Impact crusher is a kind of crushing equipment which using impact energy to crush materials .It can crush material with crushing compression strength not more than 360 Mpa ,and particle size not more than 500mm . Finished product with cubical shape and has features of big crushing ratio, high crushing efficiency, convenient maintenance, etc. Impact crusher is the ideal equipment for highway road surface and hydropower construction aggregates processing .

At the moment,Zhengzhou Yifan Machinery Co.,mainly manufacture impact crusher with two big series ,one is HCP series ,another is PF series .And HCP hydraulic impact crusher is the result of constant structure improvement and technology upgrading based on PF series .High wear-resisting material and best crushing cavity endow HCP crusher with superior performance .Its working principle is as follows : When the materials enter the hammer plate zone, will soon be crushed by the high speed impact hammer. and then be thrown to counter device installed at the top of the rotor for crushing once again , and then rebound to hammer plate zone from the plate liner crushing again . Repeat this process over and over again until the material is crushed to the desired granularity and released by the lower part of the machine . You can adjust the clearance between the back frame and rotor frame to achieve the purpose of changing the particle size and shapes . Besides,there is a spring safety device behinds the impact plate to prevent non-crushing material going into the crushing cavity.
