What is agitator mixer?
An Agitator is a machine used in a tank for mixing various process media together. Media include all liquid types, gases & solids (such as salts, powders, granules etc). In summary, it works by rotating an impeller to impart energy to the media which interact and mix.
What is the difference between agitator and mixer?
Is there a difference? Technically speaking, an agitator is a machine with the purpose of moving liquid. In the industrial world the terms agitator and mixer are used interchangeably and essentially mean the same thing. So, the short answer: No, there is effectively no difference.
How do I choose an agitator?
Selection Criteria of Industrial Agitators The viscosity of the bulk. Exact function required (blending, dissolving, dispersion, heat exchange, chemical reaction, crystallization, emulsification, suspension, etc). The mixing cycle (batch size, the time required for agitation, material addition sequence, etc)
What are the different types of agitators?
Types of Agitators
- Turbine Agitators.
- Paddle Agitators.
- Anchor Agitators.
- Propeller Agitators.
- Helical Agitators.
What do agitators do?
An agitator is a device or mechanism to put something into motion by shaking or stirring. There are several types of agitation machines, including washing machine agitators (which rotate back and forth) and magnetic agitators (which contain a magnetic bar rotating in a magnetic field).
What is the use of agitator in drawing?
Agitator to stir the paint before use. Opaque colour tone. Smooth matte finish.
Which of the following is kind of agitator?
Types of agitators models, application and comparison:
| Agitator models | Application |
|---|---|
| Impeller type | Emulsion preparations |
| Turbine agitator Straight blade Pitched blade Vaned disk Curved blade Hydrofoil Impeller | Liquid and gas reactions |
| Slotted rotary Rotating disk | Powders and cosmetics |
| Screw Screw in cone | Food and snack processing |
What is agitator in fermenter?
Agitators have been used in fermenters for many years. The functions of the mixer in fermentation processes requiring dispersion of air or oxygen in a broth are that they: Provide uniform dispersion of gas bubbles. Produce small gas bubbles by shearing the inlet gas with fluid velocity gradients.
What are mechanical agitators?
Agitators are used in liquid systems to suspend solids and maintain homogeneous mixture throughout the system. Park¬Process’ mechanical agitator is driven by an explosion-proof motor coupled to a gear box that drives the impeller shaft.
What should be the maximum number of baffles in the design of agitators?
Number of baffles = 3 to 4 (4 is ideal, but 3 will result in sufficient mixing). Adding any more than 4 baffles will not result in any significant mixing improvement.
Do agitators damage clothes?
One of the drawbacks commonly associated with agitators are they are too aggressive with the way they launder clothes. While agitators are effective, they are also effective in causing damage to clothes in the form of tears and rips.
Are impellers better than agitators?
Impeller machines are potentially less damaging to clothes, but because of the gentler motion, they may not clean clothes as effectively as agitator machines. Agitators are relatively brutal with clothes, but their twisting and turning tends to remove dirt quickly and completely.
Which is the best type of agitator for mixing?
Helical Agitators: These agitators have blades with a twisting mechanism, just like the threads of a screw. The curve results in strenuous movement of the fluid to be agitated. Spiral mixers are best suited for mixing viscous liquids. top entry mixer is designed for stirring low viscosity material or heavy material.
How to program for design and drawing of agitator?
Program for Design and Drawing of Agitator / Mixer asks for size of vessel and properties of liquid. You can decide proportion of Diameter of Impeller to Diameter of Vessel, and expected Reynold’s Number. Based on the impeller selected, Program for Design and Drawing of Agitator / Mixer will indicate Mixing number and Power number.
What are the different types of agitators in India?
Side Entry Mixer, heat exchangers, high speed dispersers, Hydraulic High speed disperser reactor pressure vessels and Agitator Stirrer in India. Anchor Agitators: Anchor Agitators consists of a shaft and an anchored propeller that can be mounted centrally or at an angle.
How to calculate the number of agitators in a tank?
There can be many number of agitators connected to a shaft, and it can be calculated as Number of agitators= (Maximum liquid height x specific gravity) / Diameter of tank. Gap between two Agitators= Liquid height / (Number of impellers – 0.5). Basic Design Equations for a Vertical Vessel and Agitator:
