Diamond reserves and production of South Africa are in the front rank of the world. Large-scale development and utilization of diamonds result in production of a large number of diamond wastes. Resource utilization of diamond waste can turn waste into treView Details
Apr 07 2011 · Ball mills are 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 a ball millView Details
The 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 811The feed can be dry with less than 3 moisture to minimize ball coating or slurry containing 20–40 water by weightView Details
The grinding charge in a ball mill consist of cast or forged steel balls These balls are fed together with the feed and consequently ball mills can be in operation for months without stopping The ball size is often in the diameter range of 2075 mm The biggest size is chosen when the mill is used as a primary grinding millView Details
Ball Mill Design A survey of Australian processing plants revealed a maximum ball mill diameter of 524 meters and length of 884 meters Morrell 1996 Autogenous mills range up to 12 meters in diameter The lengthtodiameter ratios in the previous table are for normal applicationsView Details
Another indication of mill loading is the power draw Overloading and under loading will both reduce power draw The ball mill must be run to draw maximum power at all times The operator must manually measure the cyclone overflow and underflow densities regularlyView Details
Ball mills are widely used in cement silicate products new building materials refractory materials fertilizers black and nonferrous metal dressings and glass ceramics The ball mill is suitable for grinding various ores and other materials and is widely used in mineral processing building materials and chemical industriesView Details
The model is equally applicable to ball semiautogenous and autogenous mills and contains a description of the power draw of both the cylindrical section and the coneendsView Details
