Building a shear crushing specific energy consumption ...
With the help of crushing specific energy consumption, a fractal prediction model of crushing energy consumption was established, and RR model was used to correct the model. Finally, this paper verified the effectiveness of the corrected model by a series of tests that compare actual measured values, predictive values from the uncorrected model and predictive values .
