The Chinese medicine pulverizer is a high-speed relative movement between the movable plate and the fixed plate, so that the pulverized material is pulverized by a combination of impact, shearing, friction and impact between the movable plate and the solid plate.
At present, the ultrafine pulverizer of Chinese medicinal materials has the following problems:
1. It is not easy to be stressed. Most of the Chinese herbal medicines are plants. They are various in nature and have different properties. A considerable part of them are rich in fiber and light in weight. They are not easily 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 herbal medicines have active ingredients, in the pulverization process, the temperature has a higher requirements, if blindly pursue the impact of high speed, often caused by excessive temperature, the medicinal materials are invalid.
3, the wall breaking effect 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 crushed to two or three hundred mesh, only some cells begin to break the wall, to achieve the effect For the purpose of breaking the wall, it should be appropriate to set the bottom line of fineness to about 500 mesh (equal diameter of 25 microns). Nowadays, the general ultrafine pulverizer is difficult to meet this requirement for Chinese medicinal materials.
4. High cost of use - When the current general ultrafine pulverizer is applied to Chinese medicinal materials, if a good pulverization effect is pursued, it needs to be repeatedly pulverized, and good production efficiency or cost cannot be achieved.
