When the world's first jaw crusher was born in the United States, with the development of productivity over time, the jaw crusher can no longer meet the needs of crushing technology. Therefore, on the basis of the jaw crusher, people have designed a Impact Crusher.

In 1924, on the basis of summarizing the structural characteristics and working principle of the hammer crusher of the squirrel cage crusher, Andreson invented the AP series impact crusher, which is similar in structure to the modern impact crusher. Since the material needs to be impacted repeatedly, the material can be discharged freely and unimpeded during the crushing process. However, due to the limitation of the feeding force and the capacity of the impact crusher, its model is gradually transformed into a squirrel-cage crusher, which is applied to medium-hard crushers. Finely crushed. Thanks to the relatively high production efficiency of this kind of impact crusher, which can handle relatively large materials, and its relatively simple form and structure, and easy to move, this kind of impact crusher has been developed rapidly. Along with the increasingly perfect crushing and screening crushing theory and the further development of technology, various high-performance impact crushers emerge in endlessly. The foreign manufacturers of impact crushers are relatively well-known, such as Cedar, ids company in the United States (formerly Iowa Machinery Co., Ltd. Company), Sweden Svedala, Finland Nordbe Pen Company, France Dragon Company and Spain Rover Company, Germany Hazemag, KHD, Xinupp Company, Japan Kawasaki Heavy Industries and so on.

Until the end of the 1980s, my country introduced the KHD hard rock impact crusher to fill the domestic gap. But it is more than 20 years behind foreign countries. Domestically produced hard rock impact crushers relied on imports for their core parts, the blow bar, at the beginning. The domestically produced blow bar was listed as a ministerial-level scientific research project during the "Eighth Five-Year Plan" period. After the project was successful, domestically produced blow bars not only replaced imports, but also A large number of products are exported to Europe, America, Japan and other countries. The breakthrough of wear-resistant materials makes the hard rock impact crusher even more powerful. For example: In order to improve the quality of highway construction in our country, the Ministry of Communications once proposed a scientific research project for pavement concrete and stone crushing stations, which was included in the national "Eighth Five-Year Plan" research project. The trial-manufactured equipment of this project failed in use at a construction site in Northeast China. However, users switch to hard rock impact crushers to produce stones, which fully meet the requirements of concrete for highway anti-slip pavement. As a result, the reputation of hard rock impact crushers has been greatly improved. The Communications Department of Liaoning Province once regarded the possession of such equipment as a prerequisite for bidding for road construction. According to statistics, hard rock impact crushers have been used as pavement stone preparation equipment in road construction in various provinces and cities across the country to crush hard materials such as basalt and andesite with a compressive strength of 300MPa, and achieve a gradation below 19.6mm. stone. Its needle flake percentage content is less than 10%. At present, there are more than 400 units in use in various places, which not only solves a difficult problem in the construction of expressways, but also blocks the entrance.
