The ultra-fine pulverizer is through the high-speed relative movement between the movable disk and the fixed disk, so that the pulverized material can be crushed through the comprehensive action of the impact, shear, friction between the movable disk and the fixed disk, and the collision between the materials. .

At present, the ultrafine pulverizer of Chinese medicinal materials has the following problems:
1. It is not easy to bear force - most of the Chinese medicinal materials are plants, which are of various types and have different properties. A considerable part is rich in fiber and has a light specific gravity. It is not easy to be affected by mechanical force in the crushing machine. Users often have The feeling of "hammer hitting cotton".

2. The temperature is too high - most of the Chinese medicinal materials have active ingredients. During the crushing process, there is a high requirement for the temperature. If the impact force brought by the high speed is blindly pursued, the temperature will be too high and the medicinal materials will fail.

3. The effect of breaking the wall is not good-the cell diameter of Chinese herbal medicines is generally between 10 and 50 microns, and some of them reach 70 microns, so when they are crushed to two or three hundred meshes, only some cells begin to break the wall, which must be achieved to improve the efficacy of the medicine For the purpose of breaking the wall, it is more appropriate to set the bottom line of fineness to about 500 mesh (the equivalent diameter is 25 microns). However, the current general ultrafine pulverizers are difficult to meet this requirement for Chinese herbal medicines.

4. High cost of use - when the current general superfine pulverizer is applied to Chinese herbal medicines, if a better pulverization effect is pursued, it needs to be pulverized repeatedly, which cannot achieve good production efficiency or cost.
