Grain
Mobile handling for wheat, corn, soybean and feed grains across terminals, farms and processing.
SANTO supplies mobile conveying, stacking and loading equipment engineered for grain — 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 Grain
Grain is a fragile, free-flowing seed of bulk density 0.7–0.85 t/m³ that cracks and generates explosive dust if mishandled. The mobile truck unloader draws grain from deliveries and conveys it to silo or pile with low breakage.
- Gentle low-speed transfer minimizes kernel breakage
- Dust suppression reduces explosion risk
- Mobile unloaders receive truck and rail deliveries
- Radial stacking builds aerated, cool grain piles
- Fleet serves farm, terminal and feed mill
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 | 0.7–0.85 t/m³ (free-flowing seed) |
| Particle size | Whole kernels 2–12 mm |
| Abrasiveness | Low, but dusty when handled |
| Angle of repose | 25–35° depending on moisture |
| Handling note | Minimize breakage; control explosive dust |
Handling Challenges with Grain — and How SANTO Solves Them
Grain cracks under hard drops, losing grade and germination, while the fine dust is an explosion hazard. Contamination between crops spoils food-grade lots.
SANTO mobile unloaders and conveyors run at low speed with low drop and dust suppression to keep kernels whole and safe. The mobile train serves farm, terminal and mill, with clean changeover between crops.
- Run at low speed with low drop to avoid breakage
- Suppress dust to manage explosion risk
- Clean changeover prevents crop-to-crop contamination
Recommended SANTO Equipment
For grain 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.
- Mobile Truck Unloader — configured for grain duty
- Radial Truck Unloader — configured for grain duty
- Tracked Radial Stacker — configured for grain duty
- Wheeled Mobile Conveyor — configured for grain duty
Typical Stockpiling and Loading Setups
A well-planned grain 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 grain breakage avoided?
Low-speed, low-drop conveying keeps kernels whole, protecting grade, germination and market value.
How is grain dust controlled?
Dust suppression at transfer points reduces the explosion hazard from fine grain particles.
Can one system serve farm and terminal?
Yes. Mobile unloaders and stackers relocate between farm, terminal and feed mill with clean crop changeover.
