What are the advantages of using jet mills?

As the powerful advantages of jet mills overcome the shortcomings of traditional grinding machines, jet mills are used more and more widely. What are the advantages of jet mills? Let’s take a look together.

1.    The grinding particle size is small and the distribution is even. Because the force distribution on the jet mill material is quite uniform. Ultra-fine grinder is a device that uses air separation, high-pressure grinding, shearing and other technologies to achieve ultra-fine grinding of dry materials. It is composed of cylindrical crushing chamber, grinding wheel, grinding rail, fan, material collection system, etc. The setting of the classification system not only strictly restricts large particles, but also avoids the occurrence of over-grinding, thereby obtaining ultra-fine powder with uniform particle size distribution. At the same time, the specific surface area of ​​the micropowder is greatly increased, and the adsorption capacity and solubility also increase correspondingly. Save raw materials and improve utilization: After ultra-fine grinding, the ultra-nano-level ultra-fine powder can be directly used for preparation production, while conventional grinding products still need some intermediate links to meet the requirements of direct use and production, which may cause waste of raw materials . Therefore, this process is particularly suitable for the grinding of rare raw materials.

2.   Reduce pollution and be more environmentally friendly: Ultra-fine grinding is carried out in a closed system, which not only avoids the pollution of the surrounding environment by micro-powder, but also prevents the product from being polluted by dust in the air. Therefore, the jet mill is applied to food and health products to effectively control the specific gravity of microorganisms and dust. The ultra-fine grinder has a high speed and can be pulverized at low temperatures. Ultra-fine grinding technology uses supersonic jet pulverization, cold grinding and other methods, which is completely different from the previous pure mechanical pulverization methods. The crushed materials move to the classification area with the updraft under the action of the fan suction. Under the strong centrifugal force generated by the high-speed rotating classification turbine, the coarse and fine materials are separated, and the fine particles that meet the particle size requirements enter the cyclone separator and dust removal through the classification wheel. The coarse particles are dropped to the crushing area and continue to be crushed.

3.   During the grinding process, there will be no local overheating phenomenon, and it can even be pulverized at low temperature. The speed is fast and can be completed in an instant. Therefore, the biologically active ingredients in the powder can be retained to the maximum, thereby producing the required high-quality products.
