Mill Selection. The first step inmill designis to determine the power needed to produce the desired grind in the chosen ore. The most used equation, for this purpose, is the empirical Bond equation (Bond, 1960, 1961; Rowland and Kjos, 1978).
Get PriceBall millsare simple indesign, consisting of horizontal slow rotating vessels half filled with grinding media of ¼” to 1.5”. The particles to bemilledare trapped between the grinding media orballsand are reduced insizeby the actions of impact and attrition.

Mar 29, 2019·Ball millsare a special instrument used to break up hard solids into a fine powder. They are similar to rock tumblers in that the instrument is a rotating container filled with heavy balls to grind the substance into powder. Ceramic material, crystalline compounds, and even some metals can be ground up using aball mill.
Ball Mill Design. A survey of Australian processing plants revealed a maximumball milldiameter of 5.24 meters and length of 8.84 meters (Morrell, 1996). Autogenousmillsrange up to 12 meters in diameter. The length-to-diameter ratios in the previous table are for normal applications. For primary grinding, the ratio could vary between 1:1and ...

Ball MillsSteelBall Mills& LinedBall Mills. Particlesizereduction of materials in aball millwith the presence of metallic balls or other media dates back to the late 1800’s. The basic construction of aball millis a cylindrical container with journals at its axis.
First, a JarMillgrindability test requires a 5 lb. (2 kg) sample and produces a direct measured specific energy (net Hp-hr/t) to grind from thedesignfeedsizeto the required productsize. The second test, a Bond Work Index determination, results in a specific energy value (net Hp-hr/t) from an empirical formula.
