Cement Clinker
Mobile handling for hot clinker, gypsum and additives across cement quarries, plants and terminals.
SANTO supplies mobile conveying, stacking and loading equipment engineered for cement clinker — 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 Cement Clinker
Cement clinker is hot (up to ~1450 °C at discharge, cooling to ~100–200 °C), abrasive nodules of bulk density 1.2–1.5 t/m³; additives are fine and dusty. The tracked radial stacker builds layered, homogeneous clinker piles that smooth kiln feed.
- Layered radial stacking improves clinker homogeneity
- Heat-resistant belts survive warm nodules
- Enclosed transfer controls fine additive dust
- Continuous feed protects kiln chemistry
- Mobile fleet serves quarry, mill and loadout
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 | 1.2–1.5 t/m³ (cooled clinker) |
| Temperature | 100–200 °C at conveyor (post-cooling) |
| Abrasiveness | High — hard, angular nodules |
| Angle of repose | 33–38° for clinker |
| Handling note | Heat-resistant belt; seal fines; layer pile |
Handling Challenges with Cement Clinker — and How SANTO Solves Them
Warm clinker is abrasive and degrades belt covers, while fine additives and dust breach permits if airborne. Poor pile mixing also destabilizes kiln chemistry.
SANTO tracked radial stackers use heat-resistant belts and a cooling load zone, with sealed transfer for additives. Layered radial stacking builds homogeneous piles that smooth mill feed and cut fuel use.
- Use heat-resistant belt and a cooling load zone
- Seal additive transfer against fine dust
- Layer the pile for homogeneous kiln feed
Recommended SANTO Equipment
For cement clinker 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 Radial Stacker — configured for cement clinker duty
- Feeder Track Stacker — configured for cement clinker duty
- Grasshopper Conveyor — configured for cement clinker duty
- Mobile Truck Unloader — configured for cement clinker duty
Typical Stockpiling and Loading Setups
A well-planned cement clinker 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 warm clinker handled on a belt?
Heat-resistant belt covers and a load zone that lets material cool before full speed protect the conveyor from thermal damage.
Why layer the clinker pile?
Radial layered stacking builds homogeneous stockpiles that smooth kiln feed and reduce fuel per tonne of cement.
Can the same fleet serve additives?
Yes. Sealed transfer handles fine gypsum and additives, while the mobile train serves quarry, mill and loadout.
