the operating principle of the ball mill

The disadvantages ofball millsinclude their considerable metal consumption and deterioration grinding media, as well as a lot of noise. Most of the energy useless lost duringball milloperation, leading to low itefficiency. But even a significant specific energy consumption for grinding material compensates beneficial effect by usingmill

fuzzy logic based on line efficiency optimization control

Aug 27, 2007·Fuzzy LogicBasedOn-Line Efficiency Optimization Controlof a Ball Mill Grinding Circuit. Abstract: Grinding circuit must provide stable particle size distribution and should also operate in a way to maximize mill efficiency. Fuzzy logic based on-line optimization control integrated in an expert system was developed to control product particle size while enhancing mill efficiency in a ball mill grinding …
