Five kinds of commonly used in crushing machine, crusher and hammer crusher with impact the main role belongs to brittle material to break the machine, it is often called the impact crusher. Impact crusher and based compression crusher, such as jaw crusher, cone crusher and roll crusher is compared, have the following characteristics:
Big crushing ratio. Impact crusher of crushing ratio can reach above 50, and jaw crusher, cone crusher, roller crusher is difficult to more than 20. So, in need of single segment broken situations, such as cement industry, limestone jaw and cone crusher in kenya, impact crusher is widely used.
Good product particles. Under impact, often by crushing the material level of fragmentation along its most vulnerable, the selective crushing method, the particles with higher probability of a cube shape, so the percentage flakiness content impact crusher product can be less than 10%, while the percentage flakiness content of jaw crusher, cone crusher machine and roller type crushing machine products will be higher than 15%. So, in need of occasion. For example, the high grade highway antiskid pavement, impact crusher is usually used as the final breaking equipment, the production of concrete aggregate.
The above characteristics, impact crusher occupies an important position in many of the crushing machinery.
However, due to the impact crusher is used to crush materials impact principle, the blow pieces, such as: hammer, plate hammer, impact plate, wear away during use very quickly. This defect, in a quite long period of time, limit the scope of the impact rock crushers in kenya for sale. Can only be used for crushing of hard materials. At the beginning of the fifty's, with the application of new wear-resistant material, the German KHD company launched the first hard rock crusher, breaking the limitation, an improved version of this model is still in production.
Our country in the late fifty's existing crusher come out, before eighty time, homebred impact breaker limits to the processing of coal and limestone, in hard material. Until the late eighty's Shanghai construction machine manufacturer introducing KHD type hard rock crusher, to fill the domestic blank. But still behind abroad for more than 20 years. Two kinds of cost of a new stone crusher in kenya shape design, rotor structure in the cavity, especially the plate hammer material and mounting method is fundamentally different.
Homebred hard rock crusher, beginning its core parts plate hammer dependence on imports, domestic plate hammer in "eight five" period as ministerial level scientific research projects, the success of the project, the domestic plate hammer not only replace imported, and has been exported to Europe and the United States, Japan and other countries. Wear resistant materials breakthrough, make hard rock crusher mora, only Shanghai heavy machinery limited company (hereinafter referred to as the Shanghai heavy industry) as an example of the company's products have been in Southeast Asia, Europe, Africa, Hongkong, Taiwan and other countries and according to statistics, in the various provinces and cities nationwide in the highway construction have been using hard rock impact crusher machine as the pavement stone preparation equipment, to the crushing compressive strength reaches 300Mpa basalt, andesite and other hard materials, and reach the graded stone below 19.6mm. The percentage flakiness content is less than 10%. Currently has more than 400 sets in around the use, not only solved a problem in expressway construction, but also blocked the import, as hard rock impact leading manufacturing enterprises crusher, Shanghai Heavy Machinery Co., Ltd has also been developed from.
