Recycling
Effective recovery of concrete and scrap.
Effective solutions in concrete and scrap recovery
Reusing demolition and construction waste (reinforced concrete, steel, brick, timber) is gaining importance for both cost and environmental sustainability. The goal is to separate the waste on site or at the plant and turn it into recycled aggregate and scrap metal.
With HKM attachments concrete is ground, rebar is separated from the concrete, and mixed waste is classified by type. Clean separation raises output quality and lowers landfill cost.
Related Products
Bring large pieces to feed size
Cuts large reinforced-concrete pieces to a manageable size and strips the rebar; feeds the next grinding step with clean material.
Detailed use scenario
Concrete-rebar separation
Finely grinds the concrete and separates the steel rebar; delivers clean concrete and separate scrap steel for recovery, working with low noise.
Detailed use scenario
Metal cutting and separation
Speeds up separating metal as scrap by cutting steel profiles and rebar; increases metal recovery in mixed waste.
Detailed use scenario
Turn into aggregate on site
Grinds waste concrete directly into recycled aggregate on site; reduces the need for hauling and separate processing equipment, working with a single operator.
- Waste concrete is fed into the bucket and crushed on site into recycled aggregate.
- The output is set aside as backfill, sub-base or for on-site use.
- For reinforced pieces, rebar is stripped with a pulverizer first, then crushed in the bucket.
Uninterrupted flow between attachments
On the recycling site it switches between shear, pulverizer and grapple in seconds without the operator leaving the cab; cutting, grinding and sorting continue in one uninterrupted flow with a single carrier.
- Cutting (shear), grinding (pulverizer) and sorting (grapple) steps are sequenced on one machine.
- The attachment change takes seconds from the cab, so the material flow never stops.
- More processing steps are completed with fewer machines, lowering site cost.
Sort, separate and load
Selects, separates and loads mixed waste of concrete, metal and timber by type; precise gripping reduces hand-picking.
- Concrete, metal and timber are separated from mixed piles into their own containers.
- The rotator grips and stacks each piece at the best angle.
- Less hand-picking means better site safety and speed.
Frequently Asked Questions
Which attachments are used in recycling?
Pulverizers and crusher buckets for concrete separation and rebar recovery, hydraulic shears for scrap/metal cutting, and grapples for material handling.
What should I use to separate rebar from concrete?
Pulverizers crush concrete and free the rebar; crusher buckets size material on site for reuse.
How do I choose the right class for a scrap yard?
Cutting force and jaw type are set by the material and carrier tonnage. Share your needs and we will recommend the right shear/grapple class.
