Micro crushing technology is a newly emerging technology in the past decade, which greatly extends the concept of crushing on the basis of traditional crushing technology. In the Xinyou micro crushing machinery equipment, the application of air flow crushers and mechanical crushers in the pharmaceutical industry is currently more extensive. Among the air flow crushers, the fluidized bed air flow micro crushers are widely used, and the heavy pressure grinding type is also widely used in the mechanical crushers with good results.
When solid materials are finely ground in the pharmaceutical production process to a size of micrometers or even nanometers, the physical and chemical properties of the substance will undergo significant changes, thereby significantly improving the solubility of the drug and reducing its toxic side effects. Whether taken orally or externally, it can significantly improve the therapeutic effect. Especially in the field of traditional Chinese medicine, micro grinding technology can change the traditional methods of Chinese medicine. After being finely ground, Chinese medicinal materials can be directly used for oral administration, eliminating the tedious processes of decoction and decoction, greatly facilitating patients' medication.

Moreover, research has shown that the amount of refined traditional Chinese medicine used is only one tenth of the amount used in the original formula, greatly saving valuable resources of traditional Chinese medicine and effectively protecting the environment for its cultivation. In addition, through micro crushing technology, effective products that are difficult to dissolve or slightly soluble in water can be significantly improved in terms of drug bioavailability by cell wall breaking. This has opened up a new path for traditional Chinese medicine to go global. As a new technology, micro crushing technology has gradually been valued by relevant research departments and the pharmaceutical industry in China since the 1990s, and many theories of this technology are still in the stage of continuous exploration. With the continuous improvement and development of measurement technology and crushing theory, 'micro crushing technology and Jiangyin micro crusher' will be more widely applied in China's pharmaceutical industry.
When choosing to use a micro grinder, its operation must meet the following requirements:
1. Optimize the hierarchical structure. Grading is a crucial step in micro crushing systems, and a notable feature of micro crushers is their ability to achieve continuous feeding and discharging, preventing materials from being crushed too finely and causing unnecessary energy consumption. Appropriately increase the diameter of the grading wheel, increase the speed, and reduce the air flow rate to ensure that the separation particle size of the classifier is small.
2. Spiral feeder, oscillating feeder or star feeder can be used to ensure that the material supply in the crushing chamber can be obtained and meet the material concentration in the crushing chamber.
3. The dual frequency conversion control technology enables the machine to achieve a high level of control, greatly improving the discharge speed and fineness of materials.
4. The raw materials entering the micro crusher should be as small as possible. To achieve this goal, ordinary mechanical crushers should be used for pre crushing treatment before micro crushing, which is a direct and effective method to save energy and increase unit output.
