Main Components of the Rock Crusher Bucket For Excavator
The bucket relies on several key parts to handle tough material.
- Jaw Plates: Fixed and movable jaws use Hardox steel. This material resists impact and gives long service life.
- Hydraulic Motor: It delivers high torque to drive the eccentric shaft.
- Eccentric Shaft: It turns hydraulic power into a strong crushing motion.
- Adjustable Discharge Outlet: You can change the output size from 15 mm up to 200 mm.
- Reversible Function: Jaw rotation clears blockages and keeps production steady.
Here is how the system works. Hydraulic oil flows from the excavator to the motor. The motor spins the eccentric shaft. The shaft moves the movable jaw. The jaw crushes rock against the fixed jaw. Crushed material drops through the discharge gap. If an uncrushable object enters the chamber, the overload system releases it. This process repeats rapidly. The result is a steady flow of sized material right behind the bucket.
Application Areas of the Excavator Crusher
The bucket performs well across many job sites. Below are common uses.
- Quarrying: Produce sized aggregate directly at the face. This cuts down on wheel loader and dump truck movements.
- Demolition and Concrete Recycling: Crush debris into reusable fill. You can separate rebar and recycle steel on site.
- Road Construction: Prepare base material for new roads or repair existing ones. The bucket handles both asphalt and rock.
- Trenching and Landscaping: Process excavated material into backfill. You create drainage gravel or decorative stone quickly.
- River Gravel Processing: Turn rounded stones into sharp-edged aggregate. This material works well for concrete and drainage layers.
In each case, the attachment helps you finish work faster. You also lower transport costs because material stays on site.
YG Crusher Attachment For Excavator Advantages
YG designs every bucket with productivity and durability as the top goals.
- High Torque Drive: The hydraulic motor provides steady, powerful force. It matches well with your excavator’s auxiliary system.
- Hardox Steel Construction: Key wear parts handle both impact and abrasion. You can reverse the jaw plates to use the other cutting edge.
- Quick Output Adjustment: Change the discharge gap fast with simple shim adjustment. This gives you full control over final product size.
- Built-In Overload Protection: The pressure relief system guards the bucket structure and your excavator. It reacts to unexpected loads immediately.
- Fast Installation: A standard quick-coupler interface makes mounting simple. Most operators connect the bucket within a few minutes.
These advantages combine to give you a reliable, long-lasting tool. You can trust it to perform job after job.
Excavator Rock Crusher Bucket FAQ
It is a jaw crusher attachment that mounts on an excavator. The unit breaks large rocks and concrete into smaller pieces. Your excavator’s hydraulics drive the crushing action directly on site.
Match the bucket model to your excavator’s operating weight and oil flow. The specification table shows recommended carrier weights for each model. For example, a 20-ton excavator pairs well with the YG-3 model. Always check pressure and flow ratings to ensure full performance.
Yes, it can crush concrete that contains rebar. Remove large steel sections before feeding. The crusher breaks the concrete and exposes the rebar. This separation makes steel recycling much easier.
You adjust the discharge gap using shims behind the toggle plate. A smaller gap produces finer material. A larger gap allows faster processing of coarser stone. The setting range varies by model from 15 mm to 200 mm.
It depends on the model and material hardness. For instance, the YG-6 can produce up to 53 cubic meters per hour in medium-hard rock. Jaw plate condition and proper setting also affect the rate.
