In ball mills, steel balls or hard pebbles to break particle based on impact and attrition. A rotating mill charged with media and ore is lifted against the inside perimeter. Some of the media falls and impacts the ore particles at the bottom of the mill. The rest of the media cascades and, in the process, creates particle breakage by attrition.

Heat balance equation is considered for the overall mill. Heat balance equation is given as: (8) Q ̇ i n − Q ̇ o u t = Q ̇ a c c. Q ̇ i n represents the rate of heat flow entering the mill,which consists of heat flow in the mixed primary air, raw coal, moisture in raw coal, and heat generated by grinding .It is represented as: (8a) Q ̇ ...
