When you are looking for a way to lift your grains, sugar, coffee, flakes, tea or other materials in significant amounts to a greater height, bucket elevators do the trick! Elevating bulk materials is done best by means of these types of elevators. The elevators are built with a set of buckets to contain materials like grain or fertilizer, an oil and grease belt to move the buckets, a mechanism to move the belt and accessories designed to load the buckets for transporting the materials. Because bucket elevators are elevators as well as conveyors, they are able to transport bulk materials both horizontally and vertically. The big advantage of this specific type of elevators over for example belt conveyors or hoppers, is the limited space bucket elevators need. Compared to the aforementioned options, bucket elevators take up a fraction of the area. Other advantages of these elevators are the following:

  • Handle a wide variety of bulk materials
  • Designed to operate in dusty environments and under all weather conditions
  • Reliable
  • Economical solution
  • Little maintenance
  • No need to change your product

Which type of Bucket Elevators do I need?

There are several types of elevators you can purchase to lift your bulk materials. So how to determine which one is most suitable for you? The very first thing you need to consider is the material you would like to transport. Whether this is dusty or clean, lightweight or heavy, fragile or firm, large or small, etc. Each of these factors has considerable influence on the efficiency of you bucket elevator. Essentially, there are three types of these specific elevators: Centrifugal, Continuous and Positive Discharge elevators. As the name already reveals, Centrifugal Bucket Elevators contain a speedy rotating element (1.3 to 3.5 meter per second) and require the buckets to be spread from one another. Continuous Bucket Elevators on the other hand, move in a much slower pace (1 to 1.3 meter per second) and allow the buckets to be placed directly alongside one another. This reduces the chance of materials spilled. Lastly, Positive Discharge Bucket Elevators operate best with materials that are stuck to the buckets’ sides and rotate at the slowest pace (0.8 meter per second), which allows for the transport of larger and heavier materials and buckets.

Subtitle: Capacity and size

With different types of elevators come different capacities and sizes. This means there is a bucket elevator for everyone and every purpose. In general, the elevators have a maximum capacity of 20 to 1,000 tons an hour, carried by an average of 3,5 to 10 buckets per meter. Besides, the height varies from 0 up to 60 meters. For the belts, the breaking strength ranges from 500 to 1,000 newton per millimetre and the belts’ width varies from 150 to 1,200 millimetres. Of course, you can decide for yourself which specific type of elevator you need. However, obtaining advise from the experts is always a good idea. Many elevator producing companies offer free council on the most efficient bucket elevator for your purpose. Do not hesitate to contact them prior to your purchase.
