An agitator ball mill comprises a grinding chamber (1), a rotatably mounted agitator shaft (5), which protrudes into the grinding chamber (1) and on which agitator elements (10, 20, 30), in the form of paddle wheels, are arranged spaced apart from one another axially, and an inlet (6) for supplying material to be ground and grinding bodies and an outlet (7) for removal of the ground material. The agitator elements (10, 20, 30) are constructed in such a way that, during operation, they convey a mixture consisting of material to be ground or dispersed and grinding bodies through their interior outwards away from the agitator shaft (5). In the grinding chamber (1) there are arranged return conveyor elements (17, 27, 37; 47; 57) which are joined to the agitator shaft (5) for conjoint rotation therewith and which convey the mixture laterally alongside and/or between the agitator elements (10, 20, 30) inwards towards the agitator shaft (5). |
