Changing the fragment size on TS-Drums

The patented ALLU Top Screen design enables two different fragment sizes within the same unit. The fragment size is based on the screen comb spacing. There’s no need to remove the drums to change the fragment size. It is a quick and easy way to switch from one screen application to the next.

Available blade sizes and the doubling:

8 mm / 16 mm
16 mm / 32 mm
25 mm / 50 mm
35 mm / 70 mm

When do I need to change the blades on my screening bucket?

Depending on the material and the operating hours, the blades on ALLU Screening Buckets need to be replaced to maintain the quality of the work. A good rule of thumb is that when you’re not happy with the end result – it’s time to check the blades. Lowered processing capacity or changes in the fragment size are usually caused by wear.

The wear on TS-blades can be seen as a shortening of the blade. X- and XHD-blades start to lose their angular shape and become rounded on the edges.

Do I need any special tools when changing drums and blades?

Special tools are required to safely change the drums and blades on a screening bucket. You need an extractor tool for the blades, a bearing unit tool, and a manual cotter press, which are all delivered with the bucket. Impact drill compatible cotter press is available as an accessory (SDS Max head).

We can also provide you with tools for lifting drums safely and to make TS blade installation easier. Always secure the drums to an appropriate hoisting device when moving them to prevent them from falling.

Can I change between different drum types using the same screening bucket?

Yes, different drum types in ALLU buckets are interchangeable and can be replaced without structural changes in the frame.

Please contact ALLU Support for more information.

How long is the warranty period for my screening bucket?

The standard warranty period for ALLU products is 12 months / 1000 carrier hours. An extended two-year warranty is available as an option for DL- & D-Series.

Spare parts have a 6-month warranty period from the date of installation.

What can I crush with the ALLU Screening Bucket?

There is an easy way to check this – If you can break or crush the material with a regular household hammer, you can crush it with ALLU. Materials like limestone, leca blocks, hardened concrete sludge, and other brittle materials are suitable to crush with a screening bucket.

For crushing hard materials like natural rock, we recommend using the ALLU Crusher.

What are the hydraulic requirements for ALLU bucket?

In general, all ALLU buckets require two-way hydraulics (shear circuit) to function as designed.

D-Series:

• Two-way hydraulics & drain line back to tank
• Max. pressure 300 bar, flow 70-400 lpm

DL-Series:

• Two-way hydraulics, no need for a drain line
• Max. pressure 250 bar, flow 60-90 lpm

DC-Series:

• Two-way hydraulics, no need for a drain line
• Max. pressure 200 bar, flow 15-40 lpm

What does the power control valve do in the D-Series?

The power control valve in the D-Series plays a crucial role in protecting the bucket from excess oil flow and pressure. This valve ensures that it is not necessary to manually limit the maximum pressure in the device circuit of the base machine.

All D-Series Screening Buckets are equipped with a power control valve, safeguarding the Transformer against hydraulic overload. The valve automatically begins to regulate the motor’s pressure difference when it exceeds 280 bar and controls the hydraulic flow once it surpasses the model-specific maximum value. This feature is integral to maintaining optimal performance and longevity of your equipment.
