1·The materials are accelerated by the rotor into a certain absolute speed and direction, and impact on the striking board in a positive bumpiness status with the materials crushed effectively.
物料经转子加速后以一定的绝对速度大小和方向冲击在打击板上，物料与打击板处于正碰撞状态，使物料得以有效破碎。
1·The utility model has the advantages of increasing the elasticity of the tire, improving the travel performance of the tire, and reducing the bumpiness of vehicle.
本实用新型有增加轮胎弹性，改善轮胎行驶性能，降低车辆颠簸的优点。
