Abstract
In a mixing kneader for carrying out mechanical, chemical and/or thermal processes, having at least two rotating shafts (5, 6) with their axes parallel, disk surfaces (21) with kneading bars (25) fitted to their periphery are to be provided at least on the one shaft designated as the main shaft (5). These kneading bars will be swept by a cleaning and/or kneading and transporting elements (7) which are fitted to the other shaft designated as a stripping shaft (6). In this arrangement, the kneading bars (25) of two neighboring disk surfaces (21) on the main shaft (5) maintain a mutual spacing (a), through which passes the cleaning and/or kneading and transporting element on the stripping shaft (6).
