Vacuum-weighing systems for precise dosing and weighing of bulk materials
In automated raw material feeding, large and medium-sized components must be weighed accurately and reliably transferred to the subsequent process steps. AZO vacuum weighing systems combine pneumatic conveying with precise weighing, thereby ensuring consistent product quality.
High weighing accuracy thanks to optimized conveying systems
In a single-tube system, the weighing control compensates for variations in product carryover caused by varying conveyor lengths. The multi-tube system further reduces product carryover using valve switches with a fresh air valve. As a result, it achieves greater weighing accuracy than the single-tube system.
Central Weighing Systems for High Throughput
At many raw material feeding stations and consumer points, a central weighing system consolidates the components into a central conveyor scale. After weighing, the batch is transferred to a receiving hopper and from there is transported by pressure feeding to a kneader, mixer, or agitator. Meanwhile, the next batch can already be prepared. This increases throughput and enables the efficient supply of multiple consumers.
Flexible system designs for a variety of production requirements
Whether it’s a single-pipe, multi-pipe, or central weighing system: Choosing the right design ensures a raw material supply tailored to the number of feed points, the consumers, and the required weighing accuracy. Clean product feeding and the precise coordination of control and process technology support reliable production processes.
