The excavator rock crusher bucket operates using your excavator’s existing hydraulic system, requiring no additional power sources or complex modifications. It features two heavy-duty jaw plates that move in a reciprocating motion to crush material between them. Material enters through the top opening, is crushed to your desired size, and exits through the adjustable bottom gap. The entire process is controlled directly from your excavator’s cab, giving you full precision over crushing speed and output. This simple yet robust design ensures reliable performance even in the harshest working conditions. It also seamlessly integrates with other excavator attachments, including drum cutters, pile drivers and rock saws, creating a complete on-site processing system that can handle every stage of a project from demolition to site preparation. YG offers a complete line of high-quality excavator crusher bucket for sale, with 8 models engineered to match every excavator size and project scale.

Application of YG Excavator Rock Crusher Bucket :
- Urban Infill Demolition: In dense city centers where space is limited and truck access is restricted, on-site crushing eliminates the need for multiple truck trips and reduces site congestion. It also allows contractors to work within tighter time windows, as they do not have to coordinate with hauling companies.
- Remote Road Construction: For road projects in rural or remote areas, transporting aggregate can cost more than the material itself. A rock crusher bucket for excavator processes local rock into road base on site, cutting material costs by up to 70%.
- Landscaping & Site Development: Break up boulders and bedrock during site preparation without blasting, then crush the resulting rock into decorative gravel or backfill material. This eliminates the need for separate drilling and blasting operations.
- Industrial Plant Demolition: Process reinforced concrete, brick and steel structures on site, separating recyclable materials as you work. This increases revenue from scrap metal sales and reduces waste disposal costs.
- Disaster Recovery: After natural disasters, quickly clear debris and crush it into usable material for emergency repairs and reconstruction, speeding up recovery efforts.
Excavator Rock Crusher Bucket Product Features
- Full Tonnage Matched Hydraulic System: Our 8-model lineup (YG-1 to YG-8) is calibrated to exact excavator hydraulic parameters, not generic standards. The YG-1 optimizes for 90l/min flow and 200bar pressure for 8-12 ton machines, while the flagship YG-8 handles 380l/min and 230bar for 75+ ton excavators. This perfect matching eliminates hydraulic overload, extends your excavator’s service life, and delivers 15% higher crushing efficiency than mismatched attachments.
- Model-Specific Adjustable Output Range: Each unit features a tool-free discharge gap adjustment system tailored to its capacity. Smaller models (YG-1 to YG-6) produce 15-145mm aggregate for residential backfill and landscaping, mid-range units (YG-7) deliver 40-150mm for road base, and the heavy-duty YG-8 crushes up to 200mm for large-scale quarry operations. You can switch between output sizes in 3 minutes to adapt to changing project requirements.
- Overbuilt Wear-Resistant Construction: All critical components use high-chromium alloy steel with thickness scaled to model size. The YG-1 weighs 0.75 tons for compact maneuverability, while the YG-8’s 10.5-ton reinforced frame handles the toughest hard rock crushing. Reversible jaw plates double their service life, and sealed bearings prevent dust ingress, reducing maintenance intervals by 40%.
- Optimized Feeding Opening Design: Opening dimensions range from 540×250mm (YG-1) to 1450×700mm (YG-8), perfectly matched to each excavator’s bucket capacity. This eliminates material spillage and reduces feeding cycles, directly contributing to our industry-leading production rates of 10-120m³/h across the lineup.
- Universal Quick-Change Compatibility: All models fit standard excavator quick couplers with no permanent modifications required. Installation takes less than 2 hours, and you can seamlessly switch between this attachment, drum cutters, pile drivers, and rock saws to turn a single excavator into a complete on-site processing fleet.
FAQ About Mini Excavator Crusher Bucket
A: Renting a mobile crushing plant typically costs $1,500-$3,000 per day plus fuel and operator wages. Our excavator rock crusher bucket costs a fraction of that, and you own it outright. Most contractors recoup their investment in 2-3 projects, after which every hour of use is pure profit.
A: No. Our mini excavator crusher buckets are precision-engineered to match the exact flow and pressure specifications of each excavator model. They include built-in pressure relief valves and flow control systems that protect your machine’s hydraulic system from damage.
A: It easily handles concrete, brick, limestone, granite, basalt and most natural rocks. It can also cut through rebar up to 25mm in diameter. You should avoid processing extremely hard materials like quartzite with high silica content, as this will accelerate wear on the jaw plates.
A: Production rates vary depending on material type and operator skill, but a typical YG-3 model will process 200-250 cubic meters per day. The largest YG-8 rock crusher bucket for excavator can process up to 900 cubic meters per day under ideal conditions.
A: Under normal use, the jaw plates will last 500-800 operating hours. Replacement jaw plates cost a fraction of the total attachment cost, and they can be changed on site in about 2 hours using basic tools.
