How to ruduce he loss of the movable jaw hole?

In the mining of mineral resources, the most commonly used mineral processing equipment is the jaw crusher.The work of the jaw crusher is to use the kinetic energy generated by the jaw to exert extrusion, bending, impact, shear and grinding on the materials to break the materials, so the jaw plate is also the most vulnerable parts, the common form of jaw abrasion is the jaw grinding hole, how to reduce the loss of jaw crushing motor jaw hole to the minimum?
1. Adopt the inner bore bushing, use the tool to wear the inner bore bore bigger, select two bearing bushing, the outer diameter and the inner bore of wear jaw, the inner bore and the outer diameter of rolling bearing match closely, the bearing bushing is set in the inner bore of movable jaw, in order to ensure the set is stable, between the jacket and the inner bore of movable jaw can be installed 6 stable nails.This method requires attention to the thickness of movable jaw wall, the diameter of original inner hole of movable jaw, the thickness of bearing jacket wall and the thickness accuracy of bearing outer seat ring.This method has good adaptability to movable jaw material, especially to movable jaw material with poor welding performance.

2. Re-weld the inner hole. This method is especially suitable for the movable jaw made of cast steel.Firstly, manual arc welding was used to fill the worn inner hole with surfacing welding, and then the cavity was enlarged again to match the bearing outer diameter reasonably.Note that the welding layer of the inner hole should be thin, because the thickness of the movable jaw wall is large, so as to ensure that no deformation will occur in surfacing welding. When reprocessing the inner hole, ensure that the Central Line of the inner hole is perpendicular to the two end faces of the movable jaw, so as to ensure that the movable jaw forms a good matching relationship and precision with other parts.

Operation of Jaw Crusher

图片
Operation Instructions of Jaw Crusher 1.The preparation before starting: (1) Inspect each bearing to ensure whether it lubricates well, and whether there is enough lubricating grease on the toggle plate joints and bearing inners. (2) Check carefully whether all fasteners are totally fastened. (3) Check whether the drive belt is under good condition, and change the belt if any damages can be found. When there is grease contamination on the belt or bell wheel, it can be clean up with a clean dishcloth. (4) Check whether the protective device is under good condition, if there are any unusual events and safety hazards conditions, should correct them and report. (5) Check whether there are any ore or other impurities inside the crushing cavity. 2.The starting of the crusher (1) After inspecting the machine and transmission parts are under good condition, the machine may starts. (2) This machine can only start under empty load conditions. (3) After having started the machine, shut down the

What factors affect the output of cone crusher

What factors affect the output of cone crusher There are three main factors influencing the productivity of cone crusher : the number of times of the swing of the cone;The length of the parallel crushing area;The size of the engagement Angle.These three aspects directly determine the output of cone crusher. 1.the number of times of the swing of the cone The swing times of the crushed cone is one of the key factors affecting the crusher productivity. Because of the limitation of the meshing Angle of the crushing cavity and the parallel ore discharge area, the crushed ore is discharged along the taper inclined plane mainly by gravity and vibration.When the number of spindle rotation increases, the ore is easy to be discharged, but the number of rotation is too high, which is not conducive to ore discharge, sometimes resulting in faster speed and unable to produce.Therefore, the number of swing of the broken wall has a certain constraint on the improvement of productivity. 2.The l
