Which industrial fields and jet mills are the “best partners”?
The jet mill is mainly a crushing equipment that relies on particle collision for crushing operations. Its basic working principle is to accelerate the compressed air into a subsonic or supersonic airflow through the Laval nozzle, and the ejected jet drives the material to move at a high speed, so that the material collides, frictions and shears and crushes. These pulverized materials will be transferred to the classification area with the airflow for classification. The materials that meet the particle size requirements are collected by the collector, and the materials that do not meet the particle size requirements are returned to the crushing chamber to continue crushing until they reach the required particle size and are captured.
With the continuous advancement of technology. New jet mills are constantly being developed, making them easier to clean, simpler in structure and easier to install. At present, jet mills are widely used in many industries. It even plays an irreplaceable role in some production lines.
1. Pharmaceutical raw materials
It is indispensable to take medicine when you are sick. In order to allow the medicine to be fully absorbed by the human body system to exert its efficacy, the pharmaceutical industry generally has certain particle size requirements for most raw materials. Medical-related research shows that in solid pharmaceutical preparations, the particle size of the drug affects the rate of dissolution and release of the drug from the machine, which in turn affects the efficacy, bioavailability and availability of the drug. Especially for poorly soluble solid drugs, the smaller the particle size, the faster the dissolution rate and the more drug absorption.
2. Chinese medicine powder
There is no accompanying heat in the pulverization process of the jet mill, and the pulverization temperature is low, because it is also suitable for the pulverization of traditional Chinese medicine, especially heat-sensitive medicinal materials. The traditional pulverizer has certain limitations in the preservation of the active ingredients of traditional Chinese medicine, but the use of jet pulverizers can micronize Chinese medicinal materials, speed up the dissolution of active ingredients of traditional Chinese medicine, increase the dissolution rate, and increase the speed and degree of absorption.
3. Pesticide powder
Pesticide raw materials must go through a certain process to form a certain form of preparation before they can be used. If it is to be made into powder and granular form, then the indispensable step is the crushing of pesticide raw materials. If a jet mill is used, the powder particle size of the pesticide raw material can be crushed to 5-10 μm after ultra-fine crushing, and its uniformity, dispersibility, and drug contact area are significantly improved. Not only the bactericidal, insecticidal, and herbicidal effects are significantly enhanced, but also the amount of pesticides used can be greatly reduced.
4. Chemicals, oxides, non-metallic minerals and other new materials
Finally, there are countless chemicals, oxides, and non-metallic mineral products. The essence of the jet mill is a kind of equipment that crushes large particles into small particles, so as long as there is such a demand, the jet mill can be selected for production.
The configuration of the jet mill can be customized according to the needs of customers. Some parts can be made of ceramics (silicon oxide, zirconia, silicon carbide, etc.), high-hardness alloys, etc., to deal with various problems in the crushing process. For example, the airflow crushing equipment system dedicated to battery materials will be protected with ceramic patches, ceramic coatings, ceramic linings, etc. to avoid iron pollution during the crushing process and ensure the purity of the crushed materials. At present, in actual production, good results have been achieved in crushing silicon oxide, lithium iron phosphate, lithium carbonate and other materials.
The materials pulverized by air flow have the characteristics of ultrafine ultrapure, smooth particle surface, regular particle size, high activity, etc. Industries are pretty good choices.
