The relationship between the yield of crushed product and the operating parameters was established. The crushing mechanism was analyzed and the effects of hammerhead style, rotation speed, and inlet water volume on particle size distribution were investigated. The results show that the highest yield of 1 + 0.75 mm sized product was obtained with an inlet water volume flow rate of 5.97 m 3 /h and a smooth hammerhead turning at 1246.15 r/min. Cumulative undersize-product yield curves were fitted to a nonlinear function: the fitting correlation coefficient was greater than 0.998. These research results provide a theoretical basis for the highly effective wet crushing of PCB's. 关键词：印刷电路板尺寸分布湿粉碎冲击式破碎机产品产量函数拟合介质击穿运行参数
