The development of scrap crusher is related to many industries, such as steel industry, mining industry, construction industry and so on. The development of scrap crusher has a history. After a long period of practice, metal crusher, metal shredder, vertical crusher have appeared. The machinery industry is still in a low period in the 1980s, the economic development is in a relatively stable state at that time, just in time for the smooth development of the Chinese economy, each industry has a periodic development, the mechanical industry is generally a cycle of more than ten years, the order followed is from the early stage of industry development to the peak period, and gradually to the low period of the machinery industry. This cycle of development has never changed, and it cannot be changed. Because every industry has its cycle of development.

     The development of scrap crusher industry is closely related to the economic chain. China's economic construction has gradually developed with a rapid momentum since the early 1980s, no matter which industry, including railway construction, highway construction, as well as real estate development, mining, water conservancy industry and other industries are developing rapidly, and the development of these industries has formed an economic industrial chain, for example, cement, stone, sand and so on are used to build highways, which ushered in mines. The peak period of the rapid development of sand and stone industry, and the production of mine sand and stone should use crushing equipment, so the development of mining equipment crushing machinery industry has gradually entered the peak period. For example, there are more and more used metals, and with the rise of machinery industry and other building materials industry, there is a shortage of iron and steel resources in our country, which requires scrap crusher to resmelt all kinds of waste metals and re-forge them into other steel products. Only in this way can we alleviate the shortage of resources in our country, make metal resources continue to continue, and the development of this industry accelerates the development of the steel industry. On the surface of the above examples, the development of each industry is closely related to the industrial chain.

     The crusher eats and transfers every industry, cheap supplies and high profits, enough to call it the ten thousand gold oil industry.
