ABSTRACT:
A granular material processing apparatus provided with an improved sealing arrangement for the granular material, which is so arranged that, instead of employing an ordinary packing member conventionally used for a known sealing arrangement, a packing portion is formed by the granular material itself present in the processing apparatus for tightly closing the gaps or clearances between stationary container members and movable processing members, thereby to completely eliminate troubles, spilling of the granular material and mixing of foreign matters into the granular material arising from abrasion or deterioration of a packing member, if such packing member should be employed.
