Type of powder mixing machine
The mixer machine is a mechanical device that uses mechanical force and gravity to evenly mix two or more materials. During the mixing process, it can also increase the contact surface area of the materials to promote chemical reactions;it can also accelerate physical changes.
Commonly used mixers are divided into Three-dimensional Mixing Machine, V series Mixing Machine, Dual Cone Mixing Machine, and Horizontal Ribbon-spiral Mixing Machine
Dual Cone Mixing Machine
I. Main uses:
Dual Cone Mixing Machine is a new type of high-efficiency, high-precision particle mixing equipment. It is widely used in the mixing of various powder particles in the chemical, pesticide, dye, medicine, food, feed, petroleum, metallurgy and mining industries.
II. Main features
(1) Advanced structure, easy operation, safe and reliable operation.
(2) Fast mixing speed and uniform quality. The double spirals of this machine are arranged asymmetrically, with one large and one small, which expands the mixing range, so it is more suitable for mixing materials with different specific gravities.
(3) Significant energy saving effect. Compared with the drum mixer, the energy consumption of this machine is only one-tenth of that of the drum mixer.
(4) The wear and pressure on the granular materials are minimal, and there is no overheating reaction when mixing heat-sensitive materials.
(5) The mixed preparation is stable, and there is no stratification or segregation.
(6) The machine is sealed and dust-free, easy to operate, easy to maintain, and has a long service life. In addition, according to user requirements, the cone can be made into a pressure vessel for pressurization or vacuum operation.
(7) The rotation and revolution of this machine are completed by a set of motors and cycloidal pin reducers.
III. Working principle
(1) Due to the revolution of the double helix, the powder particles move around along the wall of the cone.
(2) Due to the rotation of the spiral blades, the powder is discharged radially toward the center of the cone.
(3) The powder rises from the bottom of the cone and is discharged on the outer peripheral surface of the spiral to mix the materials.
(4) The downward flow of the powder particles caused by the self-rotation of the spiral is due to the combination of the revolution and self-rotation of the spiral in the mixer, forming four flow forms of the powder: convection, shear, diffusion, and infiltration. Therefore, the powder can be quickly mixed evenly in the mixer
Horizontal Ribbon-spiral Mixing Machine
Horizontal Ribbon-spiral Mixing Machine is used to mix dry and powdery materials to achieve the purpose of mixing and mixing evenly. During mixing, the materials in the mixer are subjected to the movement of two rotors moving in opposite directions, and perform compound motion. The double-shaft paddles drive the materials to rotate clockwise and counterclockwise along the inner wall of the machine slot. The materials near the axis rotate axially, and the axial direction is pushed from the inside to both sides. The outer spiral drives the materials near the barrel wall to rotate axially, and the axial direction is pushed from both sides to the inside, thus causing convection circulation and shear infiltration mixing in the material barrel, completing the rapid and uniform mixing of the materials in a relatively short time.
Product features:
1. The U-shaped barrel structure is adopted, which has stable operation, uniform mixing, no dead angle, clean unloading, and a wide range of applications.
2. The inner and outer double-layer ribbons are used for staggered reciprocating mixing, with fast mixing speed and high uniformity
3. The bearings are at both ends of the mixer, and the materials are not easy to enter, and the maintenance rate is low.
4. The screw conveyor is easy to load, and the feed port is flush with the ground, which is labor-saving and convenient to feed.
5. The internal structure and overall design materials have passed the ISO9001 international quality system certification.
Working principle of Horizontal Ribbon-spiral Mixing Machine:
This machine consists of two parts: feeding and mixing.
1. Feeding part: Enter from the feed hopper, lift the material into the mixer through the spiral blade and enter the mixing drum for mixing.
2. Mixing part: When the material enters the mixing drum and performs back and forth staggered motion, the mixing effect is good.
Three-dimensional Mixing Machine
The working principle of the Three-dimensional Mixing Machine is different from that of the traditional rotary mixer. It performs unique translation, rotation, and rocking motion in the three-dimensional space of the cube, so that the material is in a complex motion state such as "rotational flow-translation-inverted falling body" in the mixing barrel, which is the so-called TURBULA state; it generates an alternating pulse to continuously push the material, and the turbulence generated by the motion has a changing energy gradient, so that each particle in the mixed material has an invariable motion state. Each particle constantly changes its position in the frequent motion diffusion, producing a satisfactory mixing effect.
Three-dimensional Mixing Machine consists of a base, a drive system, a three-dimensional motion mechanism, a mixing barrel and an electrical control system. The mixing barrel that is in direct contact with the material is made of high-quality stainless steel, and the inner wall of the barrel is precisely polished.
The series of three-dimensional swings is a novel material mixer widely used in pharmaceutical, chemical, food, light industry and other industries and scientific research units. The machine can evenly mix powdered or granular materials with good flow properties, so that the mixed materials can achieve the best effect.
1. Performance characteristics
1. With multi-directional movement, the material in the barrel has more mixing points and a significant mixing effect. Its mixing uniformity is higher than that of general mixers;
2. The inner wall of the mixing barrel of the three-dimensional swing mixer is precisely polished.
2. Precautions
1. The mixing of this machine is three-dimensional mixing. Safety guardrails are added within the effective range of the barrel to avoid life safety accidents. Before starting the machine, do not stand in front of the barrel to avoid accidents;
2. When loading and unloading, the electric power of the equipment must be stopped to prevent electrical failure and unnecessary accidents.
W series Mixing machine
Working principle:
The W series mixer is a double-conical rotary tank. In the vacuum state of the tank, steam or hot water is introduced into the jacket for heating. The heat contacts the wet material through the inner wall of the tank. The water vapor evaporated after the wet material absorbs heat is pumped away through the vacuum exhaust pipe by the vacuum pump. Since the tank is in a vacuum state, and the rotation inside the tank makes the material constantly flip up and down, inside and outside, the drying speed of the material is accelerated, the drying efficiency is improved, and the purpose of uniform drying is achieved.
Application:
This machine is used for vacuum drying and mixing of powder and granular materials in the pharmaceutical, food, chemical and other industries, especially for materials with the following requirements:
1. Thermossensitive materials that cannot accept high temperatures;
2. Materials that are easily oxidized and dangerous;
3. Materials that need to recover solvents and toxic gases;
4. Materials that require extremely low residual volatile content;
5. Materials that require crystal shape;
V-type Mixing Machine
Working principle:
The mixing barrel of the V-type mixer has a unique structure, high mixing efficiency, no dead angle, and is made of stainless steel. The inner and outer walls are polished, the appearance is beautiful, the mixing is uniform, and the use is extremely wide.
Application:
This machine is used for mixing dry materials and powder particles in pharmaceuticals, food, chemicals and other industries
