| Title: Heating process and damage evaluation of hard rock under microwave irradiation | |
| Abstract: The interest in microwave processing of materials especially facilitating breakage is highlighted recently due to its potential for decreasing energy consumption and improving process efficiency. Fundamentals and industrial applications of microwave heating are introduced in the lecture. Multi-field theory of microwave-assisted hard rock fragmentation is illuminated. Results of numerical simulation based on two phase model are presented to clarify the temperature gradient, stress and strain states of minerals under microwave irradiation. Damage evaluation of hard rock is quantified according to the crack propagation behavior. Experimental results of microwave heating pyrite-calcite mineral are shown to validate the theoretical model. The research has the significance for the industrialization of microwave-assisted solid breakage. | |
