積するといった現象も起っていた。Conventionally, in this type of threshing equipment, in order to improve the threshing efficiency, processing chambers were installed side by side on the side of the processing chamber, and the second reduced material was returned to the processing chamber. Processing for the second item was carried out in
[Problem to be solved by the invention] However, in this case, due to the equipment configuration, from the exit of the second material conveying device located at the bottom end of the threshing device, to the processing chamber located at the top end of the threshing device. The second item had to be transported to
As the lift height becomes larger, the capacity of the thrower device as a secondary object conveying device inevitably becomes larger, and the conveyance path to the processing chamber becomes longer, which may cause the phenomenon that the conveyed objects accumulate in the hollow at the bend. I was awake.

From the structure, the processing rotor and the wall of the storage chamber, or the processing rotor is provided with processing teeth and the wall of the storage chamber is provided with receiving teeth, and by their cooperation, a fir treatment action or a squeeze is performed on the second reduction product. It is possible to add action and to perform monogranulation treatment. Therefore, it is not necessary to return to the processing cylinder as in the conventional case, but it can be returned to the swinging sorting section, and the lift by the thrower device can be lowered.
