Rotary Tube Furnace

1200℃ Rotating Tube Furnace, 3-7 RPM

BR-12RTF High Temperature Rotary Tube Furnace, 1200℃ Rotating Tube Furnace, 3-7 RPM is designed for calcining inorganic compound with better uniformity, especially excellent for preparing Li-Ion battery cathode materials with a conductive coating, such as LiFePO3, LiMnNiO3, etc in R&D Laboratory.

  • Max temperature 1200 ℃
  • 50 segments programmable and PID auto control
  • Heating rate: 0~20 ℃/min
  • Temperature accuracy: ±1 ℃
  • Upper open furnace cover design for real-time observation of heated materials
  • Furnace tilt angle 0 – 30℃ variable, it’s convenient for loading and unloading material
  • Tube rotating Speed 3 – 7 RPM variable ( reversible), and there are 3 quartz lifting plates on the inner wall of the tube. When rotating, the material is fully turned over and evenly heated.
  • It has safe operation functions such as opening and closing power, over temperature alarm and leakage protection
