Using Ball Mills to Extract Gold from Ores
Many early mines used stamp mills but many operations today find that ball mills are more functional for smaller operations and perform well with the modern equipment we have available now such as combustion engines. The Function of a Ball Mill . To perform its functions the ball mill operates on the principle of impact and attrition.
A BASIC UNDERSTANDING OF THE MECHANICS OF ROLLING MILL ROLLS
