OverviewA crusher bucket is an excavator-mounted attachment that converts site rubble, concrete and raw stone into reusable base material on location. Proper model selection reduces jams, maximizes aggregate output, lowers off-site hauling and decreases project duration. Field studies show appropriate use can cut waste transport costs by around 60%.
Field Tips- Do not overload the bucket throat in one scoop: leave roughly one-third of the throat clear so the jaws can bite and pull material efficiently.
- When processing rebar-laden slab, install an iron separator magnet under the discharge chute to extract steel scrap automatically.
- Wash mud from under the jaw plates with a power washer every evening to prevent dried dirt loading the hydraulic motor.
- If output rock size becomes too large, flip reversible jaw plates to extend wear-part service life.
How to Match a Crusher Bucket to Excavator Size and Flow SpecsSelect a bucket that matches carrier weight, auxiliary oil flow and system pressure. Typical guidance:
- Medium Excavators (12–20 Tons): Use a mid-size bucket (0.6–0.8 m³). Typical auxiliary flow: 120–160 L/min for utility teardowns and road work.
- Heavy Excavators (20–35 Tons): Choose heavy units (0.9–1.2 m³). Typical flow: 180–240 L/min with adjustable output gap ranges (e.g., 15–120 mm).
- Severe Mining Excavators (35+ Tons): Specify high-capacity units with high-manganese jaw plates for crushing tough quarry rock.
Typical Job Site Uses- Urban Demolition & Recycling: Crush concrete debris into 15–80 mm sub-base gravel on site to avoid hauling and reduce purchase of virgin material.
- Road Work & Reconstruction: Process excavated waste rock to backfill road beds directly along the route.
- Quarry & Pit Clean-ups: Turn tailings and secondary waste rock into clean, sellable crushed gravel.

Frequently Asked Questions (Q&A)- Will rebar-laden concrete jam the jaws? Quality designs use straight jaw angles and reverse rotation functions. If rebar fits the output gap, steel tends to slide out with crushed rock; use magnets or separators where needed.
- How do operators adjust output aggregate size? Change the output gap by adding/removing shim plates behind the moving jaw plate; the operation normally takes minutes.
- How long do wear-resistant jaw plates last? High-manganese alloy castings typically provide 800–1,200 operating hours on standard concrete work; reversible plates can double service life.
Case Summary (illustrative)An example field case: a heavy-duty YG-series crusher bucket on a 24-ton machine reduced off-site hauling fees by over 50%, supplied crushed aggregate for new foundation beds, and shortened the overall schedule.
