Crusher Blockage. Clearing blocked jaw crushers can be very hazardous and many plant operators have been killed carrying out this task. Blockage incidents can be greatly reduced by supplying rock that is properly sized to match the primary jaw opening. Prevention of oversize in feed material starts at the face with good fragmentation.
Experiment on rock braking was carried out with three loading rates of 0.001 mms, 0.01 mms, and 0.1 mms. The results show that the phenomenon of acoustic emission and electromagnetic emission is produced during the process of loading and breaking rock.
