When to change jaw plate?

The ideal situation would be when even wear occurs throughout the jaw plate area, using all the manganese teeth, eliminating the need to execute the “turn”, or change production.

This is impossible, however, because there are areas where we cannot avoid more severe wear than in others, mainly because of the crushing movement geometry, such as in the fixed jaw plate lower tip and the central area of the swing jaw plate, so a turn should be carried out to achieve better performance and use. We recommend a double turn, in other words:

Fixed jaw plate – use until wear of about 50% occurs in the lower area and make the first turn. Make the second turn when wear from 90% to 100% occurs in this new lower area. Conclude using the remaining 50% of the life cycle of this extremity.

From left to right: initial (50%), first turn (90-100%) and second turn (final).

Swing jaw plate – the same procedure is applied to the swing jaw plate because although the wear occurs in the central area, it rarely occurs in the exact middle of the jaw plate.
