What is difference between High energy ball milling and...
There is no fundamental difference, only the attritor with the same mass of equal balls grinds 5-10 times faster. Seen from the other side, only small attritors exist, and the large ball mills are anyway more efficient than small attritors. From a purely economic point of view, the attritors have little meaning, ball mills are cheaper,...Read More
