摘要：
The calculation of the dissipated thermal energy of mineral crushing is of great significance for the reduction of the heat loss in the crushing process. The traditional calculation method is relatively simple, which does not consider practical problems, such as cooling during the crushing process and uneven temperature distribution. This paper used infrared video to record the impact and crushing process of anthracite for more accurate calculation results. Considering the cooling of high-temperature particles and the temperature distribution of particles at different depths, a calculation model for heat dissipation energy was established. Based on this model, the average heat generation efficiency of impact crushing of cubic and disc anthracite specimens reached 9.70% and 4.55%, respectively.
