ball mill is an effective means of dispersing solid materials in solids or liquids. ball mills have several advantages which include versatility, low cost of labor and maintenance, the possibility of unsupervised running, no loss of volatiles, and a clean process. the disadvantages are related to discharging viscous and thixotropic mixtures, and considerably lower efficiency when compared with

ball mill consists of a hollow cylindrical shell rotating about its axis. the axis of the shell may be either horizontal or at a small angle to the horizontal. it is partially filled with balls. the grinding media is the balls, which may be made of steel stainless steel or rubber.

In ball mills, steel balls or hard pebbles to break particle based on impact and attrition. 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.
