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
→Ball millsgive a controlled final grind and produce flotation feed of a uniform size.Ball millstumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed toball mills(dry basis) is typically 75 vol.-% ore and 25% steel
→Our PERI AutoCharge Mill Grinding Ball Charging System is designed to provide a controlled continuous supply of balls to maintain consistent ball loading in the grinding mill. Continuously charging grinding balls will allow your mill to maintain a consistent power draft, charge volume, ore feed rate, or consumption average (kg/t)
→When charging a ball mill, ceramic lined mill, pebble mill, jar mill or laboratory jar use on a jar rolling mill it is important to have the correct amount of media and correct amount of product.

→Abstract: In semi-autogenous grinding (SAG), the grindingmillinventory, (i.e. volume of totalcharge, volume ofball charge, etc.) is important in determining the optimum operating condition for maximum production (tph), minimum specific energy (kwh/t) or lowest cost ($/t). A two-dimensional graphical method is presented for determining the actualball chargewithin the totalchargewhen

→Aball millalso known as pebblemillor tumblingmillis a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of themillvolume and its size depends on the feed andmillsize
→Rodmillsare very similar toball mills, except they use long rods for grinding media. The rods grind the ore by tumbling within the themill, similar to the grinding balls in aball mill.To prevent the conditions leading to rodchargetangling, the length to diameter ratio is maintained at 1.4 to 1.6.Rodmillsaccept feed up to about 50 mm (2 in.) and produce a product in the size range of
