the ball mill is a hollow drum closed with loading and unloading end caps, filled with grinding media and rotated around its axis.the drum of the ball mill (pic. 1) is a hollow cylinder of steel, lined inside with armor lining plates which protect it from impact and friction
optimum ball diameter (taggart, 1945). test mills used for media sizing investigations need to be reasonably large (at least 0.4 m in diameter was suggested), depending on size of balls and ore being tested. ball surface wear rate is approximately
1. introduction ball mill is an efficient tool for grinding many materials into fine powder. the ball mill is used to grind many kinds of row materials. there are two ways of grinding: the dry process and the wet process. it can be divided into tubular type and flowing type according to
ball mills give a controlled final grind and produce flotation feed of a uniform size. ball mills tumble iron or steel balls with the ore. the balls are initially 510 cm diameter but gradually wear away as grinding of the ore proceeds. the feed to ball mills (dry basis) is typically 75 vol.- ore and 25 steel.
1. as the name suggests, the ball milling method consists of balls and a mill chamber. therefore over all a ball mill contains a stainless steel container and many small iron, hardened steel, silicon carbide, or tungsten carbide balls are made to rotate inside a mill (drum). 2. the powder of a material is taken inside the steel container.
