A bucket elevator is the same mechanism of normal elevator, where it moves up and down vertically to bring up the bulk materials. A bucket elevator design is also simple as it states, it contains bucket, a belt to carry the buckets and transmit the pull, a mean to drive the belt. There are basically two types of bucket elevator designs, it is centrifugal bucket elevators and continuous bucket
. elevators. The former one will operate at higher speeds to throw the material out of the bucket, where the later will operate at a lower speed and used for fragile materials and are closely spaced on the belt or chain.
