Double Motion Mixer

The double motion mixer is an advanced mixing machine which is used to mix various types of materials, including solids, liquids, and powders. The barrel turn around while full scale blade run independently and in addition, the barrel and blades turn around in different speed and different directions.

Description Of Double Motion Mixer

The double motion mixer employs advanced double motion superimposing mixing technology to achieve two major functions of gravity diffusion mixing and forced shear mixing in one device. It achieves macroscopic uniformity by allowing the powder to roll up and down, flow from left to right, and diffuse uniformly; it also achieves microscopic fine forced mixing by repeatedly interweaving and shearing particles at multiple levels and directions. Therefore, the mixing uniformity can reach the ideal state of both macroscopic and ultra-fine uniformity.

Advantage Of Double Motion Mixer

High Mixing Uniformity

Utilizing advanced dual-motion superimposing mixing technology, the mixer achieves both macroscopic uniformity—allowing the powder to roll up and down and diffuse evenly from left to right—and microscopic fine mixing through repeated multi-level, multi-directional interpenetration and shearing between particles. Thus, the mixing uniformity can reach the ideal state of both macroscopic and ultra-fine uniformity.

High Mixing Efficiency

This is also due to the advanced principles of dual-motion superimposing mixing, where both movements occur simultaneously within the same unit of time. This not only doubles the mixing efficiency but also effectively promotes mixing interactions, making the mixing process more efficient. Therefore, dual-motion mixers save 60% of the time compared to traditional mixers.

Equipment Loading Rate up to 80%

In dual-motion mixers, the main mixing work is carried out by the internal motion of the spiral blades, allowing for minimal remaining space in the mixing drum. Therefore, even with a high loading rate, the equipment can still efficiently complete mixing tasks. Consequently, dual-motion mixers offer an increased loading capacity of over 50% compared to traditional mixers.

Minimal Alteration of Powder Appearance after Uniform Mixing

Many industries require minimal alteration in the shape and size of powders after mixing to achieve precise control over the overall process. Dual-motion mixers excel in this aspect.
This is because the core principle of dual-motion mixers involves low-speed shearing mixing in multiple layers and directions within the low-speed flowing powder. The mixing motion is smooth and orderly, devoid of powder impact or high-speed impact. Coupled with significantly shortened mixing times, this preserves the original appearance of the powder.

Meeting the Requirements of Fine Mixing for High-tech and Ultrafine Materials

A significant characteristic of high-tech and ultrafine materials is their minuteness, sometimes even reaching the nanometer scale, where gravity loses its binding force, making mixing challenging. Intense mechanical energy in traditional mixers can transfer energy to the powder, causing various reactive behaviors such as floating, adsorption, and repulsion, thus complicating the mixing process.
The core principle of dual-motion mixers involves low-speed shearing mixing within the low-speed flowing powder. Its minimal mechanical impact, friction, and energy significantly inhibit the activities of ultrafine powder, allowing for smooth mixing.

Effective Solution to the Mixing Difficulty of Light and Heavy Powders

In traditional mixers, the uniform mixing of light and heavy powders poses a typical challenge due to their weight differences, with light powders often suspending over the main body of the powder, making it difficult to integrate them, even with prolonged mixing.
Double movement mixers effectively address this challenge. With the container and internal blades rotating in the same direction and at an accelerated speed, the container and blades entrap and incorporate the floating light powder into the main heavy powder, ensuring uniform mixing.

Effective Solution to the Mixing Difficulty of Trace Elements

The poor mixing ability of traditional mixers restricts the uniform mixing of trace elements, often necessitating complex mixing methods such as manual equal batch feeding to overcome equipment deficiencies. In contrast, the excellent mixing capability of dual-motion superimposing mixers allows for complete and uniform mixing of trace elements in one step, saving time, labor, and ensuring reliability.
In industries such as food additives and pharmaceuticals, where powder flow ability is generally poor, over half of powder mixing employs the equal incremental method for trace element mixing, imposing a significant burden on enterprises. Adopting double motion mixers can save a considerable amount of manpower, resources, and valuable time.

Specification Of Double Motion Mixer

Working Principle Of Double Motion Mixer

The mixing principle of the double motion mixer is two motion superposition mixing:
1. The operation mode of the material barrel is that the center of gravity of the powder remains unchanged and the powder rolls and rotates continuously at a uniform speed.
2. The blades are stirred between the already moving powders, so the stirring force required is small and the energy consumption is very small.
The double motion mixer has a high mixing efficiency, and the mixing time required is less than 50% of the mixing time required by traditional mixers (such as V-type models, three-dimensional models, double cone models, etc.). 90% of the energy consumption of traditional gravity diffusion mixers is spent on lifting work on materials, so the energy consumption is very large. Normally the motor used by the double motion mixer with the same weight is half the power specification of the motor used by the traditional gravity diffusion mixer.

Double Motion Mixer FAQ

  • Requirements for Mixing Equipment

    Considering the characteristics of the powder, the equipment should possess: good mixing uniformity, no dead corners, high mixing efficiency, low power consumption, etc. The mixing equipment should not alter the physical properties of the powder, such as density, average particle size, and particle surface shape. Furthermore, the mixing equipment should operate safely, be easy to operate, save energy, and reduce labor costs.

  • Selection Principles for Mixing Equipment

    1. Choose ordinary models like V-shaped mixers for easy mixing tasks; for challenging tasks, opt for high-performance mixers.

    2. Use forced shear mixing machines for powders with poor flowability.

    3. For powders that are difficult to mix, such as ultra-light or ultrafine powders, choose composite mixers that combine gravity diffusion with forced agitation.
  • What is the implementation methods of powder mixing

    1.Gravity Convection Diffusion Mixing Method
    This method continuously raises the center of gravity of the powder, utilizing gravity to force the powder to undergo repeated flow, diffusion, collision, folding, and other movements. Its purpose is to macroscopically intermix and infiltrate powder particles, thereby achieving uniform mixing.


    2.Forced Shear Mixing Method
    Utilizing the motion of the stirring blades within the container to forcefully stir and shear the powder repeatedly. Its purpose is to microscopically break up the adjacent relationships between powder particles, allowing them to move and exchange fully, achieving uniform powder mixing.

     


     



  • What is the principles of powder mixing

    1.Diffusion Mixing: Small-scale layer-by-layer diffusion movement of powder particles. Under external forces, separated powder particles move to continuously emerging new layers, allowing the components of the powder to diffuse and achieve uniform distribution within a local range. The conditions for diffusion mixing are: powder particles distributed on continuously emerging new layers.

    2.Convection Mixing: Large-scale random movement of powder particles. Under external forces, powder particles undergo fluid-like motion, moving from one point to another within the material, enabling powder particles to convect and achieve uniform distribution over a large range.

    3.Shear Mixing: Internal shearing of powder material masses. Under external forces, powder particles experience mutual slipping, forming shear planes, continuously shearing local powder to achieve uniform distribution.
