Ball mill is the key equipment for grinding after the crushing process, which is widely used in the manufacture industries, such as cement, silicate, new building material, refractory material, fertilizer, ferrous metal, nonferrous metal and glass ceramics and can be used for the dry and wet grinding for all kinds of ores and other grind-able materials.
Ball Mill The balls which could be of different diameter occupy 30 50 of the mill volume and its size depends on the feed and mill size The large balls tend to break down the coarse feed materials and the smaller balls help to form he fine product by reducing void spaces between the balls Ball mills grind material by impact and attrition
DetailsThe starting point for ball mill media and solids charging generally starts as follows 50 media charge Assuming 26 void space between spherical balls nonspherical irregularly shaped and mixedsize media will increase or decrease the free space 50 x 26 13 free space Add to this another 1015 above the ball charge for total of 23 to 25 product loading
DetailsThe ball mill is a tumbling mill that uses steel balls as the grinding media The length of the cylindrical shell is usually 1–15 times the shell diameter Figure 811 The feed can be dry with less than 3 moisture to minimize ball coating or slurry containing 20–40 water by weight
