A digger screening bucket turns your excavator into a mobile screening plant. Instead of hauling material off-site to be screened, the excavator scoops, screens, and separates right where the material sits. Fines pass through the mesh. Oversize stays in the bucket. The operator processes material on the spot, loads the screened product into trucks, and moves on to the next pile.
The YG series digger screening bucket offers six models covering excavators from 1.5 to 38 tons, with operating flow from 20 to 150 L/min and self-weights from 158kg to 2430kg. Every model features a rotating trommel design that handles both dry and wet materials, with interchangeable mesh screens from 10×10mm to 80×80mm.

Rotary Screening Bucket vs. Vibrating Screening Bucket
Screening buckets come in two main types: rotary (trommel) and vibrating. The YG series uses a rotary design, which offers distinct advantages for certain applications.
Rotary screening buckets use a rotating drum lined with mesh. Material enters the drum, and the rotation tumbles it against the screen surface, forcing fines through the openings while retaining oversize. The tumbling action breaks up clumps and keeps screen openings clear, even on wet or sticky material. This design is fully sealed and can operate underwater—a key advantage for river dredging and wet material processing.
Vibrating screening buckets use high-frequency vibration to shake material through the mesh. They are faster on dry, free-flowing materials but struggle with wet or sticky material that clogs the mesh.
The rotary advantage: The YG series rotating screening bucket handles both dry and wet materials. The rotating drum design prevents clogging, and the sealed construction allows underwater operation. For demolition sites with mixed debris, river dredging with wet sediment, or topsoil screening with moisture content, the rotary design is the more versatile choice.
The vibrating advantage: Vibrating screening buckets can achieve higher throughput on dry, consistent materials. But they cannot operate underwater and struggle with sticky materials.
The choice: For most demolition, construction, and landscaping applications, the rotary screening bucket offers greater versatility across a wider range of material conditions.
How to Choose the Right Digger Screening Bucket Mesh Size?
The YG series digger screening bucket uses interchangeable screen plates with mesh sizes from 10×10mm to 80×80mm. The right mesh size depends on the material and the required end product.
- 10-20mm mesh produces fine aggregate suitable for sand, topsoil, and fine backfill. This mesh size is commonly used in landscaping, pipe bedding, and concrete sand production.
- 20-40mm mesh produces medium aggregate suitable for drainage materials, subbase, and general construction fill. This is the most common mesh range for construction applications.
- 40-80mm mesh produces coarse aggregate suitable for road base, riprap, and heavy drainage applications. Larger mesh sizes are used when the goal is to separate oversize debris from usable material.
The practical rule: Choose the mesh size that matches the required end product. Screening to a finer size than necessary reduces throughput. Screening to a coarser size than necessary leaves unacceptable material in the product.
Changing mesh sizes: The screen plates are designed for quick replacement. The operator can change mesh sizes on site in minutes, adapting to different material requirements without returning to the workshop.
Material Types the YG Digger Screening Bucket Can Handle
The YG series excavator screening bucket is designed for a wide range of materials.
- Topsoil and compost. The bucket removes rocks, roots, and debris from topsoil, producing clean material for landscaping and planting. The rotating drum design handles the moisture content common in topsoil without clogging.
- Sand and gravel. Aggregate production is one of the primary applications. The mini excavator screening bucket separates sand from gravel, producing graded material for concrete, asphalt, and drainage.
- Demolition waste. Concrete rubble, brick, and mixed demolition debris are screened on site. The bucket separates usable aggregate from rebar and oversize debris, reducing disposal costs and creating a reusable product.
- River dredging materials. The sealed, waterproof design allows underwater operation. The bucket screens sand and gravel from riverbeds, lakes, and dredging sites.
- Mining and quarry materials. The bucket screens crushed rock and ore at the quarry face, producing graded material without hauling to a fixed plant.
- Coal and industrial minerals. The mini excavator screening bucket separates fine coal from oversize, improving product quality and reducing waste.
The practical advantage: One bucket handles multiple material types. Changing the screen mesh adapts the bucket to different materials and product specifications.
