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.
