Method for dosing bulk material

摘要

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.

1. Method for dosing bulk material for machines processing plastic granulate wherein different amounts of different plastic granulates are filled in batches according to freely adjustable formulas and each individual type of a plastic granulate is successively released into a weighing container from material hoppers via one material valve each, weighed in the weighing container, and the formula amount subsequently blended into a mixer, wherein the amount of plastic granulate disproportionately high for the formula is filled into the weighing container from at least two material hoppers by a parallel filling or multiple parallel filling, wherein the parallel filling or the multiple parallel filling is stopped shortly before achieving the target amount and in that the filling of the weighing container only occurs from one material hopper via a material valve to achieve the target amount of the parallel filling.
