Rotary Dryer
Continuous drying for mineral, aggregate and industrial feed. Drum, flight and gas-flow configuration are reviewed against moisture-removal targets.
Configured around the actual process duty
The Rotary Dryer is selected from confirmed material, feed, capacity, product and site information. Its duty is reviewed together with upstream feeding, downstream transfer, classification, utilities, maintenance access and the agreed operating schedule.
Suitable feed
Mineral, aggregate or industrial feed with confirmed inlet moisture and thermal sensitivity.
Process position
Moisture reduction before storage, grinding, thermal processing or final use.
Engineering focus
Inlet and outlet moisture, feed rate, heat source, gas flow, residence time, flights, dust collection and controls.
Convective drying in a rotating drum
Internal flights lift and shower material through a controlled gas stream. Heat and mass transfer remove moisture as the product advances to discharge.
Stable performance depends on controlled feed, correct operating settings, suitable wear or process components and effective coordination with the surrounding plant.
- Application reviewed from confirmed material and duty data
- Operating configuration matched to the required process result
- Wear, maintenance and access requirements considered during selection
- Upstream and downstream equipment reviewed as one process
Information required before model confirmation
Catalogue ranges support early planning. Final capacity and equipment selection require confirmed project data.
| Review item | Information to provide | Engineering impact |
|---|---|---|
| Material properties | Material name, hardness or strength, abrasiveness, moisture and contamination. | Equipment suitability, wear selection and power demand. |
| Feed conditions | Maximum size, typical grading, feed rate and feeding method. | Inlet, loading pattern and upstream configuration. |
| Required duty | Target capacity, operating hours and expected availability. | Equipment size, drive duty and complete circuit capacity. |
| Required product | Target result, discharge specification and downstream process. | Operating configuration and downstream arrangement. |
| Site conditions | Country, altitude, power standard, utilities, installation and layout constraints. | Motor, controls, structure, access and delivery documentation. |

Common selection questions
What information is needed to select this equipment?
Share feed and target moisture, throughput, material behavior, heat sensitivity, fuel, ambient conditions and site utilities.
Does the published capacity guarantee site performance?
Drying output depends on inlet moisture, required outlet moisture, heat balance and material residence time; published capacity is not a guaranteed dry-product rate.
Can the target outlet moisture be confirmed?
It can be assessed from representative feed data and the proposed heat balance; any performance commitment belongs in the agreed technical documents.
What systems are considered with the dryer?
Heat source, feeding, discharge, dust control, exhaust handling and controls should be reviewed together.
Which service parts may be needed?
Seals, drive components and other wear items depend on the selected dryer and actual temperature and material duty.
