Description

Technical Parameters

Construction waste generated from home demolition, village and town renovation, and small-scale municipal repairs generally suffers from high transportation costs, cumbersome disposal procedures, and the inability to reuse waste on-site. Renting a large crusher is too expensive, and manual crushing is extremely inefficient, making it difficult for small-scale projects to cover costs. The mini excavator crusher bucket, also known as a mini jaw crusher bucket, mini excavator crushing bucket, on-site construction waste crushing bucket, or small hydraulic crushing bucket, is a hydraulic crushing attachment mounted on a mini excavator. Its core function is to transform an ordinary mini excavator into a small mobile crusher, directly crushing demolished concrete and bricks on-site, eliminating the need for loading and transportation, and significantly reducing waste disposal costs. One mini excavator can handle the entire process of demolition, crushing, and backfilling, making it an essential attachment for cost reduction and efficiency improvement in small-scale projects.

YG, as a professional excavator attachment manufacturer, specializes in hydraulic crusher buckets compatible with all tonnage sizes. The equipment has already been exported in batches to countries such as the Philippines, Vietnam, Mexico, South Africa, Indonesia, Kenya, and Thailand. It is widely applicable to small-scale demolition, rural infrastructure construction, and landscaping renovations, and is especially suitable for small to medium-sized construction projects with scattered workloads and limited space.

6 Key Features of YG Excavator Attachments - Crusher Bucket

Fully hydraulic direct drive for high crushing efficiency. The design uses a hydraulic motor to directly drive the eccentric shaft, reducing power loss and increasing transmission efficiency by approximately 15% compared to belt drives. The YG-1 model (compatible with 8-12 ton excavators) has a maximum capacity of 10 m³/h, equivalent to crushing approximately 15 tons of concrete waste per hour – more than enough for small projects.
Adjustable discharge particle size for multiple uses. By adjusting the number of shims under the jaw plates or the hydraulic adjustment mechanism, the discharge particle size can be freely controlled from 15mm to 60mm (standard models can reach 100-130mm). Adjust the size to larger for roadbed material and smaller for backfill fine material, handling multiple aggregate needs with one machine.
Flip-over jaw plates for double lifespan. Both the movable and fixed jaw plates are made of high-manganese steel (Mn13), which undergoes work hardening under impact, becoming harder with use. Furthermore, the upper and lower jaw plates are interchangeable, allowing one jaw plate to function as two, effectively doubling their lifespan and significantly reducing consumable costs.
Quick-change design, switch attachments in 5 minutes. Equipped with a standard excavator mount, it can be used with quick couplers, allowing the operator to switch between the crusher bucket and other attachments such as ordinary excavator buckets and hydraulic breakers from the cab, without manual bolt tightening. A new function can be switched in 5 minutes.
Sloping feed lip for faster material intake. The bucket opening features a sloped tongue design, facilitating the shoveling of material from the ground into the bucket. Loading efficiency is approximately 20% higher than a flat-mouth design, and it is less prone to damage to the bucket opening edge.
No jamming during full-load start-up. The optimized hydraulic system design ensures smooth start-up of the crusher even when the bucket is full of material-a crucial feature in actual operation, eliminating the hassle of repeatedly emptying and loosening material.

Frequently Asked Questions about YG's Excavator Rock Crusher Bucket

Q: Can it be installed on all brands of excavators?

A: Most mainstream excavators are compatible. It uses a universal quick-change interface; simply connect it to the hydraulic lines. For some niche models, a custom connector can be provided, without modifying the excavator itself.

Q: Can the output particle size be adjusted freely?

A: Yes, the output size can be controlled by adjusting the jaw plate gap. It can be freely adjusted within the 0- 50 mm range to meet different particle size requirements for backfilling, paving, and sand making.

Q: Can it crush concrete mixed with reinforcing steel?

A: Models with steel reinforcement protection can; it will automatically release pressure and discharge any steel reinforcement without damaging the equipment. For models without protection, it is recommended to remove large steel reinforcement first to avoid damaging the jaw plates.

Q: Is installation complicated? Does it require modification of the excavator's hydraulic system?

A: No, it's not complicated. Simply replace the existing bucket and connect it to the spare hydraulic lines. No modification to the excavator's hydraulic system is needed. An excavator operator can install it in 15 minutes by following a video tutorial.

Q: How often do the jaw plates need to be replaced?

A: Wear varies greatly depending on the material. In pure concrete conditions, it lasts approximately 800 hours, while in conditions containing sand and gravel, it lasts approximately 500 hours. This is considered normal consumable wear and can be replaced individually, resulting in low maintenance costs.
