Working principle of traditional Chinese medicine ultrafine grinder

The traditional Chinese medicine ultrafine pulverizer adopts the working principle of vibration pulverization. A certain amount of grinding medium, such as hard material balls, rods or columns, is filled in the grinding cylinder (pulverization chamber). Under the action of external excitation force, the grinding cylinder produces circular vibration in the clockwise and counterclockwise directions as shown in Figure 1. The strong vibration of the grinding cylinder causes the medium inside the grinding cylinder to undergo a throwing motion. Under the action of this throwing motion, each medium produces a rotational motion in the same direction as the circular vibration. At the same time, the medium group also produces a low-frequency orbital motion of 3-5 cycles opposite to the circular vibration. So the medium sometimes disperses and sometimes collides with each other, producing a positive impact force p and a lateral shear force L. The material is finely ground, broken, and crushed under the impact, compression, and shear forces of P and L.

The traditional Chinese medicine ultrafine grinder adopts multiple excellent technologies and applies high-speed impact force and shear force according to the different characteristics of the materials, so that the materials are subjected to high acceleration impact, friction, compression, cutting and other effects of the medium in the grinding cylinder, and can achieve ideal crushing effect in a very short time. The material becomes fluidized during the crushing process, so that each particle has the same stress state, achieving precise mixing (dispersion) effect while crushing. By adjusting parameters such as acceleration, it is possible to achieve operations with the goal of crushing and grinding or precision mixing (blending) as the main objective.

The traditional Chinese medicine ultrafine grinder adopts the following excellent technologies:

1. Fully enclosed non graded technology: The fully enclosed multi grinding non screening technology used to preserve the active ingredients effectively avoids phenomena such as segregation and loss of active ingredients, and environmental pollution caused by dust spillage.

2. Compression micro crushing technology: In order to improve the crushing efficiency and effectiveness, high-speed impact force and shear force are used to subject the material to the squeezing, kneading, and tearing effects of the medium in the grinding cylinder, greatly shortening the crushing time and improving the crushing efficiency; At the same time, due to the fluidized state of the material and the same stress state of each particle, its own viscous effect can form uniformly dispersed and precisely composite particle clusters in the finished product, increase density and improve bioavailability, and enhance micro crushing efficiency and technology.

3. Dynamic optimization technology: a technology that optimizes and adapts according to the different characteristics of materials while ensuring the improvement of micro crushing efficiency and effectiveness.

4. Mechatronics technology: a technology that achieves high performance and level of equipment, reduces manual labor, ensures stable and controllable product quality, and avoids quality instability and pollution caused by excessive manual intervention.

5. Comprehensive automation technology: equipped with single machine multifunctional automation (FMC flexibility), making small-scale drug production as simple as large-scale assembly line production.

6. Clean and safe technology: The traditional Chinese medicine ultrafine grinder is designed and manufactured strictly according to GMP standards, which can meet the special requirements of pharmaceutical powder equipment.
