Continuous Vs. Positive Discharge Bucket Elevator Systems

Continuous Vs. Positive Discharge Bucket Elevator Systems

When it comes to transporting bulk materials vertically, bucket elevator systems are the go-to solution for many industries. These powerful mechanisms are essential for a variety of applications, from agriculture to mining, and they come in different types to suit specific needs. Two of the most common types are Continuous Bucket Elevators and Positive Discharge Bucket Elevators. Each has its unique features, advantages, and applications. In this blog post, we’ll dive into the world of Continuous vs. Positive Discharge Bucket Elevator Systems, helping you choose the right one for your operations.

Continuous Bucket Elevators

Continuous Bucket Elevators are designed to handle fine or fragile materials with the utmost care. They operate at a relatively slow speed, which minimizes product damage and degradation. This type of elevator has buckets that are closely spaced, allowing for a continuous flow of material without spillage. The design is ideal for materials that are light, fluffy, or need to be handled gently.

Key Features:

  • Buckets are closely spaced, ensuring a continuous flow of material.
  • Operates at a lower speed to minimize product damage.
  • Ideal for handling fine or fragile materials.


  • Food processing (grain, sugar, flour)
  • Chemical industry (plastics, fertilizers)
  • Other industries requiring gentle handling of materials

Positive Discharge Bucket Elevators

On the other hand, Positive Discharge Bucket Elevators are designed to handle a wide variety of materials, especially those that are sticky or tend to compact. This type operates by elevating the material to the head section of the elevator, where a combination of centrifugal force and gravity helps to discharge the material. The buckets are spaced further apart and travel at a higher speed compared to Continuous Bucket Elevators. This design ensures effective discharge of materials, reducing clogging and ensuring efficient operation.

Key Features:

  • Buckets are spaced further apart and travel at a higher speed.
  • Designed to effectively handle sticky or compact materials.
  • Utilizes centrifugal force and gravity for material discharge.


  • Agriculture (feed, seed, grain)
  • Mining (coal, minerals)
  • Industries dealing with sticky or hard-to-handle materials

Making the Right Choice

Choosing between a Continuous and a Positive Discharge Bucket Elevator depends on several factors, including the type of material you’re handling, the required handling capacity, and the nature of your operation. Here are some considerations to help you make the right decision:

  • Material Characteristics: Fine, fragile materials are better suited to Continuous Bucket Elevators, while sticky or compact materials are ideal for Positive Discharge systems.
  • Handling Capacity: Consider the volume of material you need to move and choose a system that can handle your requirements efficiently.
  • Operation Requirements: Think about the level of gentleness required in handling your materials. Continuous elevators offer a smoother operation, which is crucial for delicate materials.


Both Continuous and Positive Discharge Bucket Elevator Systems have their place in the material handling industry. By understanding the key features, applications, and considerations for each type, you can make an informed decision that meets the needs of your operation. Whether you’re dealing with delicate food products or tough mining materials, there’s a bucket elevator system designed to handle your specific challenges efficiently and effectively.
