Types of Agitators

Paddle Agitators: Paddle Agitators is one of the most important types of agitators whose blades reach the tank wall. A Paddle Agitators is used where a uniform laminar fluid is required. It implements heavy-duty mixing and proves to be an excellent device for low speed. Its simple structure makes the machine easy to manage.

Anchor Agitators: Anchor Agitators consists of a shaft and an anchored propeller that can be mounted centrally or at an angle. It is mainly used in reactors.

Radial Propeller Agitators: The radial agitator consists of a propeller similar to a marine propeller. They consist of two to four blades that move in a screw-like manner, pushing the material parallel to the shaft for agitation.

Propeller Agitators: It is an axial flow high-performance mixer consisting of three blades mounted on the main shaft. They are ideal for mixing low viscosity and medium viscosity fluids and improving uniformity. Propeller agitators are popular for simple mixing jobs.

Turbine Agitators: Turbine Agitators are widely used to perform all types of mixing operations and to handle fluid and liquid or gas reactions of various viscosities. Its ability to produce high radial flow facilitates the dispersion operation.

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.

Slurry Mixing Agitator Manufacturer in Pune| Basic Guidelines for Designing Agitator

Slurry Mixing Agitator

The main technological facilities of the Alumina refinery include various types of stationery and rotary processing equipment such as mills, conveyors, ball mills, tanks, pumps, piping, agitators, evaporators, heat exchangers, alkalis, filters, and calciners. The majority of the alumina refinery's processing plants are tailor-made for the plant's needs.

Equipment designers and process experts believe that the design of agitators to mix slurry with the desired degree of agitation is considered a complicated and delicate issue. In the previous publication, this post explained the terminology used in the construction of agitators for mixing sludge.

Given the need for suitable agitators for the alumina refinery, it was essential to briefly describe the mixing process and to develop the basic guidelines and associated parameters for driving calculations for slurry mixers suitable for the various conditions. treatment in the alumina refinery.

MIXING PROCESSES

The alumina refinery can be roughly divided into two main treatment areas -
(i) red zone and
(ii) white area

In the red section of the alumina refinery, the main tasks of agitators for such tanks are:

• Keep the solids in suspension
• Homogeneity of slurry

The agitator components primarily comprise a turbine, a shaft, a transmission and a drive motor capable of meeting the process requirements. The mixing process to hold the solids in suspension is known as the bottom suspension. This process keeps the solid particles just above the bottom of the container and prevents sedimentation of the solids.

The other method used for the homogeneity of the suspension is generally known as a solid tank suspension. In the case of a solid tank suspension device, the agitation level is close to 10. Therefore, the agitator always moves the bottom solids of the tank to the upper level, which allows it to be transferred to the tank. the next line tank.

 
Due to the actual properties of alumina hydrate or the size of very large capacity tanks, the following additional challenges for the designer in the development of agitators for use in the white zone of the alumina refinery arise : 

• The low shear rate of selected fuels to avoid abrasion of solid crystals
• Low energy consumption

The typical physical properties of sludge components are given below -

• The density of the aluminate liquor: 1.23 - 1.29 (liquid)
• The density of alumina hydrate: 2.42 (solids)
• bauxite: 2.58 (solids)
• Bauxite residue (red mud): 2.3 (solids)

Types of agitators/mixers

There are three types of agitators that are used in alumina refineries - 

1. Top entry mixer
2. Side entry mixer

In the alumina refinery, top entry agitators are preferred over other options.

DESIGN ELEMENTS OF MIXER

The following are the main elements of the mixer design -

• impellers
• waves
• Training set
• process conditions
• Properties of the wheel performance
• Mechanical construction

FACTORS AFFECTING ENERGY CONSUMPTION

The energy consumption for stirring/mixing is influenced by the following main factors:

1. Specific gravity
2. Viscosity
3. Wheel type
4. The diameter of the wheel
5. Wheel position
6. Writing speed
7. Baffles in the tank

The capacity of the turbine and the capacity of the agitator pump are calculated using the following mathematical relationships:
Power of the wheel, P = Np x N3 x D5
Pumping capacity of the turbine, Q = Nq x N x D3

MECHANICAL DESIGN BY IMPELLERS

The wheel is the most important element of the mixer. Only the turbine generates the required process result by converting the rotational energy of the shaft into the required flow and shear ratios. The efficiency of the process requires the adaptation of the properties of the wheel to the requirements of the process. The ideal wheel for flow-controlled applications must have the following basic features:

- Low power - Np
- High flow - Nq
- In weightlessness
- Low fluid forces
- Cost-effective

Therefore, agitator manufacturers must take reasonable precautions when selecting/designing turbines, taking into account the critical aspects above, as the coefficient of performance and flow rate depend on the type of wheel.
