Basics of Gravimetric and Volumetric Feeding : Plastics

Feed Rate Basics. In the continuous formulation of plastics the primary purpose of feed rate control is to achieve consistently accurate proportioning of recipe components (resin and required additives) prior to pelletization (in compounding) or end-product forming operations.Feeders produce a precise and controllable discharge rate for the material they are designed to handle.get price

Gravimetric Feeders: The Achilles' Heel of Continuous

During the fill cycle, the downstream feeder is operated in a volumetric mode (i.e., at a constant speed). The feeder then operates in gravimetric mode (i.e., its speed is controlled by measuring the loss in weight of material inside the hopper) after the downstream hopper has been filled. A schematic of a gravimetric feeder is given in Figure 1.get price
