Powder mechanical stirring mixing is a mixing process widely used in industries such as pharmaceuticals, chemicals, and food. Its basic principle is to mix different powder materials evenly through mechanical stirring, thereby achieving certain physical and chemical properties. The common mechanical stirring and mixing methods for powder are as follows:
1. Drum mixing method: Using the continuous rotation and rolling of the drum, the powder is continuously stirred and mixed with each other. The drum mixing method is suitable for mixing a certain proportion of powder, and has no requirements for the shape and size of the powder. The mixing effect is good, and the process is simple.
2. Shaker mixing method: Using the vibration of the shaker to mix different powders together, this method is suitable for mixing powders with different proportions and shapes and sizes. The shaking table mixing method has a short mixing time, high efficiency, and minimal wear on the powder.
3. High shear mixing method: This method uses the high-speed rotation and high shear force of the stirrer to mix powder, suitable for powder mixing with uniform particle size and the same proportion. The high shear mixing method has good mixing effect, but it requires high requirements for agitators and equipment.
4. Extrusion mixing method: This method first mixes different powders in advance, then extrudes the mixture into flakes or fine filaments through an extruder, and finally achieves the powder mixing effect through cutting and coiling. The extrusion mixing method is suitable for mixing with different mixing ratios and high requirements for the shape and size of the powder.
In summary, there are various methods for mechanical mixing of powders, and different mixing methods are suitable for mixing powders with different properties, resulting in better performance of mechanical mixing. At the same time, the application of these hybrid methods has greatly promoted the development of various industries, providing strong support for people's lives and health security.
