The existing impact crusher is mainly of a closed structure. The closed runner adopts a mode of combining the hard alloy blade and the machine body material thereof for blade installation, and residual stress is inevitable due to the difference of thermal expansion of the hard alloy blade and the machine body material. In addition to the impact forces caused by the rock impacts, the carbide inserts can be damaged. Moreover, the carbide blade is a brittle material, so that the carbide blade is easy to crack based on the working condition of the carbide blade.

In another aspect, the utility model discloses an impact crusher, the runner of which is the runner of any one of the above
The utility model has the following beneficial effects:
1. the material falls from the feeding hopper of the impact crusher and enters the rotating wheel; because the straight line AO and the straight line that the collision surface projection is in form the included angle alpha, namely the collision surface of the cutting board is opposite to stone material brought out by the centrifugal force that the runner plate rotates, namely the runner throws away the material through the high-speed rotation, and hit on the collision surface of the cutting board, make the stone material break; through the included angle alpha, the crushing effect is ensured, and meanwhile, the abrasion of the cutting board is reduced; meanwhile, the impact block carries out impact crushing on the stone positioned at the periphery of the rotating wheel again, so that the stone is crushed more thoroughly, the crushing effect is improved, and the stone crushing efficiency is improved;
2. the thickness of the knife plate is gradually increased along with the distance from the point A, namely, the farther the stone thrown out by the rotating wheel is, the larger the impact force of the stone is, the larger the thickness corresponding to the part of the stone which is impacted on the knife plate is, so that the impact force of the stone is resisted based on the thickness of the knife plate, the strength of the knife plate is improved, the service life of the knife plate is prolonged, and the maintenance frequency is reduced;
3. the materials fall from the feed hopper of the impact crusher, enter the rotating wheel, are stacked on the material distribution cone and are guided to the periphery through the conical surface of the material distribution cone, so that the materials flow to the peripheral impact units as uniformly as possible and are thrown out by the centrifugal force of the rotating wheel, and the crushing uniformity of stone materials is improved;
4. the flow field plate employs a highly wear resistant surface, such as a chrome plated surface. When the rotating wheel works, when the stone at the bottom is thrown out by the rotating wheel, the stone slides to the knife board along the surface of the runner plate to be impacted, and cannot be directly contacted with the rotating wheel disc, so that the service life of the rotating wheel disc is prolonged; meanwhile, the wear resistance of the runner plate is high, and meanwhile, the wear resistance of the runner plate is only required to be improved, so that the manufacturing cost of the whole equipment is effectively controlled.
