MAINTENANCE
SERVICE PROCEDURE
CHECK OF WEAR ON MAJOR WEARING PARTS
JAW PLATE
CAUTION
If the machine is used continuously with the crusher chamber excessively charged, premature partial wear will develop on the
tips of jaw plates.
If a work is continued with the partially worn jaw plates, rocks may not be discharged smoothly, eventually resulting in
damages on the jaw plates on account of the worsened partial wear.
Replace the partially worn jaw plates with new ones.
If jaw plates are used beyond their wear limit, a serious damage will be inflicted on the jaw crusher main body itself.
Hatched area : Area of virtual wear
If the bottom tips of fixed and swing jaw plates have been worn off
and reached the wear limit as illustrated in the figure at right, either
reverse or replace them, as the case may be.
CHEEK PLATE
If the residual dimension reaches approx. 15 mm (0.6 in) [wear
amount 15 mm (0.6 in)] on the upper end and approx. 10 mm (0.4
in) [wear amount 20 mm (0.8 in)] on the lower end, proceed with the
replacement.
PROTECTOR
When the residual dimension reaches approx. 10 mm (0.4 in)
[wear amount 12 mm (0.5 in)], proceed with the replacement.
If a partial wear develops on the protector, replace it, too.
