Bucket elevator compared totube chain conveyor

Advantages of tube chain conveyors

  • Less grain destruction at accordant product charge and discharge
  • Suitable for coarser bulk materials and larger grain sizes
  • Higher conveyor capacities possible
  • Larger conveyor heights possible

Advantages of tube chain conveyors

  • Permanently dust-tight system
  • Easy to charge and discharge
  • Far easier cleaning because of its design with almost no dead space
  • Multiple inlets and outlets possible
  • Less maintenance necessary since vertical bulk solids handling does not require any tensioning stations
  • Pressure shock resistant and flame propagation proof conveyor system
  • Many variations possible due to its  flexible layout

Bucket elevator

Bucket elevators (also called bucket conveyors) are continuous conveyors used to vertically convey all kinds of bulk materials.

A bucket elevator has a top station (with a drive shaft, motor, and gear drive) and a bottom return-end station. The steel elevator shafts in which the buckets are moved up and down between the redirecting stations are referred to as “shafts”, “trunking“ or "bucket Elevator legs”.

In a bucket elevator, V-shaped buckets made of steel or plastic are attached to a pulling element that moves in a continuous loop, i.e., a roller chain (in chain-driven bucket elevators) or a belt (in belt-driven bucket elevators). These buckets continuously are loaded with material by means of hoppers or chutes. The material is then conveyed upwards and is tipped into a discharge chute behind the top redirecting station.

Depending on their overall width, their bucket capacity, and the height that must be traversed, bucket elevators can require a large amount of power. A bucket elevator’s height is limited by the tare weight of its buckets and chains, and rarely exceeds 120 meters.
