PROBLEM TO BE SOLVED: To provide an extrusion compression granulator of a granular excrement-treating material which has a high water-absorbing property and is expected to aggregate while being promoted to collapse.SOLUTION: The extrusion compression granulator includes: a die table 1 in which multiple granulating holes 2 are put through a space rib 6 radially provided on a lower surface of the die table 1 a pressurizing rotation wheel 3 for pressing the raw material in each granulating hole 2 of the die table 1 and a breaking blade 4 for breaking the raw material pressed from an outlet of each granulating hole 2 of the die table 1 to granulate. The breaking blade 4 is provided with a free space 8 in the board thickness of the space rib 6 on an outlet surface side of the granulating hole 2. A compression zone Z1 is formed in the granulating hole 2. A non-compression zone Z2 is formed in the free space 8. The raw material is swollen in the non-compression zone Z2 after being compressed in the compression zone Z1. The raw materials is broken to granulate by rotating the breaking blade 4 along the outlet surface of the non-compression zone Z2.COPYRIGHT: (C)2012,JPO&INPIT【課題】 吸水性が高く、且つ、崩壊を促しながら塊状化が期待できる粒状排泄物処理材を製造できる押し出し式圧縮造粒装置の提供。【解決手段】 多数の造粒孔2を貫設したダイステーブル1と、該ダイステーブル1の下面に放射状に設けたスペースリブ6と、上記ダイステーブル1の各造粒孔2内に原料を押し込む加圧回転輪3と、上記ダイステーブル1の各造粒孔2の出口から押し出された原料を粒状に折断する折断ブレード4とを備え、上記造粒孔2出口面側に上記スペースリブ6の板厚分の遊間8を存して折断ブレード4を設け、上記造粒孔2で圧縮ゾーンZ1を形成し、上記遊間8で無圧縮ゾーンZ2を形成し、上記圧縮ゾーンZ1で原料を圧縮した後上記無圧縮ゾーンZ2で膨潤を促し、該無圧縮ゾーンZ2の出口面に沿い折断ブレード4を回転させて粒状に折断することを特徴とする。【選択図】 図2
