The Mixer is a machine and equipment that uses mechanical force and gravity to mix two or more materials. It can also increase the surface area of the material contacting the barrel, and accelerate the chemical reaction due to friction, speed, time …etc and accelerate physical changes.
Types of Mixers
There are two types of mixers if they are classified by mechanism. One is that the barrel is fixed, and there are various rotating stirring rods in the barrel, such as spiral blades, stirring scrapers, stirring fins, stirring shovel, stirring coulter, stirring rake... etc. The second is that the shaft is erected with a torsion rod to be fixed and the barrel rotates.
If classified by material type, mixers can be divided into four categories:
- Thermoplastic Material Mixer
Mainly used for the mixing of thermoplastic materials, plastics, rubber...and additives, powder, granular, flake or solid materials. Most of the products in this part are mixed with spiral lifting materials (Pulian BV series) or The erecting blade rotates along the edge of the barrel wall, pushing part of the material into the center to varying degrees. The other part of the material is thrown out, so that the material on the circumference is constantly updated and diffused. The materials on both sides also merge to the center through the left-hand and right-hand relationship to form a ∞-character staggered cycle, so that the material is The center, the top and bottom are staggered, and the left and right are staggered, so that the materials can be uniformly mixed in a short time, and the mixing effect is the best (Pulian BU series).
This series of mixers are highly adaptable to various materials, and will not produce overheating. They will not grind or crush particles. They will not separate when the particle size is relatively large. It is extremely versatile. Best mixing equipment.
- Gas and Low Viscosity Liquid Mixer
It is characterized by simple structure, no rotating parts, low energy consumption, low maintenance, mainly through medium pressure or high pressure gas spray in the fixed container, so that the material swirls and sprays around the inside of the container, resulting in turbulent mixing effect.
- Medium and High Viscosity Liquid and Paste Mixer
When the stirring shaft is moving and rotating, it must have a strong effect of shearing the material. Continuously cutting or cutting the liquid and paste will cause countless split vortices to force the material to disperse to achieve a uniform mixing effect. If the viscosity of the liquid is not high It can be completed in a shorter time, if the viscosity is too high, a longer mixing time is required.
- Powder, Granular and Liquid Incompatible Mixer
For liquids or solids with different densities and ingredients that are incompatible with each other, the stirring rod must play a shearing effect, violently cut the dense materials into small pieces, and evenly distribute them in the container, and the stirring speed must also be greater than the settling speed of the material , It will not cause the uneven mixing phenomenon due to suspension or precipitation.
