ALLU Introduces New Concrete Screening, Crushing Bucket for Onsite Demolition Recycling

As demolition projects become larger, urban job sites become tighter and material disposal costs continue to rise, contractors are looking for more efficient ways to process concrete waste. Rather than hauling broken concrete off-site for crushing before bringing aggregate back to the project, many are moving toward processing material where it is generated.

That's the problem ALLU set out to solve with its new concrete screening and crushing bucket, an excavator-mounted attachment designed specifically for demolition and recycling applications.

Built for excavators in the 25- to 45-ton class, the new bucket crushes and screens concrete, brick, asphalt and reinforced demolition material directly onsite, helping contractors reduce transportation costs while creating reusable material for the next stage of construction.

The launch reflects a broader shift across the construction industry toward attachment-based material processing, where existing machines perform multiple functions without requiring additional dedicated equipment.

Why Onsite Concrete Processing Matters

Concrete remains the most widely used construction material in the world, and as infrastructure continues to age, demolition volumes continue to increase.

For contractors, that creates two challenges. The first is logistics. Demolition rubble is heavy, bulky and expensive to transport. Every truckload leaving a project represents additional fuel costs, trucking expenses, disposal fees and labor.

The second challenge is productivity. Conventional recycling workflows often require material to be loaded, transported, crushed, screened, transported again and eventually returned to the project as usable aggregate. Each additional handling step adds cost and extends project schedules.

On urban job sites where space is limited, bringing in a dedicated mobile crusher may not even be practical. By allowing contractors to crush and screen demolition material with the excavator already working on-site, the ALLU concrete bucket simplifies that workflow considerably.

Built for Demolition Conditions

Unlike clean aggregate processing, demolition material rarely arrives in ideal condition.

Concrete is frequently mixed with reinforcing steel, brick, asphalt, fines, soil and oversized material. Those contaminants can interrupt production and reduce efficiency when processing equipment is not designed for real-world demolition feed.

The ALLU concrete bucket is engineered to process these mixed material streams while handling rebar and other steel objects commonly found in demolition rubble. Instead of stopping repeatedly to clear material, contractors can maintain continuous production throughout the crushing process.

That capability is particularly valuable for demolition contractors, recycling facilities, and municipal infrastructure projects where material consistency can vary significantly throughout the day.

Crushing, Screening in One Attachment

The new attachment combines crushing and screening into a single excavator-mounted solution.

Material up to approximately 12 in. enters the bucket, where three rotating crushing drums reduce larger pieces while allowing fine material to pass through. A reversible drum rotation system maintains material flow while utilizing both upper and lower crushing plates for consistent processing.

Contractors can select between two finished material sizes: 0-2 in. or 0-4 in. Depending on the application and carrier machine, production capacity can reach approximately 110 tons per hour, making the attachment suitable for demanding demolition applications while maintaining the mobility advantages of an excavator attachment.

Heavy-Duty Design for Demanding Applications

ALLU designed the concrete bucket specifically for demanding demolition environments.

The attachment features a reinforced frame with a heavy-duty cutting edge and side cutters engineered to withstand the breakout forces generated by excavators up to 45 tons. Replaceable carbide-tipped crushing picks simplify maintenance while helping maintain consistent crushing performance over extended operating hours.

Instead of transporting and positioning a separate crusher, contractors can move quickly between work areas using the excavator already performing demolition work. This reduces setup time while improving overall jobsite flexibility.

Supporting Sustainable Construction

Construction companies continue looking for practical ways to improve sustainability without sacrificing productivity.

Keeping material at the project reduces truck traffic, lowers fuel consumption, minimizes emissions associated with transportation and decreases demand for virgin aggregate. At the same time, contractors retain greater control over project schedules because reusable material becomes available immediately after demolition.

Instead of viewing concrete rubble as waste, more contractors are recognizing it as a valuable construction resource.

Continuing ALLU's Material Processing Philosophy

For more than 40 years, ALLU has developed attachment-based solutions that help contractors process materials where they are generated.

The new concrete screening and crushing bucket continues that approach by giving excavators another capability beyond digging and loading. Rather than adding another machine to already crowded job sites, it enables the carrier machine to become an efficient onsite processing solution.

As demolition projects continue to grow in complexity and pressure mounts to improve recycling rates while controlling costs, solutions that simplify material handling are becoming increasingly valuable.

For many contractors, the future of concrete recycling may not involve adding more equipment. It may simply involve getting more out of the excavator that's already on-site.
