MB Crusher attachments turn site waste into usable infrastructure material

MB Crusher has highlighted how contractors in India and Australia are using crusher buckets to process demolition and excavation material directly on site, reducing transport movements, disposal costs and reliance on imported aggregates. The two infrastructure projects demonstrate how hydraulic attachments fitted to existing excavators can provide an alternative to bringing additional crushing plant onto site, particularly where space, logistics or tight construction programmes create operational challenges.

Large civil engineering and infrastructure schemes often generate substantial volumes of concrete and excavated material. Traditionally, this waste may be loaded into trucks, transported to a recycling or disposal facility and replaced with purchased aggregate. That process adds haulage costs, increases traffic around the project and leaves contractors exposed to delays caused by vehicle restrictions, material availability and environmental regulations. By processing suitable material at the point of excavation or demolition, contractors can retain greater control over production while reducing the number of journeys entering and leaving the site.

One example comes from the six-lane Kacchi Dargah–Bidupur bridge project in India, where a road construction company is demolishing part of a structure and managing the resulting concrete. An MB Crusher BF90.3 crusher bucket, mounted on a TATA Hitachi EX215 excavator, is being used to reduce demolition material from blocks measuring approximately 250mm to an output size of around 60mm. The processed aggregate can then be reused during the continuing construction works without being transported away from the project. Using the excavator already available on site also helps simplify fleet requirements, as the carrier machine can return to conventional digging, loading or earthmoving duties when the crusher bucket is not required.

A second application can be found near Melbourne, Australia, where Austrak Management & Consulting Pty Ltd developed the Somerton Business Park. Extending for more than one kilometre, the logistics development provides direct links to the region’s principal highways and airports. Material produced through excavation and concrete demolition was processed using an MB Crusher BF120.4 crusher bucket fitted to an excavator working on the scheme. The recovered aggregate was subsequently reused in the construction of internal roads and other infrastructure throughout the business park.

Keeping the concrete within the project reduced the need for off-site disposal and replacement aggregate deliveries, while helping work continue without unnecessary interruptions. This approach can be particularly valuable on major infrastructure and earthmoving projects, where a shortage of trucks or delays at disposal facilities can affect several stages of the programme. Fewer vehicle movements may also reduce fuel use, emissions, road congestion and disruption around neighbouring communities, although the achievable savings will depend on the site, material and transport distances involved.

Crusher buckets can offer contractors and plant hire businesses a flexible method of adding material processing capacity without purchasing or mobilising a separate crusher. As the attachment operates through the excavator’s hydraulic system, carrier compatibility, hydraulic flow, operating weight and attachment requirements must all be considered when selecting the correct model. Output size and production rates will also vary depending on the material, loading method and condition of the concrete being processed.

For fleet operators, the potential benefits extend beyond waste reduction. Reusing suitable material can improve machine utilisation, limit double handling and reduce spending on haulage, tipping fees and virgin aggregate. It may also help contractors maintain control of material quality and availability across road construction, demolition, groundworks, quarrying and infrastructure projects. The Indian and Australian applications show that, on some sites, the most efficient material movement is the one that can be avoided entirely.
