The excavator crusher bucket is a hydraulic crushing attachment that can be directly mounted on various excavators. It requires no additional power equipment and is driven by the excavator’s own hydraulic system to crush, screen, and recycle hard materials such as concrete blocks, rocks, and construction waste on-site. It combines the “digging” and “crushing” functions of an excavator, significantly expanding its application range and becoming a core piece of equipment for cost reduction and efficiency improvement in engineering construction. With its flexibility, efficiency, and controllable costs, it has become an essential piece of equipment in mining, demolition, and road infrastructure projects. As a professional manufacturer of excavator crusher buckets, YG has focused deeply on this industry for years.

How the Excavator Crusher Bucket Works
The Excavator Crusher Bucket operates based on the combined action of hydraulic transmission and mechanical compression. It relies entirely on the excavator’s own hydraulic system for power, requiring no additional power input:
- Power Transmission: Mount the excavator crusher bucket on the excavator boom with a quick connector and connect it to the excavator’s hydraulic lines. The excavator’s hydraulic system supplies high-pressure power and delivers it to the internal hydraulic motor and eccentric shaft of the bucket.
- Crushing: The hydraulic motor drives the eccentric shaft to rotate, causing the moving jaw plate inside the bucket to reciprocate. This reciprocating motion creates a strong compressive and shearing force with the fixed jaw plate, gradually compressing and crushing hard materials (such as concrete and rock) entering the crushing chamber until the material reaches the preset particle size. The Excavator Concrete Crusher features an optimized jaw plate spacing specifically for concrete characteristics, allowing for precise control of the crushed particle size and preventing over-crushing.
- Screening and Discharge: The crushed material passes through a screening screen at the bottom of the bucket to separate particles that meet the required size. Larger, unqualified pieces remain in the crushing chamber until they are crushed to the required size and then discharged. The entire process requires no manual intervention and allows for continuous crushing operations. It is particularly suitable for small-scale operations using a mini digger crusher bucket, offering flexibility, efficiency, and labor savings.
Key Features and Advantages of Excavator Crusher Bucket
1. Versatile and Efficient
No additional fixed crushing equipment is required. Simply mount it on an excavator for integrated “digging, crushing, and removal” operations, significantly reducing equipment investment and site occupation. Operating efficiency is over 60% higher than traditional crushing methods. It can flexibly adapt to both large-scale batch crushing in large projects and precision operations in small projects, whether it’s conventional crushing or specialized excavator concrete crushing.
2. High Adaptability and Comprehensive Product Range
As a professional excavator crusher bucket manufacturer, YG’s products cover all scenarios and are compatible with various mainstream excavators ranging from 1.5 to 40 tons. They offer mini digger crusher buckets for small excavators, standard models for large excavators, and excavator concrete crushers specifically designed for concrete crushing. The discharge particle size can be flexibly adjusted between 20-120mm to meet different construction needs.
3. Energy Saving and Cost Controllable
Utilizing the excavator’s own hydraulic system, no additional power is required, reducing energy consumption by 40% compared to large stationary crushing equipment. Core components are made of high-strength wear-resistant steel, ensuring a long service life. Wear parts are universal and easily procured, resulting in low maintenance costs. The mini digger crusher bucket, in particular, offers low initial investment and quick return on investment, making it the preferred choice for small and medium-sized engineering companies.
4. Green and Environmentally Friendly, Safe and Reliable
On-site crushing eliminates the need for material transfer, reducing dust and noise pollution during transportation. With a simple dust removal device, dust-free operation is possible. No close contact with the crushing area is required during operation. Equipped with overload protection devices, it prevents equipment jamming and damage, ensuring a high level of operational safety.
5. Easy Operation and Quick Learning
No professional operators are required. Excavator drivers can operate the equipment after simple training. Equipment operation is integrated with excavator operation, eliminating the need for additional complex procedures. Both the standard model and the mini digger crusher bucket can be quickly put into operation, reducing training costs.
Excavator Crusher Bucket Common Problems and Solutions
As a professional excavator crusher bucket manufacturer, YG excavator crusher buckets have become the first choice for engineering companies due to their stable performance and comprehensive after-sales service. Their products cover standard models, mini digger crusher buckets, and excavator concrete crushers. Common problems are mostly concentrated during operation. Based on field construction experience, the following five types of high-frequency problems and practical solutions have been compiled to help users quickly troubleshoot and reduce downtime losses:
1. Decreased crushing efficiency and uneven output particle size
The core reasons are insufficient hydraulic pressure, severe jaw plate wear, or screen blockage.
Solutions: Check the excavator’s hydraulic system pressure to ensure it reaches the equipment’s rated pressure; regularly check the jaw plate wear and replace wear-resistant jaw plates in a timely manner; clean the material blocking the screen, especially for excavator concrete crushers, focusing on cleaning concrete residue to avoid affecting output efficiency.
2. Equipment jamming and malfunction
This is often caused by excessively large material particle size, overfeeding the crushing chamber, or eccentric shaft jamming, especially common in mini digger crusher bucket operations.
Solution: Stop operation, remove large pieces of material from the crushing chamber, strictly control the feed particle size within the equipment’s specified range; check the eccentric shaft for foreign objects obstructing it, add lubricating oil, and ensure smooth operation.
3. Hydraulic line leaks and abnormal noises
This is mainly caused by loose hydraulic line joints, aging seals, or insufficient hydraulic oil. This is a common problem with all excavator crusher attachments.
Solution: Tighten the line joints, replace aging seals; add hydraulic oil of the correct specifications, regularly check the hydraulic oil cleanliness to prevent impurities from entering the pipeline, and extend the equipment’s service life.
4. Jaw plate loosening or detachment
This is often caused by loose fixing bolts or improper jaw plate installation, especially in high-intensity crushing operations.
Solutions: 1. Regularly check the jaw plate fixing bolts and tighten them to the specified torque. If the jaw plate is misaligned, readjust the installation position to ensure a tight fit with the fixed jaw plate. Due to its small size, the mini digger crusher bucket requires extra attention to installation accuracy.
5. Excessive Equipment Vibration and Abnormal Noise
This is mainly caused by insecure equipment mounting, foreign objects inside the crushing chamber, or worn bearings.
Solutions: Re-inspect the quick connectors to ensure the Excavator Crusher Bucket is securely mounted; clean foreign objects from the crushing chamber; check bearing wear and replace worn bearings promptly; and implement vibration-damping measures to reduce noise pollution and meet green construction requirements.
