Evaluation of a laboratory rod mill when grinding bituminous coal

The tests were conducted using a 193.5 mm diameter and 245.0 mm long laboratory rod mill, which contained steel rods at a volume loading of 23%. The mill was operated at 70% of critical speed for various grind times. A locked-cycle test was also performed to simulate continuous grinding conditions.
