Microwave-assisted grinding - IEEE Journals Magazine

In a microwave chamber designed to simulate a continuous throughput operation at 3 kW, the grindability of a taconite ore was improved by 13% at a bulk temperature of 197 degrees C. Because stress cracking occurred at a lower temperature, less energy was consumed, thereby improving the cost effectiveness of microwave-assisted grinding.
