Crusher bucket for excavator is a hydraulic-powered excavator attachment designed to break down rock, concrete, brick, and other hard materials into graded aggregate. It connects to your excavator’s existing hydraulic system, using the machine’s hydraulic power to drive internal crushing jaws. Unlike stationary crushers that require permanent installation and extra transport trucks, the crusher bucket moves wherever your excavator goes. It can work in tight urban demolition sites, remote quarry locations, road repair zones, or land reclamation areas.

Advantages of the Excavator Crusher Bucket
One of the biggest benefits of the crusher bucket for excavator t design is the stable hydraulic working system. All three models run at a standard working pressure of 25MPa. This consistent operating pressure delivers steady crushing force without sudden pressure spikes that could damage your excavator’s hydraulic circuit. The hydraulic flow requirement varies by model to match the output of different excavators. YG-P15 requires 90L/min flow rate, YG-P25 needs 145L/min, and YG-P35 operates at 235L/min. When you match the flow rate correctly, the bucket maintains smooth jaw movement and keeps production stable during long shifts.
The crushing output size is adjustable between 15mm and 120mm across all three models. This adjustability is extremely useful for contractors who need different aggregate sizes for different projects. You can produce fine gravel for backfilling, medium aggregate for sub-base road layers, or coarser crushed material for landscaping. You do not need to change buckets or swap out liners to switch output sizes. The setting can be adjusted on-site in a short time, which saves valuable working hours.
Another key advantage is the optimized bucket inlet opening. The inlet size controls the maximum raw material you can feed into the crusher. YG-P15 comes with a 550*450mm inlet, YG-P25 uses a 750*500mm inlet, and YG-P35 features a 950*500mm inlet. Larger inlet openings accept bigger chunks of rock or broken concrete, reducing pre-breaking work before feeding material into the bucket. This directly improves your site productivity.
Robust overall construction is built into every unit. The total weight of the buckets ranges from 1500kg for the YG-P15, up to 3000kg for YG-P25 and 4000kg for YG-P35. The heavier frames on the larger models absorb heavy impact loads during crushing, reducing vibration transfer to your excavator arm. The welded steel structure uses wear-resistant steel plates around the crushing chamber, which extends service life when working with abrasive granite, basalt, and reinforced concrete.
Heavy-Duty Configuration Details of the Excavator Crushing Bucket
Wear Plates: Structural body reinforced with Hardox-equivalent abrasion-resistant steel along internal sidewalls.
Jaw Dies: Manganese-alloy tooth profiles optimized for balanced compression and shearing force.
Hydraulic System: Standard fitted with shock-absorption safety relief valves to suppress pressure spikes caused by uncrushable materials.
Grease Lubrication Ports: Centralized greasing points for main eccentric shaft bearings to simplify field maintenance.
Universal Mounting Adapter: Compatible with pin-on, quick coupler, or custom OEM excavator hitches.
How Does A Crusher Bucket for Excavator Work?
First, the excavator positions the bucket over piles of waste concrete or rock. The operator lowers the bucket and scoops raw material into the inlet chamber.
Once loaded, the excavator’s hydraulic oil flows into the crusher bucket’s hydraulic motor. The motor drives the moving jaw against the fixed jaw inside the chamber. Compressive force fractures the rock or concrete. Small enough crushed pieces fall through the adjustable outlet gap at the bottom of the bucket. Larger fragments stay inside the chamber and get crushed again until they pass through the gap.
After finishing one batch, the operator lifts and tilts the bucket to discharge the finished aggregate directly into a stockpile. The crushed material can be reused on-site for backfilling, road building, trench fill, or sold as reusable aggregate.
Since the crusher bucket for excavator runs fully off the host excavator’s hydraulics, no separate generator, power line, or extra fuel engine is needed. Mobility is a major benefit. You can move the crusher bucket around a large job site, from demolition zones to excavation areas, just by driving the excavator.
Common Application Scenarios of the Excavator Rock Crusher Bucket
Demolition projects are the most popular use case. When tearing down old buildings, foundations, and retaining walls, contractors can crush broken concrete on location. Instead of paying truck fees to haul rubble away and buying new aggregate for backfill, they recycle waste concrete right there. This cuts material and transport costs dramatically.
Quarry and stone excavation work also benefits. Small quarries use crusher buckets to pre-crush loose rock before transport. It reduces rock size so haul trucks can carry more material per trip.
Road construction and repair sites often use these attachments. Old asphalt, broken curb stone, and rock excavated during road grading can be crushed on-site to form road base material.
Pipeline and trench projects use crushed material for bedding around pipes. Instead of ordering pre-made gravel, crews crush local rock to get the exact aggregate size they need.
Model Differences and Performance Comparison
Choosing the correct crusher bucket for excavator depends mainly on your excavator tonnage and required processing volume.
YG-P15 is built for 10-ton to 20-ton excavators. It has a bucket capacity of 0.35 m³, inlet dimension 550*450 mm, and a total weight of 1500 kg. The required working flow rate is 90 L/min. This lighter model suits smaller job sites, urban demolition projects with limited space, and contractors running mid-size excavators. It is easier to transport between job sites and places less strain on smaller excavator arms.
YG-P25 fits 20-ton to 30-ton excavators. Its capacity reaches 0.7 m³ with an inlet size 750*500 mm, weight 3000 kg, requiring 145 L/min flow. This model balances processing speed and machine weight, and it is the most popular choice for mid-sized demolition and road contractors. It handles higher daily crushing volumes while remaining compatible with widely used 20-30T excavators.
YG-P35 matches 30-ton to 40-ton heavy excavators. Bucket capacity is 0.8 m³, inlet size 950*500 mm, weight is 4000 kg, with a required flow rate of 235 L/min. This heavy-duty option targets large demolition sites and quarries with high daily material throughput. It accepts larger rock chunks and sustains continuous long-hour crushing operations.
