国外在20世纪80年代,成功推出了物料自冲击的立轴式破碎机,广泛应用于金属和非金属矿石、建筑材料、人工造砂及各种冶金矿渣的破碎与整形。国内从1992年开始就有企业对立轴冲击式破碎机进行研制,由于受零件材料及加工精度等方面的限制,该设备的破碎效率和处理能力一直未能取得突破。笔者在不改变叶轮直径、转速、设备功率等参数的前提下,通过对传统立轴冲击式破碎机叶轮结构的 Foreign in the 1980s, the successful launch of self-impact material vertical shaft crusher, widely used in metal and non-metallic ores, building materials, artificial sand and a variety of metallurgical slag crushing and shaping. Since 1992, domestic enterprises have developed a counter-shaft impact crusher, due to the limitations of parts and materials and processing accuracy, the crushing efficiency and processing capacity of the equipment has been unable to achieve a breakthrough. I do not change the impeller diameter, speed, power equipment and other parameters under the premise of the vertical shaft impact crusher impeller structure
