First we must be clear, the jaw crusher thrust board, also called cubits board, in addition to transfer power to and fro dynamic jaw plate do outside, but also has a safety insurance effect, changing its length also can rise to adjust the role of ore mouth platoon.
When cone crusher crushing cavity things (such as crushing in an iron ball, iron, etc.), for the protection of the equipment is mainly parts are not damaged and use as crusher insurance after thrust board components. With cast iron plate after general thrust moulds overall, in which a trough of some holes open or to lower the cross-section intensity; Also can cast two, then use screws (or rivets) of connecting thrust board, stone crusher.
