Abstract The performance evaluation of the cutter can be carried out according to the national standards, but the measurement of capture efficiency using 8 kinds of monodisperse particles with particle sizes is time-consuming and the process is complicated. To solve the aboved problem, the influence of mixed particle size on the evaluation of the cutter was studied. By mixing and atomizing the monodisperse particles with different particle sizes, the efficiency of the cutter under several particle sizes could be obtained at one time. By applying the mentioned method and the traditional method to the evaluation of domestic and imported cutters, and comparing the evaluation results, it can be seen that Da50 and the geometric standard deviation δg have good consistency, with the deviation not exceeding 3%, and the measurement time of the mentioned method is 80% shorter than that of the traditional method. The results of the study provide a reference for optimizing the evaluation process of cutter.
