Volumetric feeder
A volumetric feeder, on the other hand, does this based on volume in speed.
A volumetric feeder is a dosing system that supplies the production system with a certain volume of material in a set timeframe, based on the so-called displacement principle. In contrast to a gravimetric feeder, the dosing speed of a volumetric feeder should be selected manually, which may vary based on the nature of the raw input materials. For example, masterbatch requires a different speed compared to dosing of liquid or powder input material.
For smaller production processes and companies who are looking to save on dosing equipment, a volumetric feeder is favoured over a gravimetric feeder. Yet, a gravimetric feeder enables one to save heavily on the input material by a more precise feeding process. This means that a gravimetric feeding system usually provide for a higher return of investment (ROI) on a long-term basis.
