Specific Introduction:
    KJ-1100X-R-15-AF  is a large rotating tube furnace selectable 8" or 15" ID quartz tube with three heating zones and an automatic powder delivering mechanism.   It is designed for syntheses of the inorganic compound with better uniformity at the high temperature up to 1100ºC and 30 L powder.  It can be used to produce battery cathode or Anode power by CVD coating in larger-scale production 
Furnace Construction  
  • Splittable Tube furnace with electric opening/closing function
  • SiC heating element for easy repair and replacing
  • Three heating Zone with total 1000mm(40") heating zone length
  • High purity alumina fibrous insulation structure for max energy saving
  • Gear-driven tube rotation allows "blending" type processing for powders to achieve the best processing uniformity. 
  • Automatic powder feeding and receiving system are included
  • 8" or 15" I.D quartz tube selectable for larger-scale production.
Heating Zone length &
Constant temperature Zone
  • Three heating zones, each zone 330mm ( 13" ) long
  • Total heating zone length: 1000mm (40'')
  • constant temperature zone: 600mm at the center (with +/-5°C) ( if setting all three zones the same heating temperature )
  • Two foam ceramic blocks with alumina coating are included which are connected to flanges and rotate together with the tube.
Working Voltage and Power
  • 208 - 240V AC three phases, 50/60 Hz
  • 45KW Max
 Powder Feeding & Receiving
The processing tube is evacuated to create a vacuum and thus the powder inside the feeder (under atmospheric pressure) will be sucked into the tube due to the pressure difference. A vacuum pump is necessary for such an operation.
  • The furnace can be tilted at a certain degree to allow the powder collection on one side. 
  Quartz Tube
  • High-purity quartz tube, maximum operating temperature: 1100°C
  • Quartz tube size: 400mm OD x 390mm ID x 1800mm L or  216mmOD x  205 ID x 1800mm L
  • Two alumina blocks are included to keep powder within the heating zone
  • The inside tube is welded with stirring blades to make the powder sintering more fully and evenly.
  • Max. Loading: ~ 30 Liter Powder
 Sealing Flanges
  • The sealing flanges are provided with the processing tube. The standard configuration is:
    • Both flanges are the quick-connect type. 
    • One mechanical pressure gauge (range: -0.1Mpa - 0 Std atm - 0.15Mpa)
  • The rotating seal is a magnetic fluid seal to guarantee that the front end of the flange does not move when the tube rotating under a controlled atmosphere.
Temperature Controller
  • Three 30 segments programmable PID digital temperature controller 
  • The RS485 communication port is built-in
  • Note: To achieve full temperature computerization please order a set of MTS-02 control modules. If you order the control module with the furnace we will install and test it before we ship out the product. We recommend you order the computer (laptop) from us.
Working Temperature
  • Max. working temperature: 1100oC for less than 30 minute
  • Continuous Working Temperature:  400 -1000°C 
  • Max. Heating/Cooling rate: 10°C/min 
  • Temperature accuracy:  +/- 5°C in heating Zone
Tube Rotating Speed 3 - 10 RPM variable
Furnace tilt angle 0 - 15°  adjustable by electric driven motor
Gas Mixing System (Optional) 
  • For Powder CVD coating, you will need to order a optional gas delivery system. 
  • 4 Channels gas mixer: GSL-4Z (Optional. Customers can order in different multiple channels gas mixer with extra cost)
  • Accuracy: ±1.5% FS
  • Liner: ±(0.5-1.5)%F.S.
  • Accuracy: ±0.2%F.S.
  • Controlling Range:
    • Controller 1: 0~100 SCCM
    • Controller 2: 1~199 SCCM
    • Controller 3: 1~199 SCCM
    • Controller 4: 1~499 SCCM
  • One-year limited warranty with lifetime support (Consumable parts such as processing tubes, o-rings and heating elements are not covered by the warranty, please order the replacement at related products page.)
  • CE Certified
  • NRTL certification is available upon request at extra cost.
