    Calculate and Select Ball Mill Ball Size for Optimum Grinding

    There are many methods of monitoring the filling level of a ball mill. A first method is based on measuring variations in the power absorbed by the electric motor driving rotation of the drum of the ball mill. A second method is based on measuring the noise level emitted by the ball mill in operation.To fill this gap, this work for the first time in the coal processing sector is going to introduce a type of advanced intelligent method (boosted-neural network “BNN”) which is able to linearly and nonlinearly assess multivariable correlations among all variables, rank them based on their effectiveness and model their produced responses.
