The commonly used mixers are divided into four categories: gas and low viscosity mixers, medium high viscosity and paste mixing machines, thermoplastic material mixers, and powder and granular solid material mixing machines.
The characteristics of gas and low viscosity mixers are simple structure, no rotating parts, low maintenance, and low energy consumption. This type of mixing machinery is divided into four types: air flow mixing, pipeline mixing, jet mixing, and forced circulation mixing.
The main components of the mixer are made of wear-resistant alloy materials, including high-speed mixing, mixing fins, wear-resistant lining plates, mixing arms, mixing shovels, planetary shovels, mixing plows, mixing bars, mixing rakes and other second-hand heat transfer equipment; Evaporator, rising film evaporator, falling film evaporator, concentration evaporator, single effect evaporator, double effect evaporator, three effect evaporator, four effect evaporator, thin film evaporator, thin film evaporator, scraper evaporator, spherical concentration evaporator, stainless steel tube condenser, spiral heat exchanger, plate heat exchanger, various material heat exchanger condenser, etc. Conducting heat transfer, processing second-hand high-temperature bag filter, selling multiple second-hand bag pulse dust collectors; Selling MC pulse bag filter, used bag filter, used Flumes high-temperature resistant dust collector, single machine bag filter
The mixing machinery of medium and high viscosity and paste like substances generally has strong shear effects.
Thermoplastic material mixing machinery is mainly used for mixing thermoplastic materials (such as rubber and plastic) with additives; Powder and granular solid material mixing machinery is mostly operated intermittently, including machinery that also has mixing and grinding functions, such as wheel rollers.
The moving parts of a mechanical mixer also generate shear forces when passing through the wall and various fixed components installed in the container. These shear forces can cause many local eddy currents to diffuse.
For those with different densities, compositions, and immiscibility, the shear effect and strong turbulence generated by stirring will tear the high-density ones into small droplets and evenly disperse them into the main body. [1]

(7) The self rotation and revolution of this machine are both completed by a set of motors and cycloidal pin transmission reducers.
3、 Working principle
(1) Due to the revolution of the double helix, the powder particles move around the cone.
(2) Due to the self propagation of the spiral blades, the powder is discharged radially towards the cone.
(3) The powder flows upwards from the bottom of the cone and onto the outer surface of the spiral for material mixing.
(4) The downward flow of powder particles caused by the spiral rotation is precisely due to the combination of the revolution and rotation of the spiral in the mixer, forming four forms of powder flow: convection, shear, diffusion, and infiltration. Therefore, the powder can quickly achieve uniform mixing in the mixer. [2]
Ribbon Mixer
The dual axis screw belt mixer is used to mix dry and powdery materials, achieving uniform mixing. The material inside the mixer is subjected to the motion of two rotors moving in opposite directions, undergoing complex movements. The dual axis blade carries the animal material along the machine slot in both clockwise and counterclockwise directions, with the material near the axis as the axis and pushing from the inside to both sides in the axial direction. The outer spiral drives the material near the cylinder wall as the axis and pushes from both sides to the inside in the axial direction, resulting in convective circulation and shear infiltration of the material cylinder, completing rapid and uniform mixing of the material in a short period of time
Product Features:
1. Adopting a U-shaped barrel structure, it operates smoothly, mixes evenly, discharges cleanly, and has a wide range of applications.
2. Adopting inner and outer double-layer spiral belts for staggered back and forth mixing, the mixing speed is fast and the uniformity is high
3. The bearings are located at both ends of the mixer, making it difficult for materials to enter and resulting in a low maintenance rate.
4. The screw conveyor is convenient for feeding, with the feeding port level with the ground, making feeding effortless and convenient.
5. The internal structure and overall design materials have been certified by *.
Working principle of dual axis screw belt mixer:
This machine consists of two parts: feeding and mixing.
1. Feeding section: The material enters from the feeding hopper and is mixed into the mixing drum through the spiral blades in the mixer.
2. Mixing section: When the material enters the mixing drum for back and forth staggered movement, the mixing effect is good. [3]
Spiral belt mixer
3D mixer
The working principle of the triple mixer is not exactly the same as that of the rotary mixer. It performs complex movements such as translation, rotation, and rock motion in the three-dimensional space of the cube, causing the material to be in a "flow translation inverted falling" state inside the mixing cylinder, which is called the TURBULA state; Generate an alternating pulse that continuously pushes the material, and the turbulence generated by the motion has a changing energy gradient, so that each particle in the mixed material has an impossible motion state. Each particle constantly changes its position in the diffusion of motion, producing a satisfactory mixing effect.
