The role of Movable jaw in jaw crusher

Jaw crusher mainly used as the primary crusher and crushing in mining, building materials, infrastructure, and other departments. In accordance with the size of the width of the feed inlet is divided into large, medium and small three feed opening width greater than 600MM for large machines, feed opening width 300-600MM for medium-sized machine, feed mouth width less than 300MM for minicomputers. Jaw crusher structure is simple, easy to manufacture, reliable work, easy maintenance.

Today, jaw crusher is active in all major production line maintenance is essential, jaw crusher, jaw crushers maintenance, by the dynamic the Hubei and static jaw two jaw crushing chamber, two simulated animalscrusher jaw movement material crushing operation. Control must also attach importance to the activities of the jaw to jaw crusher.

Movable jaw is very important to the running of the jaw crusher, jaw crusher is the most important part, the requirements of the activities of the jaw is also high, only to meet the requirements to play the most important function of the jaw crusher, jaw crusher usethe law applicable to the steel manufacturing activities jaw, manual arc welding wear the uniform bore surface surfacing layer, re-reaming processing of the press with the tolerance requirements, in order to achieve reasonable fit and the outer diameter of the bearing purposes. Jaw crusher run small details, such internal hole welding layer is thin, and the movable jaw large wall thickness, so when the surfacing generally no deformation, no special requirements on the welding process processing within the hole should control the verticality of the inner bore centerline and the activities of the jaw two end faces, to ensure that the activities of the jaw and other parts with the relationship and with precision.
