Crushing & Screening BucketsJY-MT shaft screening series · Excavator attachment

Screening bucket

A hydraulically powered shaft screening bucket for processing soil and separating suitable material by size. Rotating rollers screen and mix material inside the bucket; this mechanism differs from a rotating screening drum.

Excavator classes: 18–45 t, model-specific
Bucket capacities: 1.2 / 1.7 / 2 m³
Hydraulic flow: 120–200 / 150–220 / 200–320 L/min

Product & applications

About the screening bucket

Features & benefits

Reversible roller motion

Hydraulic power turns the rollers forward and in reverse to work material inside the bucket.

Screening, mixing and stirring

The shaft arrangement separates eligible material while mixing and stirring the bucket contents.

Carbide-inlaid screening cutters

Carbide inlays protect the screening cutters against wear during material processing.

Wear-resistant structural steel

High-strength, wear-resistant steel supports the bucket structure during screening and mixing.

Hydraulic motor and valve block

The drive and valve block power the roller mechanism; compare the stated flow for each model.

**75 mm coarse-screen shaft layout**This manufacturer illustration shows the H-75 arrangement. Confirm the chosen gap and feed material separately from the bucket model dimensions.

**45 mm coarse-screen shaft layout**This illustration shows the narrower H-45 arrangement. It is a configuration comparison, not proof that every photographed bucket uses this gap.

Typical applications

Excavator shaft screening bucket releasing screened soil on a construction site — Shaft screening bucket separating soil at a work site

Soil and backfill preparationSeparate suitable finer soil from coarse pieces for backfill and site preparation.
Sand and aggregate separationSelect the shaft arrangement and opening for the feed material and required particle fraction.
Material mixingMix compatible soil and additives using the roller arrangement described in the manufacturer’s catalogue.

Installation requirements

Confirm the attachment fits your excavator

Before ordering, send the machine identification and the connection, power and working information relevant to this product.

Pin diameters and centre-to-centre distance — Pin-on interfaces only. Use the actual machine and attachment drawing.

Clear inside mounting width — Pin-on interfaces only. Use the actual machine and attachment drawing.

Excavator class and lifting
Match 18–25, 25–30 or 30–45 t and the listed attachment weight, then check the machine’s lifting geometry.
Mounting connection
Provide pin diameters, centres, clear mounting width or quick-coupler information.
Hydraulic flow and controls
Compare the selected 120–200, 150–220 or 200–320 L/min range and controls for reversible shaft motion. The web table does not state operating pressure.
Feed and screening layout
Specify feed material, moisture, contamination and the required fraction; choose the actual shaft and opening rather than inferring them from capacity.
