A production method for animal excretion treatment material and a production device therefor, having a step in which a raw material is pulverized and a pulverized material is obtained and a step in which the pulverized material is granulized. In the step in which the pulverized material is obtained, the raw material is pulverized by a pulverizer (300) and the pulverized material is obtained. The pulverizer (300) has: an insertion port (310) for the raw material a pulverization chamber (320) for the raw material a pulverization mechanism (330) provided inside the pulverization chamber (320) a mesh screen (340) through which passes the raw material pulverized by the pulverization mechanism (330) and having a plurality of openings and a discharge port (340) connected to the openings in the mesh screen (340).本發明提供一種動物用排泄物有關的更合理之構築技術。本發明的動物用排泄物處理材之製造方法及其製造裝置,具有:粉碎原材料獲得粉碎材料的步驟,及將上述粉碎材料製成粒的步驟,獲得粉碎材料的步驟是藉粉碎機(300)將原材料粉碎獲得粉碎材料,粉碎機(300)具有:原材料的投入口(310);原材料的粉碎室(320);設置在粉碎室內(320)的粉碎機構(330);使得藉粉碎機構(330)所粉碎的原材料通過,並具有複數開口的網篩(340);及與網篩(340)的開口連續的排出口(350)。300‧‧‧粉碎機310‧‧‧投入口320‧‧‧粉碎室330‧‧‧粉碎機構331‧‧‧旋轉體332‧‧‧羽狀體340‧‧‧網篩350‧‧‧排出口MD‧‧‧機械方向
