Crusher bucket for excavator is a heavy‑duty hydraulic excavator crusher attachment designed to mount directly onto standard excavator arms. Instead of transporting raw debris to distant crushing facilities, this robust accessory completes crushing work right at your job site. Built for demolition, quarrying, and construction renovation projects, it processes hard bulk materials without requiring extra standalone crushing machinery. Operators control all crushing functions via the excavator’s native hydraulic system, enabling seamless switching between digging, loading, and crushing tasks.

How Does the Excavator Crusher Bucket Work?
The operating mechanism of the crusher bucket for excavator relies on heavy-duty hydraulic jaw crushing principles powered directly by the carrier excavator’s auxiliary hydraulic circuit:
- Material Intake: The operator uses the unit like a standard bucket to scoop up reinforced concrete, demolition debris, natural stone, etc.
- Hydraulic Compression: High-torque hydraulic motors drive an eccentric shaft that moves a dynamic jaw plate against a fixed jaw plate with massive mechanical force.
- Size Reduction & Discharge: The material is crushed until it reaches the targeted particle size, whereupon gravity pulls the processed aggregate through the bottom discharge opening.
- Because the hydraulic pressure operates consistently at 25 MPa, the crushing mechanism delivers powerful compression without overloading or bogging down the excavator’s primary hydraulic power distribution.
What Materials Can the Excavator Crusher Attachment Process?
A crusher bucket for excavator is remarkably versatile. It handles:
- Demolition concrete and rubble – separating rebar is not required; the bucket crushes concrete while steel reinforcement typically passes through or can be easily removed afterward.
- Natural stone and rock – granite, basalt, limestone, and sandstone up to medium hardness.
- Asphalt slabs – ideal for road repair projects where reclaimed asphalt can be reused as base material.
- Brick and masonry waste – turning old structures into usable fill or sub-base.
- Mine overburden and quarry scalpings – reducing oversize material for further processing.
Eight Advantages Backed by Machine Specifications
- Massive Output Capacity Range
With bucket capacities ranging from 0.35 m³ on smaller models up to 0.8 m³ on heavy-duty units, contractors can select a unit optimized for their specific workflow and material throughput needs. - Optimized Hydraulic Efficiency
Operating at a standard working pressure of 25 MPa, the crusher bucket for excavator maximizes energy transfer. With hydraulic flow rate demands spanning from 90 L/min to 235 L/min across models, it pairs effortlessly with medium to heavy excavator lines. - Generous Material Feed Mouths
Inlet dimensions starting from 550×450 mm on compact units up to 950×500 mm on heavy-duty models prevent material bridging and allow large concrete pieces to enter smoothly. - Precise & Adjustable Output Sizing
The discharge setting is fully adjustable between 15 mm and 120 mm. This wide output size range enables operators to produce fine base layers or coarse backfill with a single equipment setup. - High-Strength Wear-Resistant Jaw Plates
Built with specialized high-manganese steel alloys, the internal fixed and dynamic jaws offer extended service life under continuous impact and abrasive rock conditions. - Robust Structural Build
Weighing between 1,500 kg and 4,000 kg, the reinforced structural body ensures maximum stability and durability under heavy continuous loads without stressing the excavator boom. - Simple Quick-Coupler Compatibility
Designed with standardized mounting geometries, the bucket hooks up to standard mechanical or hydraulic quick-couplers for fast, safe jobsite installation. - Minimal Operational Maintenance
Featuring centralized lubrication points and easily replaceable wear plates, routine daily maintenance is streamlined to maintain maximum jobsite uptime.
Model Selection Guide: Matching Equipment to Excavator Size
Selecting the correct crusher bucket for excavator setups depends primarily on carrier weight capacity and available auxiliary hydraulic flow. Here are some tips:
Small to Mid-Sized Projects (10–20T carriers): The YG-P15 is optimal for urban utility work, residential demolition, and tight space operations requiring a compact 1,500 kg unit.
General Construction & Demolition (20–30T carriers): The YG-P25 serves as the industry workhorse, delivering a 0.7 m³ capacity and a generous 750×500 mm inlet for mid-range excavators.
Heavy Mining, Quarrying & Large Civil Works (30–40T carriers): The YG-P35 delivers maximum throughput with its 0.8 m³ volume, 950×500 mm feed opening, and 235 L/min flow rate requirement.

Versatile Application Scenarios of the Crusher Bucket for Excavator
Urban Demolition & Building Renewal: Crushing concrete slabs and brick masonry right at the site boundary to create aggregate for immediate trench backfilling.
Road Construction & Maintenance: On-site processing of removed asphalt and concrete pavement for reusable road sub-base material.
Quarrying & Mining Works: Secondary crushing of oversize boulders at the quarry face without moving heavy machinery.
Pipeline & Trench Backfilling: Producing fine, uniform aggregate directly beside trenches to protect buried utility pipes.
Waste Recycling & Land Clearing: Processing environmental rock, stone, and demolition debris into sustainable construction products.
