Design basis
Define feed rate, inlet and target moisture, particle-size distribution, bulk density, stickiness, attrition sensitivity, allowable product temperature and hazardous dust classification.
Fired & Thermal Equipment · ENGINEERED SCOPE
Industrial Rotary Dryer Systems
Rotary dryer systems remove moisture or volatile components from granular and particulate solids by direct contact with hot gas or by indirect heat transfer through the rotating shell. Feed behavior and product-quality limits are central to the mechanical and thermal design.
Engineering approach
Industrial Rotary Dryer Systems
A technically defined package begins with the operating envelope—not a catalogue model.
Rated capacity, minimum stable load, feed envelope, inlet and outlet conditions, product specification, start-up and shutdown cases, design life and acceptance criteria are agreed before equipment definition is frozen. The review also records utility margins, interfaces, inspection hold points, maintainability constraints and the evidence required for a controlled handover.
Process configuration
Configuration covers direct or indirect heating, co-current or counter-current flow, flight geometry, residence time, burner or hot-gas generator, seals, solids feeding and discharge, dust collection and exhaust treatment.
Verification focus
Checks include heat and mass balance, shell speed and slope, drive torque, thermal expansion, refractory or metallurgy, dust explosion safeguards, emissions, product degradation and maintainability.
PROJECT DEFINITION · DELIVERY
Clear inputs, auditable outputs
Technical proposal quality depends on verified process data, acceptance criteria and interface definition. The following information is confirmed during clarification.
RFQ information
- “Product specification and evaporation”: Define product moisture/temperature, evaporation rate, thermal sensitivity, abrasion/breakage and quality.
- “Arrangement and process parameters”: Select dryer type, residence/rotation, inlet/outlet temperature, gas path and discharge from material properties.
- Site utilities, ambient data, hazardous-area classification and battery limits
- Required performance guarantee, redundancy and availability philosophy
- Applicable project codes, materials, inspection requirements and document format
Engineering deliverables
- Equipment datasheet and design basis for “Industrial Rotary Dryer Systems”, with service-relevant calculations where included in the supply scope.
- Heat and material balance, PFDs, P&IDs and utility summary
- Equipment datasheets, line and instrument lists, control narrative and cause-and-effect inputs
- Layout, nozzle and interface data, foundation loads and maintainability review
- Inspection and test plan, FAT documentation, manuals and final manufacturing record

Discuss this duty with engineering
Share the operating cases, feed data and required guarantee so the applicable process route, package boundary and verification plan can be defined.
Technical Datasheet
Technical Datasheet — Industrial Rotary Dryer Systems
The throughput below is a published complete-system portfolio range, not a guaranteed dry-product rate. Moisture basis and feed properties must be stated before comparing capacities.
| Parameter | Published value | Reference basis | Applicability / limit |
|---|---|---|---|
| Complete-system drying throughput | 10–500 t/h | Published capacity range across complete rotary drying systems. | The source does not define one common wet-feed/dry-product moisture basis across endpoints; do not treat this as water-evaporation capacity. |
| Design variables identified by the supplier | Production rate, moisture removal and temperatures | The supplier states that each system is engineered for the required production, moisture removal, temperature, and product improvement. | Feed PSD, bulk density, inlet/outlet moisture, residence time, gas flow, dust loading, fuel, and emissions limits govern final sizing. |
| Typical integrated equipment scope | Feed handling, dryer/burner, air-pollution control and controls | Published typical complete-plant arrangement. | Exact battery limits and emission-control design depend on material, site permit, and customer scope. |
