What Is a Bucket Crusher for Excavator?
A bucket crusher for excavator is a hydraulic attachment that mounts onto a standard excavator arm. Two counter-rotating shafts inside the steel bucket grab and crush hard materials as the machine scoops. The crushed output falls through an adjustable grid at the bottom. You can control the output size by changing the gap between the grid bars. Most operators set the output between 15 mm and 200 mm depending on the project need.
This tool differs significantly from a standalone jaw crusher or cone crusher. A fixed crusher requires a dedicated machine, a power source, and a separate loader. In contrast, the excavator crusher attachment turns your existing machine into a mobile crushing unit. That combination lowers equipment rental costs and removes the need for extra operators. Furthermore, the crushed material can be recycled directly on-site as fill or subbase, which reduces both waste and material purchase costs.


Key Applications of Rock Crusher Bucket for Excavator
1. Construction and Demolition
Construction sites generate large volumes of broken concrete, brick, and rubble. Transporting this debris to an off-site facility is expensive and slow. The rock crusher bucket for excavator breaks this material on the spot. Workers can then reuse the crushed aggregate as backfill or sub-base. This approach saves significant hauling costs on most demolition projects and keeps the site clean throughout the work.
2. Quarrying and Small-Scale Mining
Quarry operations often need secondary crushing after blasting. This tool handles this step efficiently without additional equipment. It processes limestone, granite, and basalt to a usable size range. Smaller quarry operators particularly benefit because they avoid investing in a separate crushing plant entirely.
3. Road Construction and Maintenance
Road crews use this attachment to break up old asphalt and concrete pavements. The crushed material goes back into the road base immediately. This on-site recycling speeds up project completion. In addition, it reduces the number of dump truck trips needed, which lowers both fuel costs and road wear over time.
4. Land Clearing and Site Preparation
Developers often encounter buried rocks, concrete foundations, or mixed debris during site preparation. This attachment breaks through these obstacles quickly. Operators clear and process the material in a single pass. As a result, grading and compaction work can begin sooner, which keeps the project schedule on track.
5. River and Coastal Projects
Waterway and coastal projects involve rocky beds and natural stone formations. The excavator crusher processes this material without the need for additional machinery. Teams working on jetties, breakwaters, or riverbeds find this tool especially practical because access for large standalone crushing equipment is often very limited.
Why Choose YG Excavator Rock Crusher Bucket?
1. Wide Model Range for All Excavator Sizes
YG offers 8 standard models from YG-1 to YG-8. These models fit excavators from 8 tons up to over 75 tons. Whether you run a small urban demolition crew or a large quarry operation, a suitable model is available. You do not need to modify your existing excavator to use our bucket, which saves time and avoids extra engineering costs.
2. High Crushing Output
The YG-8 model reaches a maximum production rate of 120 m3 per hour. Even the entry-level YG-1 produces up to 10 m3 per hour. These output rates keep projects moving forward without bottlenecks at the crushing stage. The dual-shaft design maintains consistent throughput even with irregular-shaped material fed into the bucket.
3. Adjustable Output Size
Each model comes with an adjustable output grid. For example, the YG-3 allows output settings from 15 mm to 130 mm. Operators simply adjust the grid gap to match the required aggregate size on the day. This flexibility makes the same bucket suitable for multiple project types without purchasing extra tooling or attachments.
4. Heavy-Duty Wear-Resistant Construction
YG uses high-manganese steel for the crushing shafts and internal wear plates. These materials handle abrasive rock and concrete over long operating periods without frequent replacement. Additionally, the wear parts use a modular design for fast field replacement. Maintenance downtime stays short, which keeps productivity high even on the most demanding job sites.
5. Universal Compatibility and Quick Installation
The bucket uses a standard pin-type quick coupler system. It connects to most excavator models without custom adapters. The hydraulic lines connect to the machine’s auxiliary circuit in minutes. As a result, operators can switch between the crusher bucket and other attachments quickly throughout the workday without losing production time.
6. Factory-Direct Pricing and Global Supply
YG Machinery supplies this attachment directly from our production facility. There are no middlemen involved, so pricing stays competitive for all order sizes. We support OEM customization for clients with specific size or bracket requirements. Our logistics team ships to customers worldwide and our technical team provides support after every delivery.

FAQ About Bucket Crusher for Excavator
YG offers models for excavators from 8 tons to over 75 tons. The YG-1 suits 8 to 12 ton machines, while the YG-8 serves excavators above 75 tons. Refer to the carrier weight row in the specification table above to find your matching model quickly.
It handles concrete, limestone, granite, basalt, brick, and mixed demolition debris effectively. The dual-shaft design manages irregular shapes well. However, heavily steel-reinforced concrete may require pre-cutting before the bucket can process it cleanly.
You adjust the grid gap at the bottom of the bucket to change the output. A narrower gap produces finer material. A wider gap allows larger pieces through. Most YG models support adjustments between 15 mm and 200 mm depending on the specific model selected.
Lifespan depends on the hardness and abrasiveness of the material being crushed. For standard concrete crushing, the shafts and wear plates typically last several hundred operating hours. YG supplies replacement wear parts and offers guidance on recommended inspection and replacement intervals.
