〔The invention's effect〕

As described above, according to the present invention, pachinko balls can be polished without increasing the width of pachinko islands, and a polishing effect equivalent to or higher than that of a conventional polishing / lifting machine can be obtained. Can be Also, since it is not necessary to increase the width of Pachinko Island, it can be applied to existing facilities.

Further, since a plurality of polishing units are used in multiple stages, a single screw feeder can be relatively shortened.
As a result, the motor torque is transmitted efficiently and the loss is reduced.

Similarly, each polishing unit can be shortened, so that it can be installed relatively steeply even in a space with limited height dimensions. As a result, the pachinko balls discharged from each polishing unit and the polishing The material falls naturally on the return path, eliminating the need for forced transport.

In addition, since the short polishing units can be arranged steeply, the lateral dimensions of the polishing apparatus are compact, the restrictions on the installation place are reduced, and the installation work is also easy.

By circulating the abrasive independently for each polishing unit, it is possible to use a plurality of different abrasives for each polishing unit.
