The invention relates to a device (1) for producing polymer agglomerates, comprising a compounder (2) having a housing (21) and a twin screw (22) arranged therein as well as a plurality of material inlets (3, 4) for admission of a polymer and additives, tempering units for heating the mix comprising polymer and additives, at least one degassing unit (5) and an outlet (23) and an agglomerating vessel (11) having an agglomerating tool (8) and a cooling tool (10). The agglomerating vessel (11) is connected via a connection channel (6) to the outlet (23) of the compounder (2), wherein the twin screw (22) of the compounder (2) is designed as a co-rotating twin Screw (22) and the agglomerating tool (8) of the agglomerating vessel (11) is arranged in the fall direction of the mix below the connection channel (6) and comprises mutually engaging rotors (81) and stators (82) for producing agglomerates of defined particle size. The invention further relates to a method for producing polymer agglomerates.
