- 2. • Agitator : An agitator is something which is used to stir liquid or mixture of liquids. • What it can do ? : It can be used in various operations, in a pharma industry it can be used in multiple operations like reactions, work up's, drying, filtration, etc. • Agitation : It refers to the induced motion of a “homogenous” material in a specified way.

- 4. Application of Paddle • Mixing of Solids. • Slurry Mixing. • Used during Crystals forming phase during Super saturated Cooling. Application of Turbine • Liquids and Gas reactions. • Highly used during Reaction and Extraction Operations.
- 5. Application of Screw type Agitator • Have to use in addition to other agitators. • Mostly used in Food processing. Application of Helical Blade • Most Probably used in Paint industry. • They operate with minimal clearance at the vessel wall and provide axial flow at low speed.
- 6. Application of Anchor • Highly used in Pharma Industry for Several Operations. • The anchor agitator/impeller is close clearance, radial flow impeller used for mixing of viscous liquids.
- 7. Application of Gate • Highly used for blending Operations. • They are used in wide shallow tanks and for materials of high viscosity when low shear is adequate Application of Propeller • Suitable for GLR's, ANFD's, can handle Corrosive materials with Glass lining.
- 9. Process Considerations • This requires matching the your process requirements with the correct impeller design. Based on your requirements in terms of product, blend/residence time, and rheology, we match the impeller type, vessel design, power, and speed, to arrive at an optimum impeller selection. Power Considerations • Once the process aspects of the mixer design are finalized, we’ll need to optimize a final design that uses power efficiently. This could mean altering the D/T (impeller to Tank Ø) ratio to produce the
- 10. Mechanical Design • It should be designed to have a mechanical life of 20 years. The key to efficient mechanical design is understanding the forces acting on the mixer. Mixers are dynamic machines with fluctuating loads and forces. Shafts are usually overhung with no lower support. same process result at reduced power. The price to pay will be torque, which could require larger gearboxes, using lower power. This is a trade-off between operating cost and capital cost, often requiring input from the customer.
