Study on the Wear Characteristics of Cone Crusher Liner and the Evolution Process of Crushing Cavity Type
In order to study the wear characteristics of the cone crusher liner and the evolution of the crushing cavity at different moments,the liner surface crushing force distribution model is established based on the liner wear theory and combined with the crush pressure crushing simulation experiments.Based on the measurement of fixed cone liner wear by ultrasonic sensors,the liner wear calculation model is used to deduce the conversion relation from fixed cone wear to moving cone wear,and a correction factor for liner wear is introduced to improve the accuracy of the calculation results.Aiming at the liner wear profile fitting problem,a dynamic weighted correction method is proposed,and through comparative analysis of the actual liner wear profile in the field,it is found that the relative errors of the weighted correction of the dynamic cone liner and the fixed cone liner are reduced to 1.9％and 0.7％,respectively.The results show that the proposed method can effectively use the sensor measurement data to calculate the worn liner profile curve and realize the prediction of the worn cavity structure of the cone crusher.
