Rotary Tube Furnaces

Rotary tube furnaces are well suited for manufacturing a range of materials, like alumina and iron ore pellets, applications such as calcining, which require the continuous throughput of loose materials, and oxidation. They are designed to withstand high temperatures and offer complete process control, resulting in high-quality products. 

Every Deltech rotary tube furnace is custom designed, meaning we can design them specifically to the size and configuration and with the features needed to meet your process requirements. Those features include those for operation in hazardous environments. We can meet NFPA 86, UL 1203, and C1D2 (Groups D and G) standards as well as those for ASME NQA-1: 2008.   

Before we begin designing your custom rotary tube furnace, we will need some details from you, which include the following:

1. Your preferred tube material if known. For processes which are highly corrosive, specialty metal alloy tubes may be required. Deltech’s Sales and Engineering team can help you to select the best material for your application. 
2. Range of desired angle of the tube
3. Desired rotation speed (3-7 rpm is standard)
4. Feed type (screw conveyor, vibratory hopper, other or none)
5. Density of the material(s) to be processed
6. Retention time (can be adjusted)
7. Does the furnace need to be sealed?
8. Do you need gas mixing and safety features?
9. Do you have PLC/HMI requirements? If so, do you require a specific brand, e.g. Bradley or Siemens, to integrate with your existing system?
10. Do you need the equipment designed for use in hazardous environments?
