The rapid development of traditional Chinese medicine superfine pulverizers is extremely important. It is extremely important for customers to correctly select the right ultrafine pulverizing equipment. Therefore, it is necessary to correctly understand the functions and applicable scope of various pulverizing equipment before selecting suitable products.
　　
Vibratory mill pulverizer, vibrating mill, ball mill and planetary mill are all similar pulverizing equipments, which can be used for ultrafine pulverization of traditional Chinese medicine. The working principle is that the Chinese herbal medicine to be pulverized and the grinding medium (such as metal balls, cylindrical rods, etc.) are placed together in a spring-supported grinding bucket, and the eccentric mass excitation device drives the grinding barrel to perform circumferential vibration, and the high-frequency vibration is passed through the grinding medium. The effects of impact, friction and shear on Chinese herbal medicines are achieved. The pulverization fineness can be adjusted and controlled by the grinding radius, the vibration angular velocity, the vibration time, or the ratio of the grinding media to the material. The vibration mill can also be combined with the freeze-grinding. The Chinese herbal medicine which is not resistant to high temperature is introduced into the cooling medium through the jacket, and the temperature is controlled within an ideal range.
　　
High-precision turbine grading and high-speed impact micro-powder:
　　
The combination of the two can successfully solve the temperature rise problem in the pulverization process by the expansion of the airflow, and can achieve the great energy-saving effect of the Zui, and has very good use reliability, and the pulverization particle size is less than 10 pm. The zui is up to 3-5pm, and the granularity is steplessly adjustable. Enterprises and research institutes mostly pay attention to the crushing effect of equipment, but whether the equipment meets GMP requirements and how to achieve cleaning, disinfection and automation control needs further research.
　　
Jet mill and grading:
　　
The jet pulverization is carried out by impacting the pulverized material by a high-speed air stream to achieve the pulverization purpose. In a general airflow pulverizing equipment, a gas flow having a static pressure of 0.8 to MPa is converted into a high-speed fluid of 2 to 3 times supersonic kinetic energy through a special nozzle, and the kinetic energy of the high-speed gas impacts the pulverized material to cause an impact. The pulverized materials collide with each other to pulverize the material. This type of equipment has a fast processing speed and a large processing capacity, but it has a large investment, takes up a large space, and is very noisy, and is not suitable for small and medium-sized enterprises.
　　
New heavy-pressure grinding superfine pulverizer :
　　
Equipment for superfine grinding of dry materials by means of heavy pressure grinding and shearing. It consists of a cylindrical crushing chamber, a grinding wheel, a grinding rail, a fan, a material collection system, and the like. The material enters the cylindrical crushing chamber through the feeding port, and is crushed and sheared by the grinding wheel which is circularly moved along the grinding rail to realize crushing. The pulverized material is taken out of the pulverization chamber by the negative pressure airflow caused by the fan, enters the material collection system, is filtered through the filter bag, the air is discharged, and the materials and dust are collected to complete the pulverization. Such pulverizers have been widely used in medicine, chemicals, food, and universities, and have achieved good economic and social benefits.
