　　Impact Crusher(New Type Impact Crusher)：An impact  crusher  is a stone crushing machinery using impact energy to crush  stones . When the impact crusher is working, the rotor driven by the electromotor rotates at a high speed, and the  stones enter  the functioning area of   blow bars  and impact the blow bars mounted on the rotor  and are crushed , and  then thrown onto the impact liners to be crushed again by impact,  and rebounded into the functioning area of  blow bars to be crushed  once more by impact. Such a  process will be repeated for stones to enter the 1st, 2nd and 3rd crushing cavity based on the size range from big to small until the crushed stones are  small enough to escape from the bottom discharging port .  It is possible to change the discharge sizes by adjusting the space between the impact rack and the rotor , or by adjusting the rotating speed of the rotor .
　　The crushed stone product  produced by impact crusher  is of a similarly cubic shape  , free of tension and free of fissures, meeting the requirement of high quality stipulated by expressway , high-speed  rail and cement mixing station  and so on. It is suitable for crushing  stones with  less than medium hardness and with feeding sizes of no more than 300 mm and discharging  sizes of  no more than 50 mm(however, the specific feeding and discharging sizes  should be decided by the  stone hardness and by choosing crusher models .).
　　Our company has optimized the technical parameters of impact crusher . Blow bars on the rotor are assembled with clamping block  devices , easy to be installed  and dismantled ,and safe and reliable to operate. The impact angles are designed scientifically , increasing the impact force . Repeated impact between stones and blow bars , between stones and impact  liners, and rock-on-rock will occur for many times when the stones move down in the crushing cavity, leading to higher crushing rate and higher finished product output, and less abrasion cost . Impact liners are added on the base of the two-chamber type impact crusher for forming the third crushing cavity and increasing impact times . The side door is enlarged,  and it becomes more convenient to replace blow bars and impact liners, or to make examinations  and carry out maintenance inside the  machine  chamber.
　　New Type Impact Crusher : The main shaft  is made of 40Cr steel instead. Dedicated  quality bearings of European  brand are used instead ; an equilibrium feeder is added,  allowing  stones to distribute uniformly in the crushing cavity and improving the utilization of  impacting space inside the crushing cavity. Z type blow bars are adopted for higher utilization  rate  of  blow bars. Movable  square steel is adopted . When  the gap between the blow bar and square steel becomes too big because of  blow  bar  abrasion , the square steel may be moved to avoid too big gap and  stone leakage  , ensuring all stones crushed by impact and the quality of finished  gravels. The new type impact crusher has been awarded national patent .
