Screw Feeder Manufacturer

Screw feeders are used in various industries for the metering of material into a production process. ColortronicNA has a full line of screw feeders. Screw feeders can generally be classified into one of two categories: volumetric screw feeders or gravimetric screw feeders. Both types of feeders require precision and accuracy in feeding the material into the process, while both do so with differing techniques. A screw is preferable to a belt when handling certain bulk solids. Screw feeders are usually used when the material is toxic or dusty, requires an enclosed device or headroom is restricted or it required an enclosed device.

Volumetric Screw Feeders

Browse our line of 10 Volumetric Screw Feeders.Volumetric Screw Feeders accomplish their accurate feed rate by maintaining a commanded spread, delivering a specific feed rate of material into the process. they discharge a particular volume of material per unit time. This is done by control of belt speed or screw rpm.
