SAMPLE EXTRACTOR "Pelican"
Extractors of this type are used for sampling in vertical pipe systems up to NW 400 mm. Other sizes on request. Such a unit is designed so that its chute will cover the full range of grain sizes in the stream of goods, the frequency of sample extraction being controlled via a time-limit relay. The sampler casing is a sturdy assembly of welded sheet steel. The chute is driven by an electric motor and worm gear unit and has radial and thrust roller bearings. A proximity switch in the casing will move the chute into zero position outside of the stream of materials.
