PROBLEM TO BE SOLVED: To provide a continuous system for kneading, granulating, and drying that can continuously subject a raw dry powder material and a solution of a binder to mixing, granulating and drying to produce granules for molding having a narrow grain size distribution, thereby improving productivity.SOLUTION: A continuous system for kneading, granulating, and drying comprises: a kneader that includes a supply port of a raw dry powder material, a supply port of a solution of a binder, and a discharge port of a kneaded material and continuously mixes the raw dry powder material and the solution of a binder an extrusion granulator that includes a supply port of the kneaded material, an extruding blade, and an extruding die and continuously produces wet granules from the kneaded material and a flash dryer that includes a dryer pipe, a supply hopper of the wet granules, a supply device of a gas for conveying and drying the granules, and a separator of the dry granules and the gas and continuously dries the wet granules. The discharge port of a kneaded material and the supply port of the kneaded material, and the extruding die and the supply hopper of the wet granules, are directly connected respectively so that the raw dry powder material and the solution of a binder may be continuously subjected to mixing, granulating, and drying.COPYRIGHT: (C)2014,JPO&INPIT【課題】本発明の目的は、乾燥粉体原料と結合剤溶液を連続的に混合、造粒、乾燥して粒度分布の狭い成形用顆粒を製造することができ、生産性の向上を図ることができる連続混練造粒乾燥システムを提供することにある。【解決手段】乾燥粉体原料供給孔、結合剤溶液供給孔、および混練物排出孔を有し、乾燥粉体原料と結合剤溶液を連続で混合する混練機と、混練物供給孔、押出羽根、および押出ダイを有し、混練物を連続で湿潤顆粒とする押出造粒機と、乾燥管、湿潤顆粒供給ホッパ、顆粒の搬送および乾燥用ガス供給装置、および乾燥顆粒とガスの分離装置を有し、湿潤顆粒を連続で乾燥する気流乾燥機で構成され、前記混練物排出孔と前記混練物供給孔、前記押出ダイと前記湿潤顆粒供給ホッパをそれぞれ直接接続して連続的に乾燥粉体原料と結合剤溶液の混合、造粒、乾燥を行えるようにした。【選択図】図1
