Disadvantages
|
Paddle
|
Mixing of Solids,
Slurry Mixing, Used during Crystals forming phase during Super saturated Cooling |
Heavy duty,
Apt for Slow operation, Can have 2 or 4 blades |
|
Turbine
Straight Blade Pitched Blade Curved Blade Disk Blade |
Liquids and Gas reactions,
Highly used during Reaction and Extraction Operations. |
Generates high Radial Flow,
Highly used for dispersion operations |
Not preferred for solvents with high viscosity[NMT 20 cP]
|
Screw type
|
Have to use in addition to other agitators.
Mostly used in Food processing. |
Uniform mixing of High viscous masses.
|
Not preferred for im-miscible solvents.
|
Helical Blade
Ribbon Type Helical Screw |
Most Probably used in Paint industry.
|
Can handle Visco-elastic liquids efficiently
|
Low possibility for Radial mixing
|
Anchor
|
Highly used in Pharma Industry for Several Operations
|
Increase possible heat transfer rate in reactors, from reactor heat transfer surface to Mass.
|
Required high Efficiency Gearbox,
Required high Power. |
Gate
|
Highly used for blending Operations
|
Provides efficient Mixing and agitation control,
Can handle Pseudo-plastic liquids. |
Not preferred when both liquids and gases combine involves
|
Propeller
|
Suitable for GLR’s, ANFD’s, can handle Corrosive materials with Glass lining.
|
Will increase the homogeneity,Can be used in two different patterns for drying and pressing.
|
* Need to be operated at high speed to avoid solid settlings in reactors.
Need to be operated at low speeds in drying operations |
