摘要 |
<p>A jaw crusher is provided with a pressure relieving system to allow a movable jaw of the crusher to yield in case of an excess crushing load. The movable jaw is urged outwardly by a spring and an hydraulic ram exerts inward pressure on the jaw against the spring action. The ram has a control system for reducing the ram pressure when an excess load is encountered allowing the spring to move the jaw outwardly and after a suitable time delay for re-establishing the pressure within the ram to return the jaw to its inner position against the spring action.</p> |
