Ultrafine pulverization technology is an important part of powder engineering, including ultrafine pulverization of powder raw materials, high-precision grading and surface activity change. According to the size or particle size of the raw materials and finished particles, the pulverization can be divided into coarse pulverization, fine pulverization, fine pulverization and ultrafine pulverization, which is a rough classification. It is worth noting that the size of the ultrafine powders is differently divided in various industries in various countries due to the use of ultrafine powders, the difference in preparation methods and technical levels.
The ultrafine pulverizer is generally a sieveless pulverizer. The particle size of the pulverized material is controlled by the gas flow rate. The pulverization particle size is required to pass 95% through 0.15mm (100 mesh). It is generally used for special aquatic bait or aquatic open bait. Ultrafine pulverization is usually super The micro-grinder , pneumatic conveying and classifier are matched to complete. The pulverized particle size of the raw material is very fine, which may show unexpected characteristics, but it also brings more problems, such as electrostatic adsorption, poor fluidity of the material, large energy consumed by pulverization, increased production cost, and influence on processing operations. Larger, these adverse effects can be overcome in different ways (such as changing the feed processing process).
The ultrafine pulverizer is an outward-oriented type high-speed pulverization. The material enters the pulverization chamber and is crushed by a rotating hammer to obtain the smashing effect of the ambition. The pulverized material is actively entered into the collecting bag, and the dust is recovered by the dust box through the bag. There is no dust flying during the production process, and it can improve the utilization rate of materials and reduce the company's cost. The whole machine is made of stainless steel material, which conforms to the "GMP" standard. The crushing chamber is easy to assemble and disassemble and clean. It is a new generation of vacuuming and crushing equipment for pharmaceutical, chemical and food industries.
In recent years, the newly developed Chinese medicine pulverizer and ultra-fine extraction and wall-breaking technology have brought new opportunities for the development of traditional Chinese medicine. When the Chinese medicine is ultra-fine pulverized, the Chinese medicine is crushed to the level of broken wall by the ultra-fine pulverizer , which further improves the level. The absorption effect of the Chinese herbal medicine on the human body has also improved the taste of the Chinese herbal medicine. The value of the Chinese herbal medicine after the ultra-fine extraction is several times or even tens of times higher than the raw material value of the Chinese herbal medicine. Due to the relatively low price of the small ultrafine pulverizer , the land is occupied. Small, easy to use and easy to operate, so that the majority of Chinese herbalists and Chinese herbal medicine research and development units are favored
