Description

Shot blasting device

The present invention relates to a large shot blasting apparatus for deburring a large amount of a large amount of processed material.

The conventional shot blasting apparatus is used in the case of removing fine burrs attached to a small molded product. However, recently, there is a demand for removing burrs attached to a large molded product, and as a countermeasure, the size of the cylindrical body is increased, and the projection material and the projector are increased in size. However, in such a measure, the inside of the cylinder is used. The agitating plate is a rectangular plate. If the size of the treatment material is increased, the following disadvantages are caused: the projection material is hindered, or the agitating plate is mounted at a mounting angle perpendicular to the bottom surface of the cylinder, so that the treatment material is processed. It is not carried on the stirring plate and cannot be fully stirred.
