When the rocks are about inch or smaller, they are fed as a slurry into the two ball mills each ball mill is turned by a single , horsepower electric motor these mills contain literally hundreds of thousands of threeinch diameter steel balls that pulverize the ore until it is like fine sand or face powder only then are the copper.
Jan 01, 1996 In this study, high-energy ball milling was applied to synthesis in situ nanostructured copper based composite reinforced with metal carbides. Cu, M (M=W or Ti) and graphite powder mixture were mechanically alloyed for various milling time in a planetary ball mill with composition of Cu-20vol WC and Cu-20vol TiC.Ball Mill for Sale. APPROXIMATE CAPACITIES. All ball mills operate on the same principles. One of these principles is that the total weight of the charge in the mill-the sum of the weight of the grinding media, the weight of the material to be ground, and any water in the mill—is a function of the percentage of the volume of the mill it occupies.
