Microwave irradiation, as a heating source, has potential applications in mining industry. Microwave irradiation makes physical impacts on brittle rock particles that transform its power draw trend during comminution. This potentially improves the raw material supply. In this research, an instantaneous power draw analysis is applied to detect the microwave heating impact on the particle breakage mechanism during single-roll crushing. Microwave energy is reducing the duration of high resistance zone of crushing trend, which provides shorter crushing time as well as lower crushing energy saving.
