How does a Rock Crusher Work
The side frames are deep-welded and then "stress-relieved" in the huge annealing furnaces to eliminate possible failure adjacent to welds. The result is a uniformly strong frame that will remain true during the long service life of the crusher. A jaw crusher frames are of sectionalized construction to facilitate handling.
