YG Machinery

In quarrying, infrastructure, and demolition projects, traditional stationary crushers face difficulties in relocation and high transportation costs, resulting in extremely low return on investment for small projects. The high cost of transporting stone back and forth also leads to significant waste of large quantities of waste stone. The excavator rock crusher bucket, also known as an excavator crushing bucket, hydraulic jaw crusher bucket, mobile crushing attachment, or excavator stone bucket, is a hydraulically driven crushing device mounted on the excavator’s boom. Its core function is to convert excavators into mobile crushers, crushing rocks, concrete blocks, and construction waste on-site. The crushed stone can be directly reused, significantly reducing raw material procurement and transportation costs.

YG, as a professional excavator attachment manufacturer, specializes in jaw crusher buckets suitable for all tonnage sizes, and also offers a full range of excavator attachments, including hydraulic breakers, log grapples, augers, and pile hammers, providing one-stop solutions to meet the diverse construction needs of engineering teams.

What Are the Core Functions of YG Excavator Crusher Buckets?

1. Full tonnage coverage, precisely matched to excavators from 8 to 75+ tons. YG offers eight models from YG-1 to YG-8, corresponding to excavators ranging from 8-ton mini excavators to mining excavators over 75 tons, with loading capacities from 0.15-2.30 m³ and a maximum output of 120 m³/h. Whether your excavator is a Komatsu PC200, Caterpillar 320, or Hitachi ZX870, you can find a matching crusher bucket.
2. Infinitely adjustable discharge particle size, precisely controlled from 15-200 mm. The discharge gap of each model can be flexibly adjusted according to project needs. The smaller models (YG-1/2) have an adjustment range of 15-60 mm, suitable for producing fine aggregates; the larger models (YG-7/8) can reach 40-200 mm, used for coarse crushing and embankment filling. Adjustment is simple and requires no special tools.
3. High manganese steel jaw plates, doubling the lifespan of forward and reverse rotation. The jaw plates are cast from Mn18Cr2 high-manganese wear-resistant alloy, with a hardness exceeding HB500. More importantly, the jaw plates can be flipped upside down and forwards/backwards, requiring replacement only after even wear. This doubles the lifespan compared to unidirectional use, significantly reducing the cost of wear parts.
4. Hydraulic direct drive + flywheel for stable load control, high efficiency and low vibration. The hydraulic motor directly drives the eccentric spindle via a splined shaft, with a built-in high-inertia flywheel providing stable torque output, resulting in a smooth and efficient crushing process. No belt drive is required, eliminating maintenance and the risk of belt slippage and breakage. Back pressure is controlled below 10 bar to prevent overheating of the excavator’s hydraulic system.
5. One-button hydraulic control, zero learning cost. The crusher bucket is controlled via the excavator’s foot pedal valve or pilot handle, operating in the same way as a hydraulic hammer, requiring no additional training for excavator operators. Installation requires only a pin connection and three hydraulic lines, completed in 15-30 minutes.

Combined with Other YG Attachments, The Crusher Bucket Offers Even Greater Value:

• Hydraulic shears + crusher bucket: Cuts reinforcing steel in reinforced concrete; the crusher bucket processes pure concrete, increasing efficiency by over 30%.
• Rock saw + crusher bucket: Saws oversized rocks into feedable sizes; the crusher bucket finely crushes them to the target particle size.
• Quick connector + crusher bucket: Quickly switches between different attachments on a single excavator, switching from excavation mode to crushing mode in 3 minutes.
• Vibratory tamping plate + crusher bucket: The crusher bucket produces aggregate, while the tamping plate compacts the base layer; one machine handles all road construction needs.
• Milling machine + crusher bucket: The milling machine excavates hard rock trenches, while the crusher bucket processes the excavated material; a highly efficient combination for pipeline engineering.

The investment in a set of attachments is far lower than purchasing multiple independent machines, while the operational flexibility is unmatched by individual machines.

In Which Fields Can Excavator Crusher Buckets Be Used?

