The present invention is a vertical swing hammer crusher formed to be detachably coupled by bolts and nuts, 'b' shaped bits are welded to the upper and right portions of the hammer starting part wear life is to use the life of the horizontal hammer In order to economically replace the inner surface of the worn vertical swing hammer crusher, it is possible to extend it more than twice and to replace only the part where the wear occurs by forming the detachable arc shape according to the rotation direction of the hammer crusher. The present invention relates to a vertical swing hammer crusher consisting of a bit hammer and a detachable arc shaped plane that economically extends the life of the plain surface.

In general, the principle of the crusher used for the production of masonry aggregates and recycled aggregates is mainly composed of compression crushing to crush the aggregate with the aggregate between the compression plates. However, the aggregates of aggregates produced by the conventional crusher using the compacting action tend to be produced as segregation, and since the aggregates and the mortar are crushed at the same time, the peeling effect of the mortar attached to the circulating aggregate is also insufficient. there was.

In particular, the particle size of the aggregate discharged through the conventional crusher is discharged only to a certain size or less, it is difficult to match the particle size, shape, etc. proposed by the recycled aggregate for concrete (KS F 2573) or crushed aggregate for concrete (KS F 2527) In addition, the aggregate production rate of less than 5㎜ is also small, it is investigated that it is not suitable for the circulating aggregate standards for road construction.

This is because the shape of the area where the striking member (= horizontal hammer) is in contact with the inner surface of the housing (= vertical swing hammer crusher) is an angular shape, and wear is easy when the aggregate is broken, and the friction fracture between the aggregate and the aggregate is weakened, and thus the skeleton There was a problem that the crushing falls significantly, and the problem that the wear occurs more easily than other parts of the hammer even in the top where the falling aggregate hit the most.

In addition, the impact member exerts an impact on the inner surface of the housing by the strong force during the crushing of the aggregate, and the entire inner surface of the housing has to be replaced because the inner surface of the housing is worn in a wavy shape.

In order to solve the above problems, the present invention changes the material and shape of the hammer to extend the service life of the horizontal hammer, and at the same time economically replaces the inner surface of the worn vertical swing hammer crusher bit type.
