The Working Principle of Powder Mixer Machine
The types of pharmaceutical or industrial mixer machines are divided into three main categories based on their geometrical shapes:
1.V-type mixer machine
2.Eccentric cone design mixer machines
3.Ribbon mixer machines
Of course, there are other designs too; however, their working principle is almost the same.
· The Working Principle of V-type Mixer Machine
The working principle of a V-type mixer machine is simple. Here is how it works:
It is made of two V-shells as you can see in the image above. They may be of the same size or slightly different.
The equipment depends on mechanical transmission of material within the shells.
Fill the V-shells with the specified amount of material.
Key in parameters via the control panel
Switch on the machine and allow it to rotate at a specified speed and time
As the V-shells move through an angle of 360°, its content will move back and forth, hence a homogenous product.
Remember, even when you change the V-shells like in the case of the lab models, the working principle will still remain the same.
· The Working Principle of Eccentric Cone Design Mixer
How an eccentric cone design mixer is similar to that of the V-type mixer machines. That is, the working principle of this mixer machine involves:
Charge the material into the container and close
Assign appropriate parameters – mixing time and speed
Switch on the machine to drive the motor
Your machine will mix and ultimately stop after the specified mixing time.
You can transfer the content of the mixer bin to another container for further processing or packaging.
As you can see, this is a simple process that you can accomplish easily. However, the design of this equipment plays a critical role in the mixing efficiency.
· The Working Principe of Ribbon Mixer
Like in other machines I have discussed so far, the working principle of horizontal ribbon mixer aims to ensure homogeneous mixing within a short period of time.
So, how is this possible?
1.Its design aim to mix free-flowing raw material (powder or granules) within the U-shaped trough
2.By switching on the electric motor, it begins to turn the horizontal agitators.
3.The agitator has balanced inner and outer helical ribbons that force the material to flow in both radial and axial directions at the same time. That is, the outer ribbon will move the material in one direction as the outer ribbon moves material in the opposite direction.
4.Alternatively, there are other designs of horizontal ribbon mixers where; the outside screws collect and move material from the sides of the horizontal trough to the center. On the other hand, the inner screws move material from the center of the trough to the sides.
5.Still, the principle of operation remains the same.
In both cases, this is a continuous process that ensures homogeneous mixing within a short time cycle. In most cases, the helical agitators (components of the ribbon agitator) rotate at 300 rpm.
Clearly, you can see that, the ribbon mixer, eccentric cone design mixer and V-type mixes use different mechanisms to ensure a thorough material blend within minutes. Normally, I do advise all clients to understand their material processing needs and standards before purchasing any of these mixing machines.
Key Applications of Powder Mixer Machines
Mixer machines play an integral role in material processing. Choosing a specific type of machine will depend on the specific task at hand.
Thus, depending on the design, you may use machines designed for R&D, food processing, nutriceutical, pharmaceutical, chemical processing, laboratories, etc.
Depending on the design of the industrial or pharmaceutical mixer machine, you can process the following combination of materials:
1.Granules and granules
2.Granules and powder
3.Powder and powder
In most cases, your granule or powder mixer machine can process dry material. However, there are those special designs that can process both wet and dry materials.
