Excavator Rotary Screening Bucket | Rotating Screen Bucket For Soil Gravel Mud Separation

The rotary screening bucket, also known as rotating sieve bucket, is a multifunctional excavator‑mounted attachment designed for on‑site material screening and separation. Powered by independent built‑in hydraulic motor, the cylindrical screening drum rotates steadily, so fine sand, mud and small‑size particles fall out through screen holes, while large‑size stones and debris stay inside the bucket. It completes feeding, screening and discharging in one step without extra screening equipment.

Our rotary screening bucket body adopts thick high‑strength wear‑resistant steel plate. The screening drum and mesh are made of wear‑resistant material to adapt to heavy‑load and harsh working conditions. The screen mesh is modular and replaceable. Customers can swap screens with different aperture sizes according to actual requirements for different separation standards. The hydraulic drive system is stable, effectively resisting impact from stones and bulk materials during continuous rotation.

All manufacturing workflows including plate blanking, flame cutting, stress relieving, welding, hydraulic component assembly and painting are completed in our own factory. Every rotary screening bucket will pass running test and hydraulic pressure inspection before delivery, to ensure smooth drum rotation without jamming or oil leakage.

This screening attachment can match various excavators from 6‑ton up to 30‑ton. We support custom screen aperture, bucket volume and connecting mounting dimensions. It greatly saves transportation and equipment investment cost for customers. It is very popular among earthwork contractors, river‑regulation projects, construction waste disposal yards and quarry operators.

✅ Hydraulic Rotary Drum Screening, One‑Step Separation Built‑in heavy‑duty hydraulic motor drives screening drum rotation. Realize on‑site separation of sand, soil, mud, gravel and stones. No need for extra large screening machines.

✅ Replaceable Modular Screen Mesh Screen panels are bolt‑on structure, easy to remove and replace. Multiple hole sizes optional. Change mesh quickly to adapt different working materials: soil, gravel, river sand, construction waste.

✅ Heavy‑Duty Wear‑Resistant Steel Construction Main bucket body uses thickened wear‑resistant steel plate. Reinforced welding on high‑stress positions. Resist impact of rocks and abrasive materials, extend whole‑service life.

✅ Stable Hydraulic Drive System High‑quality hydraulic motor and sealing components. Stable rotation performance, good leak‑proof performance, suitable for long‑time continuous site operation.

✅ Wide Compatibility & Easy Installation Directly install on excavator arm, connect hydraulic pipelines. Fit for multiple mainstream excavator brands. Custom mounting size for different machine tonnages. OEM service available.

✅ Multi‑Scene Flexible Working Capacity Work well for dry soil, gravel, and also adapt to wet mud, river silt. Suitable for land construction and water‑related dredging operations. Improve site working efficiency and reduce material transport cost.
