Problems and development suggestions for superfine crushing equipment industry in China

1 Introduction
In recent years, due to the demand for large-scale economic construction and development in China, China's crusher industry has made great progress, especially in the high-speed development of coal, cement, metallurgy, nonferrous metals, non-metallic minerals and other industries, and the demand for crushing machinery has also risen. The total amount is constantly increasing. The National Twelfth Five-Year Development Plan has clearly pointed out that it is necessary to speed up structural adjustment, transform economic growth mode, and achieve the goals of saving, reducing consumption, and reducing emissions. Under this premise, China's crusher (superfine crusher and super-segmentation machine) The industry has put forward higher requirements. In this case, the author of the paper puts forward the following points according to the decades of work practice in this industry, and discusses with the teachers and students of relevant enterprise leaders, research institutes and universities in the industry.

2 Development status of China's superfine pulverizer and super-segmentation machine
The author has clearly stated in the articles published many times before. Generally speaking, since the 1970s, due to the development of world technology and the demand of non-metallic minerals, metal mines, and powder metallurgy in China, China has promoted China. The ultra-fine pulverizer industry has developed rapidly. Through the introduction, digestion and absorption of advanced equipment from developed countries, it has spawned the development of superfine pulverizing equipment in China. Looking at China's superfine pulverizer market, the whole series of equipments such as mixing mill, jet mill, ring roller mill, etc. are all produced, which basically meets the demand of small-scale superfine pulverizers in China.

However, the development of the larger super-segmentation machines required for ultra-fine powders, but one step behind them, cannot fully meet the needs. After nearly 30 years of development and change, the relatively stable superfine pulverizer manufacturers are mostly satisfied with the relative market share of the equipment they produce, so most of them are busy with production, and they are not considering the future market demand and enterprise development. Many, even if some people think about it, there are no ways to be constrained by technical support, development, and capital. You can only take a step and wait for the market to push yourself forward.

3 hinder the problems in the development of ultra-fine pulverizer (classifier) ​​industry
The development of China's superfine pulverizer (classifier) ​​industry is relatively slow, which can be summarized in several aspects. It is described as follows:

3.1 The industry started relatively late
Superfine pulverizer (classifier) ​​This industry has been introduced since the 1970s. Until the mid-1990s, China's equipment manufacturers were basically in a relatively stable state. Compared with advanced countries, we were 20- late. In the past 30 years, China’s research in this area has only begun at this time, so starting late is a feature of ours. Starting late, the level of equipment manufacturing is relatively low, which is an issue that cannot be avoided.

3.2 The scale of the company is small, the development layout is uneven, and there is no large equipment.
China's ultra-fine pulverizing equipment factory, at present, the relative size of the manufacturers of production-specific equipment is very small, can not produce large-scale equipment, according to the production of 1250 mesh as the standard, the production of Taiwan production time is almost no more than 500T , so the equipment has an annual output exceeding In large-scale production plants with a fine powder of more than 5 million tons, almost no equipment is available. Of course, the crusher produced by the small powder processing plant is full of varieties, but the small factory can not accept the "high, fine, sharp" requirements of the large enterprises.

Secondly, due to the limitations of China's national conditions, the crushing machinery production plants are mostly in the Yangtze River Delta and Pearl River Delta regions, and there are few such plants in the northeast and northwest. This creates an imbalance in the industry and is detrimental to technological development. The existing workshop-type equipment processing factory, although the appearance of the equipment is very beautiful, but the lack of technical content, the design is not regular, the processing technology is not accurate enough, the equipment material selection is wrong (this problem is discussed later), the result The technical content of the equipment cannot be guaranteed. Due to the small scale of the enterprise, the capital chain is often unable to guarantee, resulting in production difficulties and inability to participate in market competition. As a result, the company's efficiency is not good, making the development of the entire industry unrelenting, and it is impossible to talk about technology development and market expansion.

