Rotary screening bucket

Rotary screening bucket on the arm of an excavator, drum turning, the fines falling in a shower onto a heap, on an urban earthworks site
The drum turns:
the fines go through the grid, the oversize stays inside.
Synthetic image.

A drum that turns, and material that breaks up as it turns.
The fines pass through the grid:
the oversize stays inside and is emptied out at the end of the cycle.

Other names for this tool: drum screening bucket, rotary screen bucket, rotary screening skip.

01 Use

What it is for

On the left, the drum turns, the fine topsoil passes through and forms a heap, the stones stay inside. On the right, waterlogged soil sticks to the bars, clogs the screen and comes out just as it went in. Computer-generated image.

The drum of a screening bucket turning, the clods breaking up inside, and the fine material falling in a continuous curtain below.
The stirring breaks up instead of rolling:
that is what separates a rotary screener from a plain grid.
Synthetic image.

The loaded material is set turning inside the bucket.
The stirring breaks up the clods instead of rolling them on a still grid:
the fines go through, the oversize stays inside, and you empty it at the end of the cycle.

Topsoil, spoil, compost, sand laden with stones:
everything that is separated by size and not by nature.
The benefit is measured by the lorry that does not leave and by the imported material you do not buy.

A screen washes nothing and does not sort by nature. Soil saturated with water sticks, clogs the grid and comes out as it went in, whatever the tool and whatever the machine.
The moisture of the material decides the output long before the choice of bucket.

02 Key technical data

On which machine?

They exist for machines from 3 to 50 t.
For example, on an excavator over 20 t, the weight is generally from 1 420 to 2 830 kg.

What the tool does

It is used for recycling and reclaiming.
For example, for a width of 1 900 mm: capacity from 1 000 to 1 400 l, weight from 1 140 to 1 420 kg.
Depending on the model, the teeth are interchangeable or offered as an option, to be checked with you.

What is needed on the hydraulic side

It needs a double-acting hydraulic circuit.
It generally needs from 20 to 280 l/min, at a pressure from 120 to 160 bar, depending on the size of the machine.
The flow and the pressure: we calculate them with you for your machine.

03 Your study

Have your machine checked.

Describe the material, its average moisture and the cut you are aiming at.
Tell us also what carting away costs you today:
that is where the calculation is made.

What we need to answer you
  • Your machine Its make and its tonnage.
  • The auxiliary circuit Its flow in l/min, its pressure in bar, single- or double-acting.
  • The coupler in place Its system and its class.
  • The work The use, and the material.

Without these details, the study still begins: we will ask you for them.

The drum turns: the fine soil passes through the mesh and falls in a heap; the stones and roots stay inside.
The topsoil is sorted on the spot, at the foot of the house.

04 Choice

What determines the choice

  • 01 — The cut you are looking for It is what governs the grid — and the grid can be changed.
  • 02 — The moisture of the material The same bucket gives two opposite results depending on the season.
  • 03 — The hydraulics available A screening bucket consumes continuously, not in bursts.
  • 04 — The empty weight, then the loaded weight It is heavy before it has picked up anything at all.
05 Check

What is checked before ordering

  • The material to be screened Nature, moisture, presence of roots and unwanted items.
  • The destination of the two fractions Reuse on the spot, stockpiling, carting away.
  • The flow and the pressure at the end of the dipper arm At the outlet, not at the pump.
  • The load chart with the bucket loaded Screening is often done at height, to tip onto a heap.
