  • Patent number: 9440374
    Abstract: 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.

  • Patent number: 6011223
    Abstract: The invention relates to a container with a flexible internal part (6), particularly suitable for weighing bulk material, comprising a closure mechanism within the exit area of the internal part (6) as well as at least two partial exits (18, 19) to be charged, located at the internal part (6) for further processing said bulk material. By means of said locking mechanism, it is practicable to press at least one partial area of the flexible internal part (6) laterally from outside against a sword (14) which is located inside within the exit area of the internal part. This way, said sword (14) separates the partial exits (18, 19) from each other, whereby in each case, one of the partial exits (18, 19) is closable.
