Vibrating screening machine is a new type of machine that has been rapidly developed in the past 20 years. The vibrating screen has the characteristics of stable and reliable, low consumption, low noise, long life, stable vibration shape and high screening efficiency. It is suitable for quarrying sand in quarry. Stone materials can also be used for product classification in coal preparation, mineral processing , building materials, electric power and chemical industries. The application fields are very extensive. The current bottleneck in the vibrating screen manufacturing market China's vibrating screen manufacturing industry started late. In 1966, it only bid farewell to the imitation stage, and independently developed a number of new screening equipment with excellent performance. Although there are still many problems such as more failures and shorter lifespans, they can basically meet the needs of the domestic market at that time. In the 1980s, during the period of reform and opening up, China's vibrating screen industry began to enter a period of rapid development. China has successfully developed a series of vibrating probability screens and rotating probability screens, and completed a series of thick sieves such as box exciters, self-synchronizing heavy-duty, etc. Thick sieve series, heavy-duty hot and cold mineral sieve series, self-straining sieve, spiral three-stage sieve, and the development of powder linear vibrating screen, string vibrating screen, swirl vibrating screen and vertical cylinder screen have also achieved certain success. . At present, according to incomplete statistics, there are more than 100 vibrating screen manufacturers in Zhengzhou, Henan Province, which are gradually becoming one of the pillar industries of Zhengzhou. In addition, the machinery manufacturing of Henan Xinxiang Economic Development Zone is also very developed. The industry is one of the characteristic industries identified by Henan Province. It is one of the eight major equipment industry clusters in Henan Province and one of the seven industrial clusters in Xinxiang City. Xinxiang's vibration machinery industry's market share, product production and research and development capabilities have a very important position in the country, accounting for a quarter of the country's total output. Through years of development, China's vibrating screen has been improved and improved in structure, technology and technology. However, such a mechanical industry with excellent performance and wide application has been slow to develop in recent years, sales volume is not going up, and profit margin is getting smaller and smaller. 85% of the manufacturers believe that the demand for vibrating screens is approaching saturation. However, some companies have not realized that the problem of the vibrating screen industry itself is the key. China's vibrating screen industry has many problems With China's entry into the WTO, competition in the domestic and international markets has become increasingly fierce, and problems in product quality and development capabilities have seriously hampered the development of industry enterprises, and product technology has progressed slowly. Faced with the competitive pressures in domestic and international markets, China's vibrating screen industry still has problems such as low profitability and insufficient capacity for independent development after industrial integration. What is more serious is that enterprises do not have enough capital accumulation to solve some problems. Key issues such as preform technology and large-scale production, development of new vibrating screen products. These restrict the development of the entire industry, making the development of the vibrating screen industry a bottleneck, and at the same time leading to the emergence of vicious competition. 1. Due to the small investment in the vibrating screen industry, the profit return is high, the industry threshold is not high, some companies with weak economic strength, backward management mode and low production technology are flocking, and the vibrating screen production enterprises are uneven. With the increasing number of vibrating screen manufacturers, the competition is becoming more and more fierce, and the profit margin is getting smaller and smaller. 2. The innovation of vibrating screen technology is insufficient. Due to the backward equipment, the function can not meet the needs of customers, and the customer turns to purchase Other equipment, and the market development momentum is insufficient. 3. The domestic vibrating screen market, especially the production technology of the vibrating screen series products, still stays at the level of the 1990s. Some producers still focus on counterfeiting, and the market homogenization competition is serious. Since the product is the foundation of the company's survival, here we focus on the problems that the vibrating screen enterprises have in the development of new products. China's vibrating screen enterprises pay less attention to the development of new products. The main performances are as follows: First, the investment in research and development of new products is insufficient, the development capability of enterprises is weak, and the proportion of research and development expenses to sales is too low. The actual investment of general enterprises is only about 1%, while the large enterprises in industrialized countries are more than 5%, and some are as high as 10%/. Second, the technical staff engaged in research and development work is insufficient. Our enterprise developers account for only about 1% of the total number of employees, while the developed countries are mostly above 10%. Third, the enterprise development institutions are not perfect. Although there are some technology development institutions in the screening equipment