Dry pulverization method, also known as conventional pulverization, refers to pulverizing the drug after proper drying treatment. Such as iron grain, ball mill, hammer, universal crusher, etc., the method has the advantages of simple operation, once powder, but it is that continuous operation is easy to generate heat and ignition. In practice, depending on the pharmaceutical land, it can be divided into the following four methods.
(1) Separately pulverized a drug alone. This method is suitable for the smash of resins, gums, precious, poison, small drugs. (2) Hybrid pulverization means that all or part of the component in the formulation is mixed together to pulverize. The ultrafine pulverizer is a super-small grinding ultra-fine pulverizer, suitable for university laboratories, factory laboratories, pharmacies, Chinese medicine hospitals, and families to do fine grinding. Hongxu series models can be widely used in the ultrafine pulverization needs of Chinese medicine, western medicine, pesticide, biological, cosmetics, food, feed, chemical, ceramics, metallurgical minerals. Especially for fiber (such as Chinese herbal medicine, ganoderma lucidum, etc.), high hardness (such as diamond, ceramics, etc.), the crushing effect of high hardness (such as diamond, ceramics, etc.) is more perfect. The present invention is applicable to group medicines similar to the mass in mass. This method avoids the difficulty of the pulverization process due to the viscosity or oilyness of certain drugs. Such as cooked, Angelica, Apricot Thai and other drugs are pulverized. (3) Converse method is also known as string oil, which is to leave a small "oily" powder, and then pulverize other drugs into powder, and then add a mixed powder to Taiwan's "oily", and then pulver once. (3) Converse method is also known as a string oil method, that is, the "oily" small powder is left behind, and other drugs are pressed into powder. Thus, the first batch of pulverized drugs can be absorbed in time, not sticky to the crusher and the screen. Add Ma Ren, Almond, Melon, Said, etc. (4) String powder, also known as a string, that is, "viscous" large material left in the prescription, first mix other components into a coarse powder, and then mix it with "viscous% powder", and then Smash. (4) The fine rope grinding method is also known as the fine rope, that is, the "viscous" in the prescription is reopened, and other components are mixed into coarse powder, and then pulverized. Its viscous substance is being crushed. It is dispersed and adsorbed by light pulverized powder. In this way, smashing and screening *, such as ginseng, party ginseng, longan meat, etc. When crushing and grinding, the instrument or aggregate is bonded to the instrument or the aggregate when the wet is broken.Fragments (such as ice sheet). If the drug is pulverized with an appropriate amount of water or other liquid, it is easier to form fine powder.
