A Screening Bucket Analysis by Flipscreen

We would like to share with people who may be in the market for a screening bucket or who may be wondering what exactly a screening bucket can do for them, a few basic questions. These questions will serve to highlight the functionality and performance criteria of a screening attachment. Each question has just a brief summarized answer. For more information: https://www.flipscreenglobal.com/screening-bucket/ 

Without further ado, herewith the questions: 

  1. Is the bucket watertight? Can you scoop up material and move around the site without spilling the contents?

With most other “screening attachments”, as soon as the material is scooped, it will spill through the bucket. The FlipScreen’s base is similar to that of a standard bucket which is watertight, enabling the operator to drive around the site with a full load without spilling.

2. How long does it take you to change the mesh size, where can you change it, and with what tools?

With a Flispcreen, simply unlatch the load binders on the mesh, re-enter the carrier, and upon activating the hydraulics, the old mesh is released. Then move the bucket to the new mesh, and on operating the hydraulics, the new screen is rotated onto the bucket, which can then be secured. Under 5 minutes, with no tools, one operator and on-site.

3. Is the screening bucket able to be used underwater?

FlipScreens are built using durable, high-grade seals enabling them to screen underwater, transforming it from a screener into a mobile wash plant.

4. What materials is the bucket capable of separating?

Flipscreens are built from high tensile steel, with no internal moving parts. Its’ action keeps material within the confines of the bucket. This means it can screen any material it can scoop such as concrete with reinforced steel, and scrap metal. Other attachments struggle to achieve this, and those with internal moving shafts find entanglement with reinforced steel a disaster.  

5. Does the screening bucket have the biggest screening surface area in its class?

Compared to other attachments on the market, FlipScreen has the largest screening surface area of its class, which explains the high-volume screening rates. For example, a WL180 wheel loader screening bucket has a screen surface area of 73.2 square feet (6.8 square meters). Every 2.5 seconds, the material is inverted and then travels the whole area of the mesh.

6. Can the attachment dig fresh ground?

The FlipScreen can break into the unexcavated ground. Some other screener buckets, if care isn’t taken while scooping, can structurally damage the attachment or distort the inner barrel. Not an operator error but simply poor design. This saves time as there is no need to take off the attachment and use rippers and standard buckets to stockpile the material separately.

7. Is the bucket able to break up clumps with its action?

After approx. 3 rotations (7.5 seconds), fines are screened and the exposed lumps will start to be smashed onto the rear mesh, from the unique action of the Flipscreen as it lifts and flips the material. This enables the operator to either break up the remaining lumps or tip them. Some attachments cannot break up material, e.g., washing machine types.

8. Is the screening bucket able to be used with corrosive material?

FlipScreens have replaced hundreds of so-called portable screening plants all over the world in the scrap industry as this type of application is simply impossible to achieve with a standard portable screening plant. Flipscreens can easily screen corrosive fertilizer with our stainless-steel mesh.

9. Can the screener bucket use either fine or large aperture meshes to screen different size material?

The standard mesh range for FlipScreens starts at a 3 mm aperture and goes all the way up to 300 mm aperture (0.12″ to 12″). Custom meshes can also be designed on demand for particular applications.

10. Can the bucket also be used as a concrete mixer?

The FlipScreen’s inward spiraling action means that it can easily be converted into a concrete mixer by way of a FlipScreen mixing plate. This replaces the mesh and transforms the bucket into a mixer.

11. Is the screening bucket able to be switched between carrier machines without requiring a hydraulics technician?

The FlipScreen’s revolutionary, “plug and play” smart valve enables the attachment to be switched between carriers without hydraulic alterations. This saves time and money. In many cases it enables the FlipScreen to take “incorrect” pressures and flows while maintaining the correct speed and action without any negative effects to the FlipScreen or carrier. The end result is ramping up to the correct speed and torque and ramping down smoothly to zero.

12. Does the screening bucket have realistic load ratings?

FlipScreen has multiple models to ensure that each carrier combination is within safe working tolerance to not overload. Do not use attachments with unrealistic carrier weight range as these will cause dangerous overloading. Add the weight of the attachment and the load capacity multiplied by the relative weight of the material to ensure that you are not endangering your operator.

13. Does the screener bucket have a reversible, bolt-on, replaceable cutting edge/blade?

Other than the mini FlipScreens, all units come with a reversible, bolt-on cutting edge. Which means new cutting edges can be fitted in the field without needing to cut out the cutting edge and weld in a new one. Most screening buckets do not have this feature. This feature is needed as the durable FlipScreens have a long operating life.

14. Can the bucket also be used as a standard bucket?

FlipScreen offers the biggest range of carrier options to replicate the standard bucket on each. Allowing for standard functions & screening. It feels like a standard bucket on an excavator and the operator can see through to the cutting edge on a loader. The FlipScreen is watertight, enabling the operator to drive the site with a full load without spilling.

15. Does the screening bucket have internal moving parts inside the bucket?

The inside of the FlipScreen is completely empty, relying purely on the external shape to carry out its functions. This allows screening of almost any material. Some screening attachments have multiple moving internal parts, producing a high wearing environment and prone to fouling, jamming and tangling of material such as wire and string which are commonly found in waste.

16. Can the screening attachment be used to blend material?

FlipScreen is outstanding as a blender, whether it be with a normal mesh or with the mixing plate attached. The unique, flipping action ensures that material is combined thoroughly. Other screening attachments don’t report to be mixers.

17. Is the screening bucket able to screen into trucks, or dump oversize into trucks?

The FlipScreen can be used to load trucks. Screening directly into the truck, or scooping and dumping like a standard bucket. The FlipScreen still has a normal crowd function of a standard bucket. Other screening attachments are not suited for this as they inherently start to spill as soon as material is scooped ruling them out as a loading bucket.
