Our company offers Volumetric screw feeders, which are used in various industries for the metering of material into a production process. 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. These screw feeders are usually used when the material is toxic or dusty and which requires an enclosed device. These are available at most reasonable prices.
