The impact breaking machine series is optimized after adopting domestic and foreign technique. It can process granite, basalt, limestone, etc, which the granularity is not bigger than 120-300 mm and crushing compression strength is not more than 320mp.It features high crushing scale, and high crushing efficiency and it is convenient for maintenance. This cube-shaped fineness product is the first-class device used in high grade road surface, railway, and water conservancy and electricity industry.
Crusher’s development history can be traced back to the 1850s, when the world’s first jaw crusher was born in the United States, and soon after with the development of productive forces, jaw crusher has been broken can not meet the technology needs, so based on jaw crusher, people had designed the impact crusher.
PF series impact breaking machine is applicable for crushing the semi-hard materials and has big throughput and small granularity of materials. This series of crushers can process the material with the side length of 100 to 500mm and the compression strength can reach 350mp and have the advantages of big reduction ratio and cubic shape after the crushing of materials.
More well-known impact crusher of the abroad company, Japan’s Kawasaki Heavy Industries, the German company of HKD, Spain Rover firms and so on. But impact crusher relatively late development in China, to the 1950s, China has really broken machine. Thus, China’s crushing and screening equipment, mostly 50’s came out. In the 1980s, we made impact crusher is limited to processing the hard materials of coal and limestone. Until the late 1980s China has introduced KHD-type hard rock impact breaker, it filled a gap-free of high hardness crusher. But the technology was behind twenty years to abroad.
How it is operated: It is a kind of crushing equipment, using impact energy to crush materials. When materials get into the area where the board hammer plays a part, under the impact function of board hammer at a high speed, the crushed ones are thrown to the impact device above the rotor continuously. And then they are rebounded from the impact liner to the area where the board hammer plays a part, and are impacted again. The materials from large ones to small ones get into the impact cavity for being crushed repeatedly. The process is going on until the materials are crushed to the required sizes and discharged from down of the machine.
Overall, the main performances of home and abroad impact crusher in the future development are:
First: research and develop the high toughness, high wear-resistant materials to improve the new plate hammer’s life and improve productivity.
Second: In order to meet market and customer needs, this series of crushing equipment has to be standardized, large-scale development.
Third: insist on technology innovation, and gradually get rid of the product of a single introduction and imitation.
