DEVICE AND METHOD FOR DOSING AND MIXING SOLIDS OF FESTPULVER IN TECHNOLOGICAL FLOWS FOR THE CONVERSION OF PLASTIC MATERIALS

摘要

An apparatus (1) for dosing and mixing solid powders in technological processes for converting plastic materials, comprising an assembly (2) for dosing the solid powders to be mixed with a first process liquid before mixing with an additional process liquid, the dosage assembly (2) comprising at least one hydraulic cylinder (10a, 10b) for introducing the powders at a preset pressure which is correlated to the pressure of the first process liquid kept at a controlled pressure.
