Vibrating Spider Arms
From the pictures supplied (please see image 1), it can be seen that the corners of the spider arm wear plates are the first point for the jigsaw to form and from which it grows to eventually block the mouth of the crusher. If these wear plates could vibrate, they could loosen the initial build up and prevent jigsawing from occurring. This solution is unlikely to solve any oversize from blocking the mouth crusher.