1. Building Demolition and Waste Recycling: This is the most classic application of excavator crusher buckets. The demolition of old buildings generates large amounts of concrete blocks and bricks. Excavator crusher buckets crush these into recycled aggregate on-site, which can be directly used for backfilling new building foundations or paving temporary roads. The crushed material doesn’t leave the construction site, saving on dumpster rental and transportation costs.
2. Road Construction and Maintenance: During road expansion and resurfacing, excavated old asphalt and base rock need to be processed. Excavator crusher buckets crush the old material and use it directly as base material for new roads, eliminating the need to purchase new aggregate. Especially in mountainous road construction, rock crusher buckets for mini excavators process excavated rock, producing embankment fill on-site, reducing transportation distances from tens of kilometers to zero.
3. Mining and Quarrying: Large mines use fixed crushing stations to process the main ore body, but excavator crusher buckets are more economical for processing marginal ore bodies, scattered ore blocks, and backfill material from mined-out areas. The YG-6 to YG-8 models are compatible with 35-75 ton mining excavators, with a capacity of 53-120 m³/h, serving as auxiliary crushing equipment to reduce pressure on the main production line.
4. Pipeline and Trench Engineering: After excavating pipeline trenches in rocky areas, the excavated rock needs processing before it can be used as pipeline backfill. The crushing bucket crushes directly at the trench edge, and the crushed material is backfilled on-site, resulting in a compact and efficient process.
5. Municipal and Urban Renewal: In old city redevelopment projects, space is limited, making it difficult for large equipment to enter. Mini excavators equipped with mini excavator crusher buckets can operate between buildings, with significantly lower noise and vibration compared to hydraulic hammers, minimizing the impact on surrounding residents.
6. Agriculture and Land Consolidation: After clearing rocks and tree roots from farmland, the crushing bucket breaks the rocks into road-building gravel, eliminating the need for external assistance for farm road maintenance. This application is particularly popular in large ranches in Australia, New Zealand, and South America.
7. Water Conservancy Projects and River Regulation: Riverbank protection and embankment reinforcement require large quantities of crushed stone aggregate. The crushing bucket processes the excavated riverbed rocks to directly produce slope protection stones that meet the gradation requirements, reducing external purchases and transportation.

Case Studies of Chilean and Philippine Customers Using YG Excavator Attachments and Crusher Buckets

Case Study 1: Copper Mine Near Santiago, Chile – Crushing Buckets Eliminate Waste of Edge Ore

• Client Background: A medium-sized copper mining company located in the Andes Mountains, 80 kilometers north of Santiago. The main ore body is processed by a fixed crushing station, but loose ore blocks at the edges and top of the stope have long been uneconomical to process, resulting in approximately 3,000 tons of edge ore being discarded annually.
• Product Used: YG-6 crushing buckets, installed on a Caterpillar 349D (50-ton) excavator.
• Problem Solved: After purchasing the YG-6 crushing buckets, the excavator directly crushes loose ore blocks to below 80mm when operating at the stope edge. The crushed ore is then transported to the concentrator by dump trucks for grinding. The mobility of the crushing buckets allows the excavator to move freely between different working faces, unrestricted by fixed pipelines and foundations.
• Usage Results: The recovery rate of scrap ore increased from less than 20% to over 85%, recovering approximately 2,400 tons of copper ore annually. Based on local copper ore grade and beneficiation recovery rate, this translates to an annual increase in revenue of approximately $180,000. The equipment investment was recouped within 4 months.
• Customer Testimonial: “The YG crusher bucket has a large enough feed opening to directly feed ore blocks as small as half a meter square. The jaw plates only needed replacing after 8 months, making them much more durable than other brands we used before. Most importantly—we no longer have to watch scrap ore go to waste.” — Carlos M., Mine Equipment Supervisor

Case Study 2: Manila Old Town Redevelopment, Philippines—A Crushing Tool for Narrow Lanes

• Client Background: The Intramuros Historic District redevelopment project in Manila required the contractor to demolish old concrete buildings within 3-4 meter wide lanes and backfill the new foundations with the rubble. Large equipment could not access the site, and material transportation costs were extremely high.
• Product Used: YG-2 crusher bucket, installed on a Kubota KX080-3 (8-ton) mini excavator.
• Problem Solved: The mini excavator allows for flexible operation within tunnels, first crushing concrete slabs and walls, with the debris immediately used to fill the new foundation pit. All materials remain within the tunnel entrance, eliminating the need for dump trucks and transportation permits. The crusher bucket operates at significantly lower noise levels than hydraulic hammers, resulting in no complaints during construction in residential areas.
• Results: Project timeline shortened by 25%, transportation costs reduced by approximately $12,000/month, and an additional $5,000 bonus from the client for zero noise complaints. 100% of the crushed material is utilized on-site, with zero landfill.
• Customer Testimonial: “Previously, this kind of work required manual hammering, yielding only a few cubic meters of material per day. Now, with the mini excavator equipped with the YG crusher bucket, one person can do the work of five people in a day. No neighbors have complained about the noise either.” — Project Engineer Roberto D.