manufacturing enterprises, there are not many development institutions with certain level and strength, which is quite different from foreign countries. Fourth, the enterprise's ability to use scientific research and development of the society is insufficient, social development is out of line with enterprise production, and the rate of commercialization of scientific research results is low. All of the above factors have caused the profit margin of vibrating screen production enterprises to become smaller and smaller, and there is not enough funds for technological innovation and research and development of new products, forming a vicious circle. Internal and external repairs to promote the transformation of the vibrating screen industry Our vibrating screen production enterprises, especially state-owned enterprises, have the primary problem to solve. First, we should adapt to market demand and participate in market competition as soon as possible in the system. Second, solve product technology problems. 1. Accelerate institutional reform We should realize that the competition in the international market is not only the science and technology, the quality, but also the competition of efficiency and system. The status quo of screening machinery products has remained unchanged for decades, which has seriously hindered the efficient participation of enterprises in the market competition. Therefore, enterprises should establish an advanced management system, improve the level of equipment, accelerate the process of enterprise information, and enable enterprises to participate in the conditions of competition. In the industry, for the areas where the vibrating screen manufacturers are concentrated, industry associations should be introduced. On the one hand, it is easy to manage and constrain the behavior of enterprises. On the other hand, resources can be shared and promoted to form industrial clusters and strengthen industrial strength. Taking Henan Xinxiang as an example, Xinxiang Vibration Machinery Equipment Industry Association was established in September 2007. Now there are 94 member units. The association has played an important role in strengthening industry management, coordinating corporate relations, strengthening technical cooperation, and promoting industry self-discipline. Further promoted the standardized and orderly development of the vibration machinery and equipment industry in Xinxiang Economic Development Zone. 2. Increase technological innovation and new product development efforts Products that do not adapt to the market will be eliminated by the market, but it is necessary to know that there is no product that will always adapt to the market. The wide range of vibrating screens can offset some of the negative factors in the market competition. Therefore, understanding the market and actively improving product technology are the basis for the survival of modern enterprises. At present, the level of equipment and backward technology are important factors affecting the development of our screening equipment manufacturing industry. Enterprises can not blindly "close the door to build a car", listen to the needs of the market and customers, purposefully and targeted product upgrades, technological innovations and new product development, such as material innovation, vibration mode changes and so on. Only in this way can the products produced be recognized by the market. Further, on the basis of adapting the product to the market demand, it is also necessary to have characteristics. Without special features, it will not be able to form pillar products in this field, and enterprises will have no place in the market competition. To achieve "people without me, people with me excellent, people with my new", the introduction of funds, absorb talents, produce distinctive pillar products, enterprises can develop healthily. In addition, product technology should be reasonably positioned. Different application fields may have different performance requirements for vibrating screens. Enterprises should correctly understand their own advantages, rationally locate them, and become more and more broad in their own areas of advantage to avoid homogenization competition. 3. Talent is the core driving force of technological innovation Enterprises can't do without the support of capital and technology. They should use the national industrial development policy, strengthen cooperation between enterprises and enterprises, universities and research institutes, strengthen their own strength, provide support for technological innovation, and promote major technologies. Industrialization of results. We will improve the technological innovation system that combines enterprises as the mainstay, market-oriented, and production, education and research. Enterprises with conditions should also establish a science and technology research and development center to cultivate their own scientific and technological innovation talents. 4. Recognize the development trend and promote energy saving and emission reduction in the industry Under the environment of expanding domestic demand, promoting growth and optimizing structure, industrial upgrading and ecological environmental protection construction, the vibrating screen equipment manufacturing enterprises themselves and the energy conservation and emission reduction of products are also the inevitable trend of industry development. The development of industry has become more and more demanding on the variety and quality of vibrating screens. The development of vibrating screens has also been upgraded to a new stage. In the future, the vibrating screen industry will develop to high-efficiency, high-yield, standardization and structural environmental protection. The product technology and processing capabilities put forward more stringent requirements.
