Excavator Rock Crusher Bucket (Hydraulic Jaw Crusher Bucket) | Yantai Gaea

Excavator Rock Crusher Bucket (Hydraulic Jaw Crusher Bucket) by Yantai Gaea

Hero

Yantai Gaea offers a full range of excavator rock crusher buckets—hydraulically driven jaw crusher attachments that turn concrete, rocks and demolition debris into reusable aggregates right on the jobsite.

Mounted on any brand of excavator, our crusher bucket integrates crushing and output control into one compact, mobile process—helping contractors:

• crush and recycle materials on site

• reduce transportation and disposal costs

• achieve adjustable output sizes for different reuse needs

• work efficiently in quarries, demolition sites, road construction and recycling projects

Product Overview

An excavator rock crusher bucket is a portable, mobile crushing attachment installed on an excavator for on-site material processing. It is powered by the excavator's hydraulic system—no additional power source required.

Core components:

• Hydraulic motor — directly connected to the drive shaft for powerful and stable crushing performance

• Jaw plates (fixed jaw + moving jaw) — high-strength wear-resistant materials for long service life

• Adjustable discharge setting — output particle size can be adjusted according to project requirements

• Frame and housing — robust construction built for heavy-duty crushing conditions

Commonly crushed materials:

• rocks and natural stone (granite, limestone, basalt, etc.)

• concrete blocks and cement structures

• bricks and mixed demolition waste

• asphalt and construction debris

Two Installation & Feeding Methods

1) Forward Mounting (Direct Feed)

Inlet faces toward the operator — the excavator scoops material and crushes it in a self-feeding cycle.
Ideal for standard operations where material can be picked up directly by the carrier machine.

2) Reverse Mounting (External Feed)

Inlet faces outward — a smaller excavator or loader feeds material into the crusher bucket while it runs continuously.
This setup reduces self-loading time and allows the crusher bucket to operate without interruption, significantly improving overall throughput.

How It Works

The crusher bucket uses a jaw crushing mechanism driven by the excavator's hydraulic motor:

1. The hydraulic motor drives the eccentric shaft, causing the moving jaw to move up and down

2. When the moving jaw rises, the crushing chamber opens — material enters under gravity

3. When the moving jaw closes toward the fixed jaw — material is compressed, sheared and crushed

4. Crushed material exits through the adjustable discharge outlet

5. The cycle repeats continuously for efficient, high-throughput crushing

Key Benefits

• On-site crushing & recycling — process materials where they are, reduce transport and landfill costs

• High mobility & low setup cost — no fixed crushing station needed; simply mount and start working

• Adjustable output size — discharge setting can be changed to match your reuse requirements

• High crushing efficiency — continuous jaw crushing cycle delivers consistent productivity

• Durable jaw plates — high-strength wear-resistant materials built to handle abrasive rock and concrete

• Versatile compatibility — fits various excavator brands and sizes

• Environmentally friendly — on-site processing reduces waste and supports material circularity; optional water spray for dust suppression

Applications

• Quarrying & mining — secondary crushing of stone and ore

• Building demolition — recycle concrete, bricks and debris into reusable aggregates

• Road construction — crush excavated rock for roadbed filling and base layers

• Earthwork & civil engineering — onsite reduction for backfill, trenching and site leveling

• Municipal projects — material processing for pipeline laying, ditch excavation and urban renovation

• Recycling & waste management — transform demolition waste into reusable resources

Model Range & Technical Specifications

Yantai Gaea provides a complete range of excavator rock crusher buckets to match different excavator sizes and project requirements. Our models are classified by carrier excavator tonnage and crushing capacity.

How to Choose the Right Crusher Bucket

When selecting an excavator rock crusher bucket, consider:

• Excavator tonnage and hydraulic capacity — match the bucket model to your carrier machine

• Material type and hardness — rock, concrete, bricks, or mixed demolition waste

• Required output size — adjust discharge setting to meet your reuse or backfill needs

• Feeding method — forward mounting for self-feeding or reverse mounting for continuous external feeding

• Site conditions — space constraints, dust control needs, and production targets

FAQ

Can the crusher bucket be mounted on any excavator brand?

Yes. Yantai Gaea crusher buckets are designed as standard excavator attachments and can be configured for various excavator brands and models. We will verify compatibility based on your machine specifications.

What output sizes are available?

The discharge setting is adjustable. Depending on the model, output particle size typically ranges from 15 mm to 200 mm, allowing you to produce material suitable for backfilling, road base, or further processing.

How is forward mounting different from reverse mounting?

• Forward mounting: the inlet faces the operator — the excavator scoops and crushes on its own.

• Reverse mounting: the inlet faces outward — a second machine feeds material for continuous, higher-throughput crushing.

What maintenance is required?

• Regularly inspect jaw plates for wear and replace when needed

• Check hydraulic connections for leaks before each shift

• Avoid running the bucket empty (no-load impact) to prevent unnecessary wear

• Clean the bucket after use and store properly

Is a dust suppression system available?

Optional water spray systems can be configured to reduce dust on site where environmental or visibility requirements apply.
