A toggle plate is a mechanical component that connects the movable jaw to the rest of the jaw crusher. It acts as a safety device in case of an overload or shock loading. When an object is too hard or too heavy to be crushed, the toggle plate will break or bend, preventing damage to the jaw crusher.

Optimization Program, we helped them optimize the wear parts of its primary gyratory crusher. The first step of the project was to solve challenges the slippery, graphite-rich ore was causing for the primary crusher. We redesigned the chamber profile and boosted the capacity of the critical primary crusher to the desired 3500 tons per hour.
