Limestone jaw crusher movable jaw hole wear is the more common form of damage, after many years of practical experience, crusher manufacturers summed up the following two repair methods.

repair welding inner hole method

If the limestone jaw crusher is use steel make movable jaw, then this repair method is the most appropriate, with manual electric arc welding in the inner hole surface wear uniform surfacing layer, and then press fit tolerance requirements to the reaming, in order to achieve the purpose of reasonable matching and the outer diameter of the bearing.

This method of inner hole welding layer is thinner, and the movable jaw wall thickness is larger, so the welding is generally not deformation, no special requirements for the welding process, but in processing the hole should be the verticality control well within the line and broken jaw hole center machine movable jaw two end, in order to ensure activities jaw and other parts of the matching relation and the matching accuracy.

insert repair of internal hole method

Method of internal hole with set to repair the movable jaw, although the process is complex, but it is suitable for cast iron material of the movable jaw, if again hole wear, as long as can replacement of the inner sleeve , can greatly simplify the repair process. Inner hole bushing to be boring, then in the hole with a special sleeve to compensate for wear, and finally by the matching requirement will be processed to the basic dimensions.

Limestone jaw crusher by using the method of inner hole bushing repair the movable jaw, not by the movable jaw material limitations, so it is especially suitable for the welding of the poor performance of the movable jaw material. After the repair, if again appear hole wear, can be used to replace the bearing jacket to repair, simplify the repair process.

Small jaw crusher jaw hole assembly has two kinds of forms, Babbitt alloy sleeve is installed in the hole or holes in the installation of the rolling bearing. If the wear bushing Babbit, the spare sleeve replaced, then the repair or re pouring for Babbitt alloy sleeve.

The limestone jaw crusher often mounting inner holes of the rolling bearing, often encounter the outer ring of the rolling bearing looseness and abrasion of the inner hole, the repair method can according to the above describes the welding or inlay method to repair the limestone jaw hole.
