Jaw Checks
Jaw faces
4. Monitor the wear on the jaw liners from new and
turn or renew them when 95% worn.
5. Monitor and check the wear of the jaw liners
regularly.
6. DO NOT allow the jaw liners to wear below the
bottom of the grooves. Any wear below this
will result in the support block at the base being
worn.
7. Continued crushing with heavily worn jaws
increases the crushing forces and power
consumption. This may limit the minimum
setting on hard materials.
1. Check discharge opening with callipers and
adjust as necessary, to the required settings.
2. Check the jaw and side cheek securing nuts
daily.
Jaw Crushers
Wear Checks
3. In high ambient temperatures, grease the jaw
eccentric shaft, see servicing - lubrication.
8. The jaws are double ended can be turned to use
the other end, if one end has become worn.
The worn area then being at the top of the
crusher.
Toggle Plate and Seats
9. The toggle seats and toggle plate should
be checked for wear as this can eect the
operation of the spring system and in extreme
cases cause the mechanism to fail [the greater
the wear the closer the spring bracket gets to
the jaw – collision could occur].
