High Shear Mixer

Tremendous amount of shear is required to produce stable emulsion and fine dispersion. Hence all the impeller blades are designed at high tip speed and high shear rate.
For low and medium viscosity fluid premixing and De-agglomeration of particles to every fine and stable dispersion is a well known use.
For high viscosity fluid co-axial or multi-shaft agitators are recommended with stator rotor or pump may be used for flow through inline homogenizer.
This machine is used for producing stable emulsions and very fine dispersion in micron range. Ultra high shear mixer can be used for sub micron range dispersion and emulsification. 
SEALING OF SHAFT:
Reactors are provided with Gland box or Mechanical seals for shaft sealing arrangement of the shaft with the vessel. 
STUFFING BOX:
Stuffing boxes accomplish sealing by the radial expansion of a soft, deformable material such as layer-wound rubber, plastic, fiber, or a combination of these. Stuffing boxes are lower in initial cost than mechanical seals but are significantly higher in maintenance expenses.
