摘要：以原盐为被粉碎研究对象,通过对高压水射流粉碎原盐形貌的观察和成分分析、高压水射流原盐粉碎性能分析,以及高压水射流粉碎原盐各影响因素的正交分析,研究表明高压水射流粉碎技术对原盐具有良好的解理性且粉碎效率高、耗能低。各因素对原盐粉碎效果的影响顺序为:射流压力卤水喷嘴直径、料液混合喷嘴直径、靶面形状。

Abstract:The comminuting of raw salt observing appearance and analysing component of production which comminuted by high-pressure water jet are conducted．The capability of high-pressure water jet comminuting raw salt the various factors influencing the process of comminuting are studied by using the orthogonal analysis ．These results indicate that high-pressure water jet comminution is advantage in good cleavability high comminuting efficiency low energy consumption etc．The order of the factors effecting on comminuting efficiency is pressure of water jet diameter of nozzle for water diameter of nozzle for materials and shape of target．
