Jaw crusher thrust plates, also known as push plates, brackets, etc., are the simplest, easy to manufacture and replace parts in the entire stone crusher. In the smashing role can not be underestimated, SBM Heavy Industry reminds the majority of users in the use of the crusher, pay attention to the wear condition of the jaw crusher thrust plate. The thrust plate supports the movable jaw and transmits the crushing force to the rear wall of the frame, and at the same time acts as a safety device for the crusher. Its section size is designed according to the crusher's self-breaking when overloaded. It also divides the thrust plate into two sections, and the middle part is bolted. The strength of the bolt is deliberately weak. When the thrust plate is broken, it must be replaced after overload. This often lengthens the downtime. To avoid this, a hydraulic protection device that prevents over-absorption has been developed.
