Construction Waste
Mobile handling for mixed construction and demolition debris at crushing, screening and recycling sites.
SANTO supplies mobile conveying, stacking and loading equipment engineered for construction waste — from receiving and stockpiling to reclaim and load-out. The notes below cover the properties that matter, the problems that typically appear on site and the machines we recommend.
Why Mobile Conveying Suits Construction Waste
Construction waste is heterogeneous debris — concrete, brick, wood, metal — of bulk density 1.0–1.8 t/m³ that arrives in surges. The low feeder track stacker takes direct excavator loading and feeds the crusher steadily for on-site recycling.
- Low feeder takes direct excavator loading of debris
- Steady feed keeps the mobile crusher at capacity
- Tracked mobility crosses rough, debris-strewn sites
- Belt scrapers survive gritty, dusty environment
- Mobile train packs up and moves to the next job
Physical Properties and Handling Behaviour
The table below summarises the properties that decide belt specification, chute geometry and stacking method for this material. Values are typical ranges — actual figures vary with source and moisture content, so we test your sample before finalising a design.
| Property | Typical Value / Handling Impact |
|---|---|
| Bulk density | 1.0–1.8 t/m³ (mixed, variable) |
| Particle size | Fines to large reinforced chunks |
| Abrasiveness | High from concrete and brick |
| Angle of repose | 35–42° for crushed C&D |
| Handling note | Separate fractions; steady crusher feed |
Handling Challenges with Construction Waste — and How SANTO Solves Them
C&D debris is mixed, surge-loaded and abrasive, with metal and wood that jam fixed plant. Without steady feed, on-site crushing — the route to reuse revenue — stalls.
SANTO low feeder track stackers and grasshopper conveyors use impact beds, abrasion-resistant belts and sealed bearings to move debris cleanly, metering a steady crusher feed. The tracked train relocates between sorting, crushing and stockpile as the site reconfigures.
- Use impact beds and abrasion-resistant belt for debris
- Meter steady feed to keep the crusher running
- Tracked chassis crosses rough, debris-covered ground
Recommended SANTO Equipment
For construction waste we most often supply the machines listed below. Each can be configured with the belt width, boom length and drive power your tonnage requires, and each is available on wheeled, tracked or crawler chassis.

- Tracked Stockpiler — configured for construction waste duty
- Feeder Track Stacker — configured for construction waste duty
Typical Stockpiling and Loading Setups
A well-planned construction waste yard keeps receiving, stacking and reclaiming on separate paths so trucks never queue behind a loader. In the most common layout, a mobile conveyor receives from the tipper or hopper and feeds a radial telescopic stacker that builds a layered stockpile, while a second conveyor reclaims to the loading point.
- Receiving: hopper or direct truck discharge into a mobile conveyor
- Stacking: radial or telescopic stacking to build layered, drainable stockpiles
- Reclaim: front-end loader feeding a mobile conveyor, or direct reclaim conveyor
- Load-out: conveyor to truck, wagon, barge or vessel hold
Frequently Asked Questions
How does mobile conveying aid C&D recycling?
Steady feeder metering keeps the crusher at capacity so more debris becomes reusable aggregate instead of landfill.
What wear protection does debris need?
Impact beds, abrasion-resistant belt covers and sealed idlers survive the gritty, mixed concrete-and-brick load.
Can it work on a messy site?
Yes. Tracked chassis traverse debris-strewn, uneven ground that wheeled plant cannot, and the train packs up between jobs.