3.3 too little scientific research, lack of technical support
China's superfine crushing equipment manufacturers, many of which are small production plants, lack of technical strength, no technical reserves for production and development, even if some enterprises have some understanding, and scientific research, universities and other units jointly develop new products, but according to the author, At present, the domestic research on crushing machinery cannot keep up with the development of the situation. After many former colleges and universities have been converted into comprehensive universities, few of them have been set up in this field. It is rare to cultivate talents in this field. Some professors and experts are not mechanically designed. It is very good to work hard on the theory, often just taking students to study some parameters of a certain kind of equipment.

3.4 too little independent research and development
Without theoretical development, it is often copying and counterfeiting. It is a great improvement. In patent applications, most of them are utility models, rather than independent inventions. This is one of the main problems that equipment can't improve.

The root cause of the above problems is that the investment in research and development funds is too small. The state has not taken this problem as a big problem, and there is no more funds available under it. Therefore, it is necessary to call for the development of superfine crushing equipment in terms of technology funds related to this. There is sufficient funding to train talents, to study theory, and to further guide equipment manufacturing.

3.5 No industry standard, equal to disorderly production
Superfine pulverizers (classifiers) have many production enterprises in China, but so far, the country does not have uniform equipment standards, and some units try to lead the industry standards, but because the lead units are not authoritative, few responders. No national standard has been introduced to date.
It is more difficult to engage in industry standards first, and the units that initiated the project are underestimating the difficulties. Because this is a national unity, it must have sufficient authority, and it has no authority and no appeal. Second, it is necessary to invest in standards, and it costs money. This cost is not a source. This is a big problem. Third, there must be a group of experts and entrepreneurs who have both theory and practice to discuss it. And then get the practice to verify, so that the standard can be convinced, everyone will recognize the account, fourth, after the national standard comes out, everyone must abide by, this is important. In short, it is a matter of public opinion to engage in national standards. Whoever takes the lead is indeed a problem. The leader without funds is unable to get it, because now is the era of market economy. Without financial support, it is equal to not saying.

3.6 Lack of independent innovation products
In recent years, the patents and process methods of the national intellectual property rights application are still relatively small, and many patents are still in the "improvement" stage of the utility model, and there are very few patents that are truly patented.

After the patent application, it will take some time to implement it. After some patent applications, it will not be implemented, so there are fewer new products seen in reality.

3.7 Bad competition is a big regret for China's superfine crusher market
Nowadays, after the market is generally a good device, the equipment has good production effect and good economic benefits. Even if you apply for a patent, some people will copy this product and will soon appear on the market. Some people say that they can sue the infringement of the system. In fact, this kind of lawsuit cannot be won. The reason is "who advocates and who gives evidence." The claimant needs to spend a lot of money and manpower in obtaining evidence, and finally pays no money. Therefore, many people Abandoned this lawsuit. This is a disadvantage to patent protection in Chinese law, so it makes the counterfeiters bold. Some people use it for counterfeiting.

4 future development
In summary, the author believes that the future development direction of China's ultra-fine crushing machinery (super-segmentation machine) is based on the current domestic and international market needs, and should vigorously expand the market, especially in overseas markets.

4.1 Seeking new principles, designing new models, new models
China's equipment manufacturing industry has been paying attention to the European and American markets in recent years. We have already made the banner of Chinese manufacturing. Now it is time to turn China into China and become China. Therefore, according to the current market demand, the deep processing of mining materials is becoming more and more important. In the national 12th five-year development plan, many new materials are inseparable from ultra-fine powder materials. With the refinement of market demand, different application fields In the powder particle size, particle size distribution, particle shape, specific surface area, pore volume and the like have different requirements, it is very important to manufacture a high-precision ultra-fine grinding machine (grading machine). This is one of the direction of corporate struggle.

