ALLU Variable Drum

The ALLU Asphalt Screening bucket is designed specifically for cold-milled and reclaimed asphalt (RAP) . It crushes clumps, screens fine material, and separates oversized particles – all in a single pass. Thanks to its innovative hybrid blade setup , you get just the right amount of crushing power combined with efficient screening. By handling the majority of the material directly with the ALLU bucket, you drastically reduce the need for expensive impact crushers , cutting down on fuel consumption, wear part replacements, and operating hours. This results in significant savings in both time and money, making the process not only more efficient but far more profitable. Whether you’re processing 100 or 250 tons per hour , ALLU helps you optimize your recycled asphalt handling – keeping your fleet productive and your bottom line strong. The Asphalt Bucket utilizes a hybrid blade configuration – a mix of screening and crushing blades – to fine-tune performance and achieve consistently high-quality end products. This combination allows operators to process cold-milled asphalt directly at the source without additional crushing equipment. With nominal screen sizes of 12, 16, and 25 mm , the bucket can produce over 95% of finished material below target size, drastically reducing reprocessing needs. Key features include: One-Step Operation : Crushes and screens simultaneously, eliminating the need for separate pre-crushing or secondary equipment. Lower Total Costs : Reduces reliance on mobile impact crushers, cutting fuel consumption, wear part expenses, and overall ton-per-cost rates. Proven Throughput : Models deliver up to 250 tons per hour , with rapid drum change-outs thanks to the Variable Drum technology . The DHA-Series consists of 4 models: DHA 3-17, DHA 3-23, DHA 4-17, and DHA 4-23. The first number in the model name is the number of drums, and the last number is the width of the bucket e.g. 17 means 1700 mm. The ALLU Asphalt bucket is engineered to deliver high productivity and long-lasting durability in recycled asphalt processing. At the heart of its performance is the hybrid blade setup , which combines TS standard screening blades with TS Axe crushing blades. This configuration allows you to efficiently screen fines while crushing oversized lumps in a single pass, maximizing throughput and minimizing the need for additional equipment. Supporting this performance is a reinforced frame structure that withstands impacts and abrasion typical in asphalt recycling applications. The frame is built for longevity and stability. Up front, the serrated bolt-on cutting edge improves material penetration and protects the bucket’s lower structure from wear, helping to extend the service life of your investment. The bucket has the Variable Drum structure , which allows for easy blade and drum configuration changes without opening the chainbox. This design simplifies maintenance and reduces downtime. | The ALLU Variable Drum is a new drum structure with a rapid blade change mechanism . Innovation is designed to streamline your operations and boost your productivity. It’s available across our DN-, DS-, and DH-Series. The Variable Drum is a game-changer in material processing efficiency. Versatility Made Simple: The Variable Drum brings flexibility to your workflow. Individual shaft removal allows for quick blade replacements or adjustments to output sizes, all within a matter of hours. This adaptability is crucial for those requiring varied operations from a single Transformer Screening bucket, enabling easy and fast modifications to meet changing job demands. Elevate Your Productivity: Achieve superior screening performance with the Variable Drum, designed for up to a 10% increase in efficiency with a single-blade TS setup. You can get higher output with fewer screening combs and less restriction on material flow. Adjusting output sizes is straightforward, allowing for more efficient operation with less effort. Effortless Maintenance: The Variable Drum’s innovative design simplifies maintenance tasks. Its two-bolt drum attachment system allows easy changes. Changing wear parts or modifying output sizes has never been easier or cleaner, eliminating the need to access the drive compartment and significantly reducing labor time . ALLU Variable Drum is available for all D-Series Screening Buckets. ALLU Transformer D-Series Screening Buckets are designed for larger material handling jobs, from compost aeration to landscaping and construction waste treatment , not forgetting pipeline backfilling . This is a hydraulic attachment for excavators and loaders, that screens, crushes, aerates, mixes, separates, feeds and loads materials in a one-step operation. Efficient – process materials fast and efficiently in one step Mobile – converts your base machine into a mobile processing plant Greener – smaller carbon footprint and reduced material transportation costs Plug & play – simple installation to excavators and wheel loaders Changeable blades – change between different fragment sizes and applications Self-cleaning design – works well even with wet materials
