DW Type Bottomless Elevator Bucket Overview

DW type bottomless elevator bucket is designed for high-capacity conveying in agricultural applications. It uses a combination of multiple bottomless buckets with a base bucket to significantly increase system throughput.

Design Concept

Unlike conventional buckets with a closed bottom, DW buckets adopt a bottomless structure. Several bottomless buckets are installed closely together, with one bottom bucket positioned at the base to support material flow.

This configuration allows extremely small spacing between buckets, maximizing the number of buckets in operation.

Performance Advantage

By minimizing bucket installation spacing to nearly zero, DW bucket systems can dramatically increase conveying capacity. In many applications, overall capacity can be improved by approximately 20%.

  • Increased bucket density
  • Higher conveying capacity
  • Improved system efficiency
  • Optimized use of elevator space

Working Principle

Material is carried continuously through a series of bottomless buckets arranged closely together. The bottom bucket at the base ensures proper support and transfer, while the upper bottomless buckets maximize capacity and throughput.

Applications

DW type bottomless buckets are widely used in:

  • Grain conveying systems
  • Agricultural bulk material handling
  • High-output elevator systems
  • Applications requiring increased production capacity

Engineering Considerations

To achieve optimal performance, the following factors should be considered:

  • Elevator speed
  • Bucket arrangement and spacing
  • Material characteristics
  • System configuration

Comparison with DW Type

Compared with DW bottomless bucket systems:

  • DW type – maximizes capacity through minimal spacing
  • DG type – improves both loading and discharge efficiency with combined structure
