Abstract
The invention relates to a method and a device for dosing bulk material, in particular plastic granulate, for machines processing plastic granulate, in particular for injection molding machines. Different amounts of different plastic granulates are filled in batches according to freely adjustable formulas and each individual type of a plastic granulate, such as for example virgin material, masterbatch, additives and/or material to be ground, is successively released into a weighing container from a material hopper (2) via a material valve. Weighing occurs in the weighing container (4) and the formula amount is subsequently blended into a mixer. The amount of plastic granulate, preferably the virgin material and/or material to be ground, disproportionately high for the formula is filled into the weighing container (4) from at least two material hoppers (2) by means of a parallel filling or multiple parallel filling.
