Powder is an aggregate of many small particles. The common feature is that it has many discontinuous faces, a large specific surface area, and is composed of a large amount of small particulate matter. The author understands that the composition of the powder should satisfy three conditions. The microscopic basic unit is a small solid particle; macroscopically, it is a collection of a large number of particles; there must be interaction between the particles. With the advancement of pharmaceutical production and the combination of crushing technology and pharmaceutical engineering, powder production equipment has gradually been adopted by pharmaceutical companies.

The author has learned that after decades of development, China's powder equipment manufacturing industry has entered the stage of self-development from introduction, imitation and manufacturing, and has made new progress. This progress is mainly reflected in the innovation of equipment structure, off-season processing capacity, wear resistance, process matching, automatic control and improvement of energy consumption per unit product. In addition, as the pace of development in the processing industry and the pharmaceutical industry accelerates, the upside of powder equipment will further increase.

However, similar to the development of other sub-areas in the pharmaceutical machinery industry, there are still some problems in the powder equipment industry that need to be resolved. First, China's research on powder technology is late in the world's advanced countries, and equipment development is also late. In the case of weak foundation and low starting point, most pharmaceutical companies chose imitation, but the quality is inevitably uneven.

According to industry insiders, although after a long period of development, China's powder equipment industry has made certain progress, but low-level competition and repeated production still exist. “Enterprises name themselves and name their own device code, which leads to some manufacturers’ equipment, instruction manuals and even advertisements. Not only does the layman not understand, but the insider does not understand.”

Second, there are not many types of powder equipment. Some varieties in the industry lack innovation ability, many utility model patents, and fewer invention patents; more improved models and fewer original models. It is reported that compared with the foreign technical level, there are still large gaps in the preparation and classification of ultra-fine powders and grades, especially in the automatic control of electromechanical integration. In addition, in terms of materials and processes of manufacturing equipment, China's powder equipment also has a long way to go.

Third, although the number of enterprises is large, the scale is small and the competitiveness is insufficient. The author understands that at present, the development of China's pharmaceutical machinery industry is accelerating, pharmaceutical companies are all over the country, but the scale is still small, and the powder equipment industry is also the same. Throughout the powder equipment industry, except for a few large-scale enterprises, most of them are small-scale enterprises.

According to industry insiders, small enterprises cannot fully control their production quality and product technology, and their advantages cannot be fully exerted. At the same time, these companies often seek a piece of market in the market through price wars. However, this method does not bring long-term benefits. Instead, it will result in low economic returns and development of enterprises and even industries. .

Fourth, geographical development is uneven and professional talents are relatively scarce. According to relevant experts, powder equipment, technical production and research units, especially production enterprises, are mainly concentrated in the Yangtze River Delta and the Pearl River Delta. Other regions are not sensitive enough to stimulate the field. In addition, talent is also a big problem. The pharmaceutical machinery industry is a technology-complex industry. It requires talents who know both powder knowledge and mechanical manufacturing and computer technology. However, according to the current development of the industry, professional talents still have a large gap.

Fifth, the industry standards are lacking and have not been unified. It is reported that powder equipment has a history of development in China for decades. However, at present, there are no series of powder equipment industry standards and national standards in China, and there are only some sporadic standards related to powder equipment. Not only that, the enterprise standards for powder equipment have not been unified. The relevant enterprises indicated that there are mechanical standards for their peers and foreign standards for their counterparts. There is no consensus on standardization, which has also caused the domestic powder equipment industry. The phenomenon of disorderly competition.

It can be seen that although the background is good, it is undeniable that there are still some problems in the powder equipment industry in China that need to be resolved. As far as enterprises are concerned, they should get rid of the hat of low-price competition, do practical production, diligently engage in research and development, and make real achievements to play a role in boosting the industry. As far as the industry and the country are concerned, the formulation of standards should be promoted as soon as possible to help the powder equipment industry develop in an orderly manner and allow enterprises to have a clear basis for production. Only with the cooperation of all parties, the development of the powder equipment industry can be improved by the general trend of the pharmaceutical industry.