The 3D mixer consists of a machine base, drive, 3D motion mechanism, mixing cylinder, and electrical control. The mixing cylinder, which is directly connected to the material, is made of high-quality stainless steel material and polished with precision.
Series 3D is a novel material mixer widely used in industries such as pharmaceuticals, chemicals, food, light industry, and research institutions. This machine can uniformly mix powdered or granular materials with good flowability, achieving the desired effect.

Processing information of double helix mixerWorking Principle:
The double cone vacuum drying mixer is a rotating tank with a double cone shape. Inside the tank, under vacuum, steam or hot water is directed into the jacket for heating, and the heat passes through the wet material. The water vapor evaporated from wet materials after absorbing heat is pumped out through a vacuum exhaust pipe by a vacuum pump. Due to the vacuum state of the tank body and the continuous rotation of the tank causing the material to move up and down, inside and outside, the drying speed and efficiency of the material are accelerated, achieving the goal of uniform drying.
Purpose:
This machine is used for vacuum drying and mixing of powder and granular materials in industries such as food and chemical, especially suitable for materials with the following requirements:
1. Cannot accept high temperature thermosensitive materials;
2. Easy to oxidize and hazardous materials;
3. Need to recycle solvents and organic materials;
4. Require materials with extremely low residual volatile matter content;
select
Many users choose the existing vertical cone mixing equipment in China for powder and powder mixing equipment. However, experts suggest that due to the many disadvantages and high maintenance rate of vertical cone mixers, a mixer should be selected when mixing powder/powder or granular materials. This equipment has high mixing efficiency, good mixing, short discharge time, and low residual amount. However, when choosing and using a mixer, the following points should be noted:
1. Select a horizontal mixer based on daily production volume. Due to the processing time of each batch of materials in the mixer being about 10 minutes, plus the time for discharging and feeding, the processing time for each batch of materials can be calculated as 15 minutes. Therefore, 4 batches of materials can be processed continuously in 1 hour. If a mixer with a processing capacity of 100 kilograms per batch is selected, it can process 400 kilograms per hour. Users can choose a mixer according to their own needs.
2. According to the working principle of the spiral belt mixer, the ability of the double spiral belt used for stirring and mixing materials in opposite directions should be basically consistent. Due to the fact that the pitch of the inner spiral belt should be smaller than that of the outer spiral belt, in order to achieve consistent material capacity, the pitch of the inner spiral belt should be smaller than that of the outer spiral belt, while the width should be larger than that of the outer spiral belt, otherwise it will cause the material to concentrate in one direction. Therefore, it is important to pay attention to this when choosing a mixer.
3. According to the design principle, the gap between the spiral belt and the shell in the spiral belt mixer can be 4-10mm, and the material can be forcefully driven to participate in the mixing process. However, due to differences in particle size and material coefficients, the mixing time of various components of the material may vary, resulting in unevenness of the product. Some manufacturers have realized this and made improvements to their products. One is to pay attention to the machining accuracy, so that the bottom gap is about 3 millimeters; Another way is to make the position between the spindle and the housing adjustable, and adjust the gap between the spiral belt and the housing according to the wear amount. When choosing a mixer, these two forms of products should be selected.
4. Pay attention to the discharge when choosing a spiral belt mixer. It is necessary to communicate with suppliers in a timely manner to choose a valve form that is suitable for one's own process, and not to choose a side outlet discharge form. The reason is that when the mixer completes stirring and mixing within the specified time, it can ensure the uniformity of the material by releasing it all at once; If the side spiral belt is gradually emptied, it will delay time and fail to achieve the expected productivity. Secondly, the material has already reached uniformity, but stirring will cause material segregation and loss of uniformity, thus losing the significance of choosing a mixer.
5. Pay attention to the order of feeding when using a mixer. Generally, large materials, such as corn meal, soybean meal, etc., are put in first, and then group materials, such as premix, are put in. Note that the premix should not be fed by a screw machine, but should be fed by a disposable tipping bucket or manually, in order to avoid the segregation and loss of effective ingredients in the premix.
6. When using a mixer, it should be fed in batches after the mixer is started. Do not stop the machine when the mixing is completed and the material is discharged before mixing another batch. If starting after full load, it will cause the power distance to be too large and burn out the motor.
Choosing a suitable mixer and using it properly will result in a noticeable mixture and quickly reflect positive effects in production. If the technology of self mixing and blending can be further developed, it can greatly reduce material costs and thus increase profits
