Abstract: new stochastic model to determine the comminution energy of crusher in open cast mining has been developed. The formula of computing the probability density function of net comminution energy has alse been deduced. According to this model, the dist ribution function of comminution energy can be predicted by the distribution function of input size and discharge size. The test have shown that the stochastic model conforms to the real crush process very well.
