Abstract
For Chinese herbal medicine (CHM), tea, coal and other materials, the finer the grinding particles, the better the reaction and adsorption capacity, and the higher the utilization rate. The use of CHM achieving ultra-fine powder can improve the bioavailability of the active ingredients of the drug, speed up the absorption of the human body. In the same time, coal grinding to the micron level can also increases the rate of combustion reaction. Based on the theory of ball mill, a new ultra-fine grinding machine technology method was proposed, and the experimental grinding of materials was carried out. The results showed: by grinding data of a single medicinal material, it can generally grind in 15 minutes to a state of less than 5 um in 95%; for mixed medicinal materials, if the conditions of rough processing and different durations were used, the processing effect has been found to be more efficient, and the fineness of the particles in the case of D50 is 12.290 um.
