Provided are a granular excreta treating material which has high absorbing property and is expected to exhibit disintegrability and aggregativeness, a production method thereof, and an extrusion type compressive granulating apparatus thereof. The granular excreta treating material has absorbing property and is formed by extruding and granulating a raw material via a granulating hole, wherein the granulating hole includes a small diameter hole and a large diameter hole which are continuous to each other in the axial direction of the hole, in which the small diameter hole forms a compression zone, and the large diameter hole forms a non-compression zone, and in which the raw material is compressed at the compression zone, swells at the non-compression zone, and is cut into granules by a cutting blade rotating along an outlet surface of the non-compression zone. |
