P&Q University Lesson 7

 · Jaw crusher units with extra-long, articulated crusher jaws prevent coarse material from blocking while moving all mounting elements of the crusher jaw from the wear area. A more even material flow may be affected if the transfer from the prescreen or the feeder trough is designed so material simply tilts into the crushing jaw.

Failure Analysis Of Machine Shafts

 · For a fatigue failure to occur, the forces must have been applied many times. There are low-cycle failures but most industrial fatigue failures we''ve seen involve more than 1,000,000 load cycles. A valuable feature of fatigue-failure interpretation is that the crack growth, i.e., the surface appearance, tells how the load was applied.
