The main function of a copper ball mill is to grind the ore particles to a suitable size for mineral separation. The grinding process involves rotating the mill barrel, which contains grinding media (such as steel balls or ceramic beads) and the copper ore. As the barrel rotates, the grinding media cascade and collide with the ore, producing ...
