Ultrafine crusher type and function analysis

1. mill vibration mill, a vibration mill, a ball mill and a planetary mill or the like belonging to the same grinding apparatus can be used in medicine ultrafine grinding. The working principle is to put the Chinese herbal medicine to be smashed into a spring-supported grinding barrel together with grinding media ( such as metal balls, cylindrical rods, etc. ) , and the eccentric vibration is driven by the eccentric block to drive the barrel to make a circular vibration, and the high-frequency vibration is induced by grinding. The effects of impact, friction, and shear of Chinese herbal medicines are achieved by smashing. Slurry fineness can be adjusted and controlled by the grinding media radius, the vibration angular velocity, the vibration time or the ratio of grinding media to the material. Vibration mill can also be combined with freezing and smashing . It is a kind of current application that the Chinese medicinal materials that are not resistant to high temperature are introduced into the cooling medium through the jacket and the temperature is controlled within the ideal range.

2.High- precision turbine grading and high-speed impact powder machine: The combination of the two can successfully solve the problem of temperature rise in the crushing process through the expansion of the air flow, and can achieve large energy-saving effects, and has a very good use of reliability. Crushing particle size up to 10pm . The fineness can reach 3-5pm and the granularity can be adjusted steplessly. Most enterprises and research institutes pay attention to the crushing effect of equipment. However, whether the equipment meets the high standards and how to achieve cleaning, disinfection, and automatic control require further research.

3. Air-flow crusher and classification: The air-flow crushing achieves the purpose of crushing by impacting the material to be crushed by the high-speed airflow. In a general air flow smashing device, it has 0 . The airflow from 8 to MPa static pressure energy passes through a special nozzle and turns into a high-speed fluid with a kinetic energy of 2 to 3 times the supersonic speed. The kinetic energy of high-speed gas impacts the crushed material, causing the crushed materials to collide with each other and crushing the material. This type of equipment has a high processing speed and a large amount of processing, but it has a large investment, occupying a large space, and has a lot of noise. It is not suitable for small and medium enterprises.

4. New type heavy pressure grinding type ultrafine pulverizer: It uses the form of heavy pressure grinding and shearing to realize the ultrafine pulverization of dry materials. It consists of cylindrical crushing chamber, grinding wheel, grinding track, fan, material collection system and other components. The material enters the cylindrical crushing chamber through the feeding port, and is ground and sheared by the grinding wheel that performs circular motion along the grinding track to achieve crushing. The crushed material is taken out of the crushing chamber by the negative pressure air flow caused by the fan, enters the material collection system, is filtered by the filter bag, the air is discharged, and the materials and dust are collected to complete crushing. Such crushers have now been widely used in medicine, chemical industry, food, and universities, and have achieved remarkable economic and social benefits.
