in product quality. This is also an important reason why Jinyang Mining Machinery, a small and humble company, stands out in the field of high-end cone crushers.

Mr. Wang, general manager of Jinyang Mining Machinery, said that in order to obtain products with reliable quality and meeting the requirements, foreign businessmen sent engineers to China to station in enterprises to supervise the production. The management methods, processes and management concepts they brought have greatly promoted Jinyang Mining Machinery. effect. He summed up three profound changes brought to Jinyang mining machinery by foreign supervision. "First of all, foreign supervision pays attention to standardization, determines product standards in the contract, and then supervises production enterprises to strictly follow the standards stipulated in the contract. Secondly, foreign businessmen monitor the whole process from raw material procurement to every production link, while Chinese enterprises often set up inspection at the last level before the products leave the factory. From the practice of foreign businessmen, we have learned that products are produced, not tested. Finally, foreign businessmen use professional testing equipment to supervise the production, such as internal flaw detection, just like our human health examination to do CT, to check the internal quality of products, whether there are defects in machinery and equipment, and to check the composition of materials."

Mr. Xiao said that at the technical preparation stage of each component and the whole machine, the relevant personnel have made a detailed analysis of the drawings and processes, and worked out the quality inspection outline and inspection form according to the principles of general procedures, key procedures and key procedures. General procedures are inspected by inspectors, key procedures are inspected by both inspectors and technicians, and key procedures are jointly inspected by inspectors, technicians and chief engineers in charge of quality. Through standardized quality control procedures, the quality of each part produced by the company is effectively controlled from raw material procurement to smelting and pouring to processing and assembly. The one-time qualified rate of parts and complete machines is above 98%.

Foreign supervision is a secret of Jinyang mining machine to achieve counter attack. Another secret may be that Jinyang Mining Machinery is located in Hengyang City, Hunan Province, and Hengyang Metallurgical Machinery Factory, once the largest and most brilliant enterprise in Hengyang, is a subordinate enterprise of the Ministry of Metallurgy and China Nonferrous Metals Corporation. It ranks among the best in the national mining and metallurgical equipment industry, with more than 30000 employees in its heyday. Relying on Hengyang Metallurgical Machinery Factory's rich professional resources and deep mining equipment technology accumulation, Jinyang Mining Machinery has attracted a group of top talents from Hengyang Machinery Factory to join its technical research and development and management team to jointly overcome the difficulties of localization of high-end cone crushers.

For example, Mr. Wang, the general manager of the company interviewed by the reporter, and Mr. Xiao, the deputy general manager of the company, have worked in Hengyang Metallurgical Machinery Factory for decades and are first-class professionals in the industry.

Mr. Wang used to be the director of the foundry branch of Hengyang Metallurgical Machinery Factory. Foundry smelting is the core technology of mining equipment and materials manufacturing. The copper sleeve on the cone crusher of Jinyang mining machine's fist product is precisely because it has mastered the technical process of copper alloy casting. In 1986, Germany and China signed a friendly cooperation agreement to train a group of outstanding management talents for large Chinese enterprises free of charge for a period of three years. Germany is a global manufacturing power, German-made products represent the high quality, safe and reliable, technologically advanced. Mr. Wang is one of the members of this group of study classes in Germany. He studied the theoretical knowledge of business management in German universities for one and a half years, and worked as an intern in world-class companies such as Mercedes-Benz, BMW, and Demark for another year and a half. The management staff of the company contacted and worked together, and learned the practices of German companies with the problems of Chinese companies.

The three-year advanced training in Germany has broadened Mr. Wang's international vision and improved his business management level. "What we learn in Germany is a full set of large enterprise management, financial management, personnel management, on-site management, technical control and so on, all-round learning. The essence of German enterprise management is high efficiency, clear responsibility, working procedures, timing and quantitative, while in the past, Chinese enterprises were overstaffed and could do whatever they wanted, with no norms and lax implementation of standardization." After returning from his studies in Germany, Mr. Wang applied Germany's advanced enterprise management knowledge to Hengyang Metallurgical Machinery Factory. A few years ago, he was invited by Yang Jian to serve as the general manager of Jinyang Mining Machinery. He also applied the advanced management methods and experience he learned in Germany to the ground in Jinyang Mining Machinery.

Yang Jian admitted, "To be honest, since Jinyang Mining Machinery started its business, it has received the help of many engineers and technicians from Hengyang Metallurgical Machinery Factory to develop the core components of the cone crusher."

Of course, the success of the localization of the cone crusher of Jinyang Company benefits from the localization strategy that the country is committed to implementing, and benefits from the support of the localization of large state-owned backbone enterprises such as Jiangxi Copper Group. A manager of the equipment department of Jiangxi Copper, who did not want to be named, said, "Jiangxi Copper people have a strong sense of industry serving the country. They have always supported localization work, encouraged domestic equipment manufacturers to innovate independently, and gradually increased the localization rate of advanced equipment. Batches of localized high-end mineral equipment were successfully landed with the support of Jiangxi Copper."

He Labai analyzed that the success of Jinyang mining machine has two economic significance for China's high-end cone crusher. First, it breaks the long-term monopoly of foreign countries in this field of China, ensures the safety of China's mineral processing industry, and improves the voice of Chinese enterprises and the intensity of market competition; second, due to the emergence of competition, the price of imported similar equipment has been greatly reduced, It reduces the equipment procurement expenditure for Chinese users. "Jinyang Mining Machinery is a small-scale private enterprise, but it has grown into a high-quality supplier of the world's top 500 companies and an invisible champion in the field of high-end mining machinery."

Today, the complete machines and accessories of Jinyang Mining Machinery have successively entered the procurement lists of China Metallurgical Science and Industry Group, China Nonferrous Mining Group, China National Gold Group, Baotou Steel Group, Zhongjin Lingnan, etc., and have become the-level of many large non-ferrous metal and ferrous metal mining companies. supplier. Crusher industry rookie Jinyang mining machine, has attracted the attention of strategic investors, hope to invest in shares to do large-scale. Although it is only a small and medium-sized enterprise, Jinyang mining machine has long-term ambition. At this critical stage of development, the Beijing Boyang Zero Inquiry Management Consulting Team is introduced to make future strategic plans for Jinyang Mining Machinery, help establish a modern enterprise management system, and introduce strategic investors for the next step to carry out the company's shareholding system transformation. To land in the capital market in 5 years.

"turn iron into gold, and I will do my best." Jinyang mining machine is comparable to the global mine high-end crusher manufacturers, winning the battle of localization of high-end crusher. Yangwei mining industry is undoubtedly an excellent evolutionary sample for the transformation and upgrading of Chinese manufacturing and moving towards high-end.