4.2 Develop a higher-grade superfine pulverizer
A long time ago, some experts in China proposed to research and manufacture nano-scale pulverizers. However, due to the lack of objective environment, this work was only verbally proposed but almost no progress. At present, China’s mechanical processing digitalization has made great progress, and different levels are different. Metallic materials have been mass-produced, which has created many conditions for the manufacture of precision pulverizers. People of insight should make great efforts in this regard. Strive to produce nano-scale crushers as soon as possible.

4.3 The large-scale equipment is forced to
The lack of large, efficient pulverizers in the domestic market is the status quo. Many industrial enterprises have to expand production or build new mines, and they have to build large factories. Because they cannot find high-efficiency and energy-saving large-scale superfine pulverizers, they have a hard time to produce large-scale superfine pulverization with a daily processing capacity of 1,250 mesh. Machine should be a common understanding. Large super-segmentation machines that are compatible with them should also be developed. According to reliable information, some domestic equipment factories have begun to work hard in this regard.

4.4 Device digitization
The development of large-scale equipment requires higher digitization. It is necessary to study the extreme digitization of ultra-fine pulverizers and ultra-fine-segment machines. It's hard to imagine what a large machine would look like without digital control.

4.5 Further update and study of multi-force field combination models
Achieve high-tech content, high quality and high added value of pulverizer powder products.
4.6 Multi-variety, multi-model and energy-saving equipment.

5 The further development of the crusher enterprise should recognize several problems
This problem is a problem that must be faced in the face of crusher manufacturers for many years.
5.1 must have its own wear-resistant material factory
All kinds of pulverizers require different metal wear-resistant materials in various parts of the interior. Some medium and small-sized equipment manufacturing enterprises and metal wear-resistant parts must be processed by external committees, which often fail to meet the requirements of equipment design. When the device is used in the hands of the user, it causes a lot of trouble, and thus the crusher does not achieve the design effect.
The company has its own metal casting processing factory. According to the requirements of the subscribers for the equipment, the company can change the varieties of the wear-resistant materials at any time to meet the requirements of the users for the crusher products. Therefore, a good crusher manufacturer must recognize this. A little, and work hard to achieve.

5.2 Have their own corporate marketing experts and a good marketing team
A good company must have one or several marketing experts and a good marketing team (not a sales expert). It is necessary to grasp the market trends, find out the market's information about its products, adjust the market demand in time, and break into its products as soon as possible. To expand the share of its own business, in the business negotiations, the company does not have its own market share, this enterprise has not developed.

No matter what kind of enterprise, it is impossible to "sell" the products by itself. The use of unfair competition means, such as price competition and commodity fraud, is not a solution, and it should not be, and it is not suitable for our society.

5.3 Learn to diversify
A pulverizer equipment manufacturer should care about the original particle size of the raw materials before the pulverizer is fed. It is possible to manufacture crushers corresponding to your production machinery, such as crushing various crushers below 15 mm, prompting users to choose this. A variety of configuration equipment to achieve more than a small amount of grinding to make the equipment produced by the company more energy-efficient, reduce consumption. A variety of small particle size pulverizers are produced.

Secondly, there is a wear-resistant material factory, you can produce the jaws of the crusher, the lining of the ball mill, and the grinding ball. These kinds of things are the perennial consumables of various production mines that use the breaking and grinding process. The wear-resistant materials of various steel types have broad market prospects. According to the author's decades of experience, this is a good production branch of the company with excellent benefits.

5.4 Start a powder processing plant
The crusher manufacturer can use its own equipment to set up a powder processing plant, which uses its own equipment to make a powder demonstration production line that can be visited by users. It can also produce ultra-fine powders that are needed in society and increase the profits of enterprises.

5.5 Learn to reorganize resources and jointly manage
Business leaders should pay attention to the human resources and restructuring of production resources, learn their own cross-industry diversified operations, build group companies, strive to enter the market, make enterprises bigger and stronger, and learn to go outside to run enterprises. This is The entrepreneurial spirit of entrepreneurs.
