Abstract： As one of important parts of pulverizing system, ball mill is used widely in coal-fired power plants. However, most pulverizing system can not be operated economically. One main reason is that fill level in ball mill is hardly measured precisely. Different from other ANNs, the learning velocity of CMAC is far more rapid.
