K-Tron volumetric feeders have exchangeable screw design choices; you can handle a wide range of applications involving prefeeding, feeding or batching of materials that have a consistent density, particle size and moisture content.

Use Single Screw Feeders to handle free-flowing materials such as pellets and powders. Use Twin Screw Feeders to handle more difficult materials such as pigments, sticky, bridging or flooding powders, fibers and fiberglass.

In principle, volumetric feeding is the simplest, most economical feeding solution available. Bulk material is held in a hopper and constantly fed into a process per unit of time. A gravimetric feed rate may be inferred through a calibration process where a timed sample is taken and weighed, and screw speed adjusted accordingly. Although there is no weight feedback to assure feeding accuracy over time, this may not be a concern for materials with consistent bulk density.
