A Rotary Tube Furnace Shipped to South Africa

Case Overview

In October, a customer from South Africa finalized an order for a rotary tube furnace for material calcination. The client operates a small research and pilot-scale production line and needed equipment that could handle continuous feeding and stable temperature control in the 900–1100°C range. After confirming their material characteristics and throughput requirements, we recommended a mid-size rotary tube furnace with adjustable rotation speed and controlled atmosphere capability.

Customer Requirements

• Continuous processing instead of batch loading

• Uniform heating along the tube

• Stable rotation speed for consistent material movement

• Optional inert-gas environment

• Easy maintenance and simple operation for a small team

The customer sent material parameters and desired throughput, and we adjusted the tube length, feeding angle, and rotation speed range based on these inputs.

Equipment Supplied

• Temperature: up to 1200°C

• Tube size: customized length and inner diameter

• Rotation speed: variable, suitable for both slow calcination and faster drying

• Feeding/collection ports modified according to the customer's material flow

• Digital control system with programmable heating segments

Why the Customer Chose This Model

Instead of going for a larger and more complex system, the customer focused on reliability and practicality. The furnace offered:

• A simple structure

• Straightforward operation

• Stable temperature control

• Compatibility with their existing feeding system

No exaggerated features—just matching their process needs.

Shipment

The furnace was tested at our facility, packed in a reinforced wooden crate, and shipped out in early November. The customer requested remote installation support, which will be provided once the unit arrives at their plant.

Summary

This case is a typical example of supplying a rotary tube furnace for small-scale industrial or research applications. The project was straightforward, with customization mainly focused on process matching rather than high-end configurations. It reflects the kind of practical, fit-for-purpose solutions often needed in real production environments.
