Centrifugal Bucket Elevators are the most common and efficient way to convey material. It has been serving efficiently and are used to convey free flowing/powered bulk solids, such as, sugar, grains, animal feed, sand, minerals, aggregates, chemicals and more. Centrifugal Bucket Elevators as the name suggest operate at high speed throwing the materials out the buckets into discharge throat by centrifugal force. The Industrial type elevators operate at slower speeds than standard duty-type elevators. In Centrifugal Bucket Elevators the Style AA buckets are used, which are widely spaced on a chain or belt, which operate at speed up to 305 FPM for handling the heaviest industrial material up to 1213 pounds per cubic foot.
Continuous Bucket Elevators, operate at slower speed having buckets spaced continuously. Continuous Bucket Elevators are well designed to handle delicate foods from chemicals, Pharmaceuticals to highly abrasive and impacting materials from sand, gravel to ores and crushed rock.
In Continuous Bucket Elevators, the continuous bucket placement allows the force of gravity to discharge their load onto the inverted front of the preceding bucket. The bucket then guides that material into the discharge throat on the descending side of the elevator. Speeds average 120 FPM for handling up to 775 tons per hour. Continuous elevators can convey material horizontally- vertically-horizontally from one or multiple feed points to one discharge point. These conveyors minimize damage are used to handle light, fluffy materials where aeration of the product must be avoided.
