Australia boasts one of the world’s leading mining and infrastructure markets. Excavator sales rose 17% year-on-year in Q1 2026. As construction sites increasingly demand on-site material reuse and reduced haulage, more contractors equip their excavators with screening attachments. Thanks to its reliable hydraulic drive system and flexible customisable screen openings, the YG rock screening bucket has been deployed at multiple construction sites across Australia.

Case 1: Quarry in Queensland – Turning Waste into Sellable Products
Client Background
The client operates a medium-sized quarry in Queensland, producing graded crushed stone and road base materials for construction. Blasting generates mixed waste stockpiled on-site, containing oversized rocks, clay-laden fines and irregular fragments. These piles occupy valuable space and incur high disposal costs.
Client Requirements
The client evaluated static screening plants, yet ruled them out due to high capital investment, long installation lead times and lack of mobility. They stated clearly: “We need equipment that mounts directly onto our existing excavator. No extra machinery purchase, just on-site screening.” They required a rock screening bucket capable of processing both dry materials and damp feed during wet seasons.
YG Solution
Based on the client’s CAT 336 excavator and material characteristics, YG’s engineering team recommended the YGGTS-20 rock screening bucket. This model fits 25–35 ton excavators with a 2.0m³ bucket capacity and 150L/min recommended flow. To separate stones over 30mm from fine material, YG customised 35mm screen mesh. The aperture delivers efficient separation between large rock and clay fines while balancing throughput and screening accuracy. High wear-resistant steel was adopted for the mesh to extend service life under hard rock conditions.
Project Process
YG supplied detailed hydraulic matching calculations and installation plans. The client’s main concern was ease of mesh replacement. YG engineers provided remote video guidance demonstrating full screen changeover within 15 minutes. After comparing two local Australian suppliers, the client selected YG, commenting: “YG delivers the best value for the same specification, and custom screen sizes fully meet our particle requirements.”
Operational Results
After commissioning, the quarry processed all accumulated mixed waste stockpiles with the equipment. The rock screening bucket handles roughly 150 tonnes per day. Oversized rock (> 30 mm) re-enters the supply chain for sale, while fines (< 30 mm) are reused for internal access roads and site rehabilitation. The quarry gains approximately AUD 12,000 extra revenue monthly. Meanwhile, truck haulage expenses for waste removal are reduced. With each truck trip costing AUD 200 and 60 fewer trips each month, transport savings alone reach AUD 12,000 per month.
Case 2: Western Australian Mine – Pre-Screening to Boost Productivity
Client Background
The client is an iron ore mining contractor in Western Australia, providing overburden removal and ore pre-processing services for a major mining company. The site is remote, resulting in extremely high transport costs. Any solution requiring off-site material processing is uneconomical.
Client Requirements
The contractor’s core challenge: stripped overburden and weathered fractured rock carry large volumes of fines and clay. Direct feeding into the crushing plant triggers frequent blockages, accelerates jaw plate wear and cuts production capacity by around 30%. They needed screening attachments for excavators to complete pre-screening ahead of crushing and remove fines and contaminants.
YG Solution
YG recommended the YGGTS-24 unit, suitable for 30–40 ton excavators with a 2.4 m³ bucket capacity. This model was fitted with 20mm mesh specifically to separate fines from iron ore overburden. YG also offered heavy-duty reinforced configuration, with key components built from Hardox wear plate to withstand highly abrasive iron ore at Western Australian mine sites.
Project Process
Using the client’s Caterpillar 349 excavator specifications and hydraulic parameters, YG engineers remotely completed flow and pressure matching calculations. Initially, the client doubted the performance of a rotary screening bucket on sticky iron-rich overburden. YG shared field footage from similar mine projects, showing continuous operation for hours on high-moisture laterite iron ore with minimal screen blockages. The video resolved the client’s concerns. All negotiations, contract signing and payment were completed online. YG finished production and shipment within 4 weeks, delivering bilingual English-Chinese installation manuals and operation & maintenance video tutorials together with the unit.
Operational Results
Once deployed, the digger screening bucket performed excellently on overburden removal. It processes around 80 tonnes hourly, effectively separating fines and clay below 20mm. Pre-screening greatly improves the purity of feed entering the crusher. Crusher blockage frequency dropped by roughly 70%, and jaw plate service life extended from 3 months to 5 months. The contractor estimates annual maintenance savings on crushing equipment of approximately AUD 30,000. Moreover, separated fines are reused for haul road construction and tailings capping, eliminating costs for imported fill material.
