A rotary screening bucket turns your excavator into a mobile material separator. You can screen rock, soil, and demolition debris right on site. This helps you skip costly trucking and stationary plants. YG Machinery designs rotary screening buckets for excavators from 1.5 to 38 tons. You get a reliable attachment that boosts your project speed. Read on to see how this excavator screening attachment fits your workflow.
Why Your Project Needs a Rotary Screening Bucket?
Save Time on Material Processing
On-site screening removes waiting time. You load the bucket and start separating material immediately. There is no need to haul raw material to a fixed screen. This shortens project timelines and keeps the crew moving.
Reduce Operating Costs
A rotary screening bucket cuts fuel, transport, and labor expenses. One machine does the digging and the screening. You avoid renting extra equipment or hiring more operators. Over a few months, the savings add up quickly.
Improve On-Site Efficiency
Clean material goes directly back into the trench or stockpile. You waste less space and time handling debris. Projects stay organized, and rework drops noticeably.

What Is a Rotary Screening Bucket?
A rotary screening bucket is a drum-style attachment that separates material using the excavator’s hydraulic power. It catches large stones and debris inside the drum while fine material passes through the mesh.
Main Structure
- Mounting bracket: connects the bucket to the excavator arm securely.
- Hydraulic motor: drives the rotating drum with consistent torque.
- Screening drum: built with replaceable mesh panels of various sizes.
- Cleaning system: self-cleaning brushes prevent clogging during operation.
How It Works
- The operator scoops material into the bucket.
- The hydraulic motor starts spinning the drum.
- Fines fall through the mesh and land directly on the ground.
- Oversized rocks and waste stay inside the drum.
- When the drum is full, the operator tilts and dumps the reject material.
Advantages of a Rock Screening Bucket For Excavator
On-Site Versatility
A rock screening bucket for excavator handles different materials. You can separate soil, gravel, crushed rock, and demolition waste without switching tools. This flexibility makes it a smart choice for contractors who take on varied jobs.
Low Maintenance
Few moving parts mean less wear. The drum bearings and hydraulic motor need only routine greasing. Operators can check and replace mesh panels in minutes, so downtime stays minimal.
High Productivity
Compared to manual sorting or stationary screens, the attachment keeps material flowing continuously. One operator manages both digging and screening, which increases daily output.
Rotary Screening Bucket Application Scenarios
1.Pipeline Backfilling:Clean, screened soil goes right back around pipes. You avoid using contaminated fill that could damage infrastructure.
2.Landscaping and Soil Preparation:Separate rocks and roots from topsoil to create fine planting beds. The bucket works in parks, golf courses, and residential projects.
3.Demolition Waste Recycling:Crush and screen concrete, brick, and asphalt debris on site. You reclaim valuable aggregate and reduce dumping fees.
4.Quarry and Mining:Pre-screen raw material before it reaches the crusher. Fine material bypasses unnecessary processing, saving energy and equipment wear.
Rotary Screening Bucket vs. Traditional Screening Equipment
| Feature | Rotary Screening Bucket | Traditional Screeners |
| Mobility | Mounts directly on excavator; moves with the machine | Stationary or needs a loader for feeding |
| Setup Time | Under 5 minutes | Often 1–2 hours for assembly and positioning |
| Cost Efficiency | Lower fuel and transport costs | Higher operational and hauling expenses |
| Screening Speed | 3X faster for mixed material | Slower due to extra material handling steps |
| Maintenance | Simple greasing and mesh swap | Multiple motors, belts, and screens to service |

FAQ About Rotary Screening Buckets
It handles rock, soil, sand, gravel, mixed demolition debris, and crushed concrete. You can also screen compost and biomass in lighter applications. The mesh size determines the maximum particle size that passes through.
First, check your excavator’s operating weight and hydraulic flow. Then, match these numbers with our parameter table above. For example, a 20-ton excavator fits the YG016 model. Our team can also recommend the best model for your jobsite.
Yes, the attachment works in damp soil and moderate moisture. Very sticky or heavy clay may slow the drum and reduce output. For consistent results, screen material with lower water content or choose a larger mesh.
Absolutely. We offer interchangeable mesh drums with various hole diameters. You can swap them to produce different aggregate sizes for base rock, drainage gravel, or sand.
Inspect the drum, bearings, and hydraulic connections every 50 working hours. Apply grease regularly and replace worn mesh panels as needed. Routine checks keep the attachment running smoothly for years.
