Twin Shaft Paddle Blender

  • Paddles mounted on twin shafts in a ‘w’ shaped trough
  • Normal filling level of material in the mixer is slightly above the shafts
  • Overlapping motion and paddle design facilitates rapid fluidization and ensures excellent movement of particles
  • Surplus space in the mixer trough to provide air around the particles so that they can move freely
  • Twin shaft, counter-rotating paddles lift the particles in the centre of the mixer trough, in the fluidized zone, where mixing takes place in a weightless state
  • Normal working volume is about 25 percent of the total volume of the trough
  • Range of operation of the mixer is 40 to 140 percent of the rated capacity
  • Peripheral speed ~100 metres per minute
  • Mixing time can be as low as 1 minute. Mixing homogeneity of 98 – 99 percent.
  • Choice of discharge valves including half bomb bay doors, spherical disc valves are available.
  • High speed choppers can be provided
  • Rotating twin shaft paddle mixers are the most recent development.
