High efficiency elevator buckets: modern vs traditional design


Published on

An elevator bucket is an elevator bucket, right? Not anymore. Recent advances in design technology have brought the advent of the modern high efficiency centrifugal discharge elevator bucket. High efficiency elevator buckets push the traditional limits of carrying capacity, input flow and discharge, construction materials and diminished shipping space.

This delivers an efficientdischarge with no impediments andno crevices where product can collect.Clean out is efficient and cross contami-nation is minimized.Tapered bottomsHigh efficiency elevator buckets fea-ture a tapered bottom. This taperedbottom is key to the performance of thehigh efficiency design and is leveraged forseveral advantages. It allows the bucketsto be mounted closely together with aminimum of vertical spacing. This createsa ‘column’ of input material and generatesthe greatest amount throughput possiblein the elevator leg system.Close vertical spacing requires theefficient entry and exit of input materi-als into the elevator bucket string. Thetapered bottom allows the buckets to filland discharge not just from the front, butfrom the sides as well. This style of bucketfeeds more efficiently on the up-leg, butalso in the boot section as well.The tapered bottom allows high effi-ciency elevator buckets to nest insideone another. This makes shipping andstorage more efficient. Traditional buck-ets do not nest and even when packagedto minimize space, it is mostly air thatis being transported. A stack of highefficiency buckets is denser, and as such,qualifies for the most economical freightrates. Additionally, they use less spacein the motor trailer or ocean-shippingcontainer, thereby reducing costs evenfurther. Once at the job site, they occupyless floor space for storage.Wing freeThe ‘wings’ or ‘ears’ found on tradi-tional grain handling elevator buckets donot serve a determinable function either.The origin of the feature is unclear butappears to originate with the first fabri-cated sheet steel buckets of the 1920s.It may have served as a handle for shopwelders to safely grab with their fingersand they tack welded the inside of thebuckets together. There is no evidencethat the wing provides extra guidance formaterial during fill or discharge. Bucketscannot nest for shipping and storage ifthey have this feature. High efficiencyelevator buckets do not have wings orears. Material cost efficiencies are realizedwith the removal of this physical feature.In some cases, weight savings are realizedas well.The advent of the modern high efficien-cy centrifugal discharge elevator buckethas brought industry greater throughputsand cost savings. Now popular in agri-cultural applications, they are becomingmore widely accepted for industrial useas well, where over-sized slower mov-ing elevator buckets have been utilized.A true high efficiency elevator buckethas a smooth interior front face, can bemounted closely together, has a taperedbottom, nests inside one another and hasno wings on the sidewalls."Recent advances in design technology havebrought the advent of the modern high efficiencycentrifugal discharge elevator bucket"Grain&feed millinG technoloGy may - June 2013 | 21More inforMation:UK officeTel: +44 113 2461800Email: 4b-uk@go4b.comUSA officeTel: +1 309 6985611Email: 4b-usa@go4b.comWebsite: www.go4b.comFEATURE
