Rotary Kiln (Single-Tube/Multi-Tube)

Rotary Kiln (Single-Tube/Multi-Tube)

Equipped with newly-developed technologies optimized for resource recycling processes, etc., this rotary kiln is the next step in the continuous evolution of Chugai Ro’s world-class thermal technology,
and contributes to our customers’ efforts to develop functional materials and achieve zero emissions.

Equipment Features

Heating technology with gentle rotation and agitation

  • Temperature and atmosphere contact unevenness has been eliminated, resulting in uniform heating inside the furnace.

Compatible with all atmospheres

  • Compatible with all kinds of atmospheres such as air, non-oxidizing, hydrogen (100%), and steam, etc.

Max. temperature 1,100 °C

  • Use is possible in a wide range of temperatures, from low-temperature to high-temperature firing, based on the selected retort.

Fine temperature program setting possible

  • Heat treatment can be performed under various conditions by specifying temperature rise/fall program settings.
  • Furthermore, the use of IoT technology allows remote monitoring and setting.

Fully equipped with automatic operation systems

  • Productivity improvements are achieved with automatic continuous and semi-continuous operation systems.

Comprehensive powdered material heating plant

  • Can be delivered as an integrated plant capable of handling raw material stock to finished products.
Use

In addition to the firing and calcination of all kinds of powdered material, the features of this external heating type rotary kiln can be leveraged to address a wide range of applications such as oxidation, reduction, and decomposition under various atmospheres, as well as catalyst generation and regeneration.

Equipment Structure

A fixed quantity of material fed by a screw feeder is lifted up while being rotated, and is then lowered and agitated near the material angle of repose. This process is repeated, and the material is fed to the exit.
IoT

Supports remote monitoring through the use of IoT technology

Use of IoT technology contributes to "improved safety and stability", "improved productivity", and "higher quality".
