近一、二十年来国内外在研究新的电热破碎方法方面,取得了一定的成绩。美、苏、英、日、荷兰和西德等国家都做了一些工作。这些方法是在近代物理学基础上利用电能直接进行破碎,而不再经过多次的能量转换,通常称作电物理破碎,实际就是电热破碎。 Nearly one or two decades at home and abroad in the study of new electric crushing methods, has made some achievements. The United States, the Soviet Union, Britain, Japan, the Netherlands and West Germany and other countries have done some work. These methods are based on modern physics based on the use of electric energy directly crushing, and no longer after repeated energy conversion, commonly known as electrical physics crushing, is actually electrothermal crushing.
