Sand
Mobile handling for construction, fill and dredged sand across pits, yards and reclamation sites.
SANTO supplies mobile conveying, stacking and loading equipment engineered for sand — 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 Sand
Sand is a fine, free-draining granular with bulk density 1.5–1.8 t/m³ and an angle of repose near 30–34°. The low feeder track stacker takes direct excavator loading of wet dredged sand and feeds the belt without spillage.
- Low feeder accepts direct excavator loading of wet sand
- Continuous conveying cuts loader haulage on wet yards
- Radial stacking builds clean, dense sand stockpiles
- Belt scrapers manage fine, erosive fractions
- Mobile units follow dredging and pit faces
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 | 1.5–1.8 t/m³ (free-draining) |
| Particle size | 0.06–2 mm, often well-graded |
| Abrasiveness | Moderate; fines are erosive when moving |
| Angle of repose | 30–34° for dry, free-draining sand |
| Handling note | Control fines dust; avoid washing out grade |
Handling Challenges with Sand — and How SANTO Solves Them
Wet, fine sand is heavy and erosive, smearing belts and spilling at fixed drop points; dry sand dusts and segregates fine from coarse.
SANTO low feeder track stackers and conveyors use sealed bearings, belt scrapers and low-drop radial stacking to move sand cleanly. The tracked train follows dredging and pit faces, keeping haul distances short.
- Use sealed bearings and scrapers against fine erosion
- Keep drop height low to limit dust and segregation
- Tracked chassis follows wet, shifting sand faces
Recommended SANTO Equipment
For sand 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.
- Low Feeder Track Stacker — configured for sand duty
- Tracked Radial Stacker — configured for sand duty
- Feeder Track Stacker — configured for sand duty
- Grasshopper Conveyor — configured for sand duty
Typical Stockpiling and Loading Setups
A well-planned sand 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 is wet dredged sand handled?
Low feeder track stackers take direct excavator loading and feed the belt steadily without spillage on soft, wet yards.
Why control sand drop height?
Low drops limit dusting and stop fine segregating from coarse, keeping the grade intact.
Can the equipment follow the dredger?
Yes. Tracked units relocate with the dredging or pit face, holding haul distances short.
