A bucketload of ValuePublished 11/3, 2022 at 09:22
Crusher and screening buckets are the kind of tools that quite literally turn waste into profit. Powerful and versatile attachments, they can be fitted on a carrier of any kind - excavator, loader or even telehandler - to process a wide variety of materials from construction and demolition waste to topsoil, turf, roots and compost. PDi’s Andrei Bushmarin presents the latest news from this fast developing sector.
Let’s crush & screen in the Rock.Zone!
Germany-based manufacturer formerly known as Rokla, which last year got rebranded as Rock.Zone, keeps upgrading its portfolio of crushing and screening attachments. The crusher bucket range brand named ‘Rockcrusher’ currently includes four models that fit 12t to 35t carriers. Thanks to the in house ‘Quattro Movement’ crushing technology, the buckets produce a consistent cube shaped end product, which is immediately ready for re-use as aggregate. Other benefits include reduced wear on the jaw plates and the possibility to crush round shaped materials such as river rocks and pebbles. The reverse function allows the jammed material to be ejected at the flick of a switch. The bucket’s side plates are replaceable to avoid wear on the crusher’s frame. The new options include cover protection, a set of hand tools, bucket nose extension and longer hoses (2.5m instead of the regular 2m). The ‘Rockscreener’ series of screening buckets includes five models suitable for 9t to 39t machines. The Rockscreeners are said to have three major advantages over competition: the XXL hopper volume allows large quantities to be processed in one step; the XXL drum has a honeycomb structure for improved uniform screening and a maintenance free extra-large gearbox.
No job is too difficult for Simex screeners
Italy based Simex has upgraded its ‘VSE’ screening buckets, available in four models for 8t to 45t excavators, with a new screening tool system called ‘FIT’. It is composed of five independent parts designed to easily interlock with each other. They are easily replaceable without the need for removing the shafts, which leads to reduction in maintenance costs of up to 75%, since it is now possible to replace just one single disc or blade. The system allows multiple configurations depending on the material being screened. Simex provides users with three basic set ups, but more options are possible thanks to fully interchangeable screening elements.
A few examples of the new system in action include a VSE 30 screening bucket being used in the province of Modena, Italy, for the separation and recovery of materials following the demolition of a private home. The bucket separated the larger sized material (40mm-100mm) from the finer one (0-30mm) while sifting away debris and soil. The VSE 30 was equipped with the FIT disaggregation tool, featuring a central blade, which also does some crushing of the concrete during the screening. In the county of Lancashire in the UK, an operator cleaned tons of topsoil from stones and gravel for landscaping purposes using a VSE 30 bucket. The final product was a fine size aggregate ready to be transported and reused. The coarse aggregates, greater than 55mm, were used directly onsite. In Bologna, a VSE 30 carried out a land remediation project around a construction site by selecting and separating soil from demolition waste. Sifting soil from stones, roots and debris made it possible to quickly restore the green area while reusing 100% of the material present onsite. Despite high soil humidity caused by intense rains in the days prior to the job, the production rate was still impressive, varying between 20m³/h and 25m³/h.
Allu launches new ‘DC Series’ for the Chinese market
In 2021, Finland based attachment specialist Allu opened its new manufacturing plant in China to cater for the needs of the local market. Following the commissioning of the facility, the manufacturer launched the new ‘Transformer DC Series’ tailored to the Chinese market. The Transformer DC Series are screening buckets for a variety of screening, crushing, mixing and aerating applications. All models come equipped with two hydraulic motors for maximised performance. The attachments have reinforced sides for work in the harshest environments. The Transformer DC Series offers two different blade options. Equipped with ‘TS blades’ the buckets are ideal for screening, separation and aeration applications. The TS blades rotate between the screening combs, with the resulting fragment size varying between 25mm and 50mm. The final product size can be adjusted by repositioning the screening combs. This allows users to get two fragment size options with the same bucket at no extra cost. The buckets that feature ‘X-blades’ are used for stabilisation, mixing, aeration and crushing. The design is clog proof, with production rates remaining high even with wet materials.
