Brief Introduction of Various Powder Mixer

When a factory is built at the very beginning, blenders and mixers usually are the first few items on the owners’ shopping list. However, if you Google them online, you will find various models for blenders and mixers. There are Conical Screw Mixer, Horizontal Ribbon Mixer, Plough Shear Mixer, Double Shaft Paddle Mixer, Continuous Mixer, Single Shaft Paddle Mixer, Paste Mixer, Liquid Mixer and Even Sanitary Conical Mixer. What are the differences from all those different models? Which one is the most suitable for your business? As the experts in the mixing and blending industry, Vortex Mixing Technology (Vortex MT) is happy to help you make the smart mixer selections by illustrating the differences among different mixers.

Before we start the brief introductions of blenders and mixers, please keep in mind of the factors that will help determine the final mixer selection:
1. what are the objectives of your blending and mixing?
2. how much space do you have for the blenders in the plant?
3. how much budget do you have in mind for the mixers?
4. how soon do you want to get the blenders start working?
conical screw mixer structure

We start our mixing journey with Conical Screw Mixer which treats the product mixture gently with high accuracy. The mixing speed for conical screw mixer is slower compared to other mixers which helps avoid material distortion. Therefore, there is little damage to the raw material. That is why conical screw mixer is the right choice for fragile materials. The other advantage of conical screw mixer is the residue free material discharge. Minimum product retention is essential for some industries such as Chemical and Pesticides. Last but not least, conical screw mixer does not require high power assumption to give a great performance with high efficiency.


  1. No damage to the raw materials
  2. Complete Discharge with no leftover
  3. Low Power consumption and large output

Working Principles:
Double screw conical mixer rotated around its axes by right of two internal asymmetric spirals which is installed on the cantilever. Meanwhile, the rotational force from the cantilever drives two spirals doing revolution around conical chamber axle wire.

Double screw conical mixer has 4 direction forces:
1. two inner asymmetric spirals upgrade materials by rotation
2. tumbler rotates the materials in circles with low speed
3. spirals’ rotation and revolution make materials absorbed while spreading them around
4. two flows of materials create a downward material flow by upward and then down to center which fills the bottom gap and form a convective circulation.

Conical mixer is widely used in chemical, agriculture, dyes, food, pigment, battery material, rare earth, Rubber etc. It can mix power with power, granule with granule, etc.,
1. conical chamber can achieve a demanding request to discharge without residual material.
2. no damaged for fragile materials because of its soft mixing speed.
3. better mating reaction under low power cost.

Through design, the double screw conical mixer can adapt to all kinds of production line and cooperate with other types of equipment including the conveying equipment, storage facility, feeding equipment, weights system, packing machine, and screening machinery to complete the automation production requirements.

In the mixing process, the standard mixer does not always solve the problems. Mixers need to be customized according to the different cases. The cases are as below:
1. hard agglomerated material larger than 2mm is contained in the raw material
2. bulk density of the raw material bigger than 2kg/L
3. powder size larger than 500 mesh
4. dry power with high moisture content like damped, hygroscopic or adhesive
5. mixer needed to heat up to 120 degrees Celsius
6. materials with special chemical property: exothermic, vaporization, inflammable, explosive, adhesive.
7. the specific gravity ratio of two kinds of material is beyond 1:20, and the size ration is beyond 1:100
8. mixer need to be vacuum or in negative pressure state
9. fill compressed air to the mixed barrel and keep the pressure
10. severe abrasion to mixer because of the size and the hardness of the raw material
11. Material is not allowed to contact with the metal surface during mixing process
12. Heavy duty (loading material into mixer before turning on it) is required

To conclude, although mixer has a strong ability to adapt to the different materials, in the following cases, our mixer is not applied, material with no flow ability, like paste and solid oil, material with a formula of 1:1000 or lower than that. Material can become agglomeration and harden in a short time, material without a stable chemical property like explosive.

Factory Space Consideration:
After review all the technique specifications, if you find that conical screw mixer is the right choice for your product line, think about the plant space before you put it into your purchase basket. Conical screw mixer requires enough space, especially the height of your plant. For some factories, it is not high enough for the conical screw mixer to be installed, thus build a new factory would not be the most economic solution to this problem. You can choose ribbon mixer in this case.

Cost Performance:
Since you have chosen the proper mixer for your product line, you will need to purchase it at a reasonable price with great performance. For startups, the budget is usually tight. That is why we recommend you to get inquires from different companies. In the process of communication, you will find that the service they have offered in this part varies a lot and you have to judge whether they can be trusted based on the impression you have got. What is more, you will find the price offers for the same mixer are way too far away from each other. As the expert in mixing and blending, we recommend you to choose the higher offer from the lower parts. For example, you get the price offer of USD 100000 from Ross and you get another offer from China unknown factory at the price of USD 10000. It can really confuse you whether they are talking about the same mixer. In addition, you get another professional price offer from Vortex Mixing Technology at the price of USD 25,000. This is the right one you should choose. On one hand, they have the price advantage: you may get it at a quarter of 100.000. On the other hand, they are really professional and the after service is amazing. Feel free to contact us for more information relating to mixer inquires [email protected]

Time Frame:
A lot new clients of Vortex Mixing Technology are concerned with the time frame for their mixers. I have to say, there is no need at all as we are armed with a number of professional team workers who can produce hundreds of mixers within 1 month. We will inform you of the delivery time before we sign the contract and we can guarantee that your mixer will be ready in time for your successful career.

I wish you have got the general idea of conical screw mixer and can tell if this is the right mixer for your product line. Feel free to contact us if you have any questions. If this is not the right one for you, check out if ribbon mixer is the right choice for you.
