A rock screening bucket for excavator is a hydraulic attachment that turns your excavator into a mobile screening plant. It consists of a rotating cylindrical drum with perforated steel plates or mesh. The drum is driven by a hydraulic motor powered by your excavator’s auxiliary circuit.
You scoop material into the bucket using the excavator. The hydraulic motor spins the drum, separating material by size. Smaller particles fall through the screen openings into a pile below. Larger rocks and debris remain inside the drum. The bucket can be tilted to discharge oversize material where you want it.
The attachment is used for screening topsoil, compost, sand, gravel, demolition debris, and other materials. It is widely used in landscaping, construction, demolition, and site preparation.

How Does An Excavator Screening Bucket Work?
Step 1 – Load. Use the excavator to scoop material into the screening bucket. The bucket acts like a normal excavator bucket for loading.
Step 2 – Screen. Activate the auxiliary hydraulic circuit. The hydraulic motor spins the drum. As the drum rotates, smaller material falls through the screen openings. The fines form a pile beneath the bucket.
Step 3 – Discharge. When the oversize material is separated, tilt the bucket to dump the rocks and debris. The clean, screened material remains in a pile ready for use.
The process is continuous. You can screen load after load without moving the pile to a separate screening plant.
