Screening Bucket is made of primary selection materials of various types for land reclamation and pre-selecting materials after demolition. The "gaps" in the grille are determined to suit the dimensions of the product to be selected. Ransun Skeleton Bucket use thick, high tensile round bar recessed deep into the torsion beam, lip, and cross bracings. This innovative design is far stronger, sifts material faster.
1. What is an excavator screening bucket?
An excavator screening bucket, also known as a sifting or sieving bucket, is a versatile hydraulic attachment that combines digging and material separation. It features a rotating drum or vibratory grids with interchangeable screens to sort materials (like soil, gravel, demolition waste) by size directly on-site.
2. How does a screening bucket work?
The bucket is attached to the excavator's arm. As the operator collects material, hydraulic power rotates the drum or vibrates the grids. Smaller particles fall through the screen mesh, while larger debris (rocks, roots, rubble) is retained inside the bucket for disposal or further processing.
3. What are the main applications?
Landscaping & Soil Preparation: Separate topsoil from stones and roots.
Demolition & Recycling: Sort clean aggregate from mixed construction debris.
Pipeline & Trenching: Backfill with screened, stone-free soil.
Agriculture & Forestry: Clear land and prepare seedbeds.
Mining & Quarrying: Pre-screen materials before crushing.
4. What are the key advantages over traditional methods?
Cost Efficiency: Eliminates need for separate screening plants and transport.
Time Savings: Screen and load in a single step, directly on-site.
Versatility: One attachment for digging, screening, and mixing.
Space Saving: Ideal for confined urban or remote job sites.
Material Reuse: Promotes recycling by separating valuable aggregates.
5. How do I choose the right screening bucket for my excavator?
Consider these factors:
Excavator Size: Match the bucket width and weight to your machine's class and hydraulic flow (measured in GPM or L/min).
Material Type: Specify screen mesh sizes based on the particles you need to separate (e.g., 1/4", 1/2", 2").
Job Requirements: Choose between drum-type (gentle, continuous screening) or vibratory-grid-type (high-speed, high-volume screening).
Attachment System: Ensure compatibility with your quick coupler
6. Can I use it with any excavator?
Most screening buckets are designed to be compatible with standard excavator quick-attach systems. However, you must verify:
Your machine's hydraulic flow and pressure meet the attachment's requirements.
Your excavator's weight class can safely support the bucket's operating weight.
7. What maintenance is required?
Daily: Inspect screens for damage or clogging; clean after use.
Weekly: Check hydraulic hoses and connections for leaks; lubricate bearings and rotating parts.
As Needed: Replace worn or damaged screen panels and teeth.
8. What screen sizes are available?
Screen mesh sizes typically range from 1/8" (3mm) to 4" (100mm). Custom sizes are often available. Common sizes include:
Fine screening: 1/4" or 1/2" for topsoil and sand.
General purpose: 3/4" to 1.5" for gravel and compost.
Heavy duty: 2" to 4" for demolition rubble and rocks.
9. Can it screen wet or sticky material?
Wet and clay-rich materials can clog screens. For such conditions:
Use larger mesh sizes or specially designed "self-cleaning" screens.
Consider a drum-type bucket with internal agitators.
Partially dry the material before screening if possible.
10. How is it different from a crusher bucket?
Screening Bucket: Separates materials by size; does not crush.
Crusher Bucket: Reduces the size of rocks and concrete into smaller aggregates.
