Commonly used trade names and technical identifiers for Rotating Drum.
This component is essential for the following industrial systems and equipment:
| pressure: | Atmospheric (non-pressure vessel, but must withstand internal dynamic loading during rotation) |
| flow rate: | Not applicable (batch process, not continuous flow) |
| temperature: | -10°C to 50°C (ambient operating range, concrete mix temperature typically 5°C to 35°C) |
| max capacity: | Typically 6-12 cubic yards (4.5-9 cubic meters) |
| rotation speed: | 0-15 RPM (mixing), 1-3 RPM (transport/discharge) |
| slurry concentration: | Up to 80% solids by volume (typical concrete mix design) |
Indicative industry ranges for design and RFQ preparation. Confirm the exact figures and applicable standard with the manufacturer before specifying.

A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
The typical capacity range is 6 to 16 cubic meters, depending on the truck model and intended use. Always confirm the exact capacity with the manufacturer for a specific vehicle.
The drum rotates continuously at a mixing speed of 6–10 RPM during transit. This constant motion keeps the concrete ingredients uniformly mixed and prevents heavier aggregates from settling to the bottom.
Reversing the rotation direction and increasing speed to 14–18 RPM causes the internal helical blades to push the concrete toward the open end, allowing it to discharge through the chute. The tilt angle of 10–15 degrees assists this process.
The drum is typically made of high-strength, abrasion-resistant steel, often grade Q345B low-alloy high-strength structural steel per GB/T 1591. The shell thickness is usually 4–6 mm. Verify material specifications with the supplier.
