| Abstract: | The accurate ball-load-addition method,which semi-theory formula calculates the diameter of ball,crushing statistical mechanics principle directs ball matching of initial loading ball,adding balls according to diagraphy,is adopted at Ⅲseries grinding of Dahongshan copper mine in Yunnan province.The new method improves particle characteristic of the grinding product and classified condition,enhanced the mineral liberation degree,classified efficiency,productivity of grinding machine,the recovery and the grades of concentrate,reduced the overgrinding,decreased the consumption of the steel ball,obtained the remarkable economic efficiency.The production practice proves the new method of accurate ball-load-addition can improve the scientificity and reliability of grinding process. |
