Product Introduction
A Hydraulic rotary screening bucket for excavator is designed to sort and separate materials directly at the job site. Instead of moving soil, gravel, or mixed debris to a separate screening machine, the rotating drum does the separation while mounted on the excavator. Fine material passes through the screen openings, while larger stones, roots, concrete pieces, or other oversized material remain in the bucket. This makes it a practical attachment for contractors who need flexible material processing without adding another machine to the job.

Product Features
Hydraulic rotary drum: The internal drum rotates continuously to agitate the loaded material and improve separation.
Replaceable screens: Different screen openings can be fitted for different material sizes, reducing the need to use a separate attachment for every job.
Heavy-duty construction: Wear-resistant steel is used in key working areas to handle abrasive materials and repeated loading.
Excavator-powered operation: The attachment uses the excavator's hydraulic system, so no standalone screening plant is required.
Flexible configuration: Bucket capacity, screen size, mounting dimensions, and hydraulic configuration can be matched to the excavator and working conditions.
Product Applications
This bucket is suitable for topsoil screening, gravel separation, sand classification, compost processing, trench backfilling, landscaping, demolition waste sorting, and material recycling. It can also be used for preparing reusable soil and aggregate on construction sites.
For example, a contractor excavating a trench may screen out stones from the excavated soil and reuse the finer material for backfilling. In landscaping work, the same attachment can help separate roots, rocks, and coarse debris from topsoil before final placement.
Key Advantages
The main benefit of a Hydraulic rotary screening bucket for excavator is that screening can take place where the material is already being handled. This can reduce additional hauling, secondary loading, and dependence on fixed screening equipment.
The rotating design also helps break up loose clumps while the material moves through the drum. With interchangeable screen sizes, operators can adjust the attachment to different separation requirements instead of relying on one fixed opening. For contractors working across several sites, this flexibility can be more useful than a single-purpose bucket.
FAQ
Q: 1. What excavators can use this screening bucket?
A: Models are available for different excavator classes, commonly covering approximately 5–40 tons. The correct model depends on machine weight, hydraulic flow, lifting capacity, and mounting dimensions.
Q: 2. What materials can it screen?
A: Typical materials include soil, sand, gravel, stones, compost, topsoil, and selected demolition or recycling materials. Material size and moisture should be considered when choosing the screen opening.
Q: 3. Can the screen size be changed?
A: Yes. Replaceable screen panels are available with different openings, allowing the bucket to be configured for different separation requirements.
Q: 4. Does it require a separate power source?
A: No. The rotary drum is normally driven by the excavator's hydraulic system through a hydraulic motor, provided the machine meets the required flow and pressure specifications.
Q: 5. Can the bucket be customized?
A: Yes. Common customization options include bucket capacity, screen aperture, mounting bracket, hydraulic configuration, and wear-resistant components. The final configuration should be confirmed against the excavator and intended material before production.
