5.2.2 Checking the gap
After installing the crushing plates (18, 22), you must check the gap between the
plates:
To do this, you must remove the belt guard outside (9). The fastening screws of the
belt guard outside (9) are located under the edge protection (8). When the belt
guard outside (9) is removed, the fly-wheel (25) can be turned by hand. Set the
indexing cranked handle (7) to the lowest setting. To do this, unscrew the knurled
knob on the cranked handle (7) and set the cranked handle to the required setting.
Allow the head to snap correctly back into place – this locks the fixed crushing plate
into place. Adjust the movable crusher jaw (21) using the fly-wheel to product the
smallest possible gap between the crushing plates (18, 22). This should be
between 0.5 – 1 mm. Check the gap with a feeler gauge.
You can adjust the gap by removing or adding a compensating plate (20) under the
pressure plate (19) on the fixed crusher jaw (17).
TIP
When operating the jaw crusher, the crushing plates
must not touch with the narrowest gap.
