Jet mill is more suitable for crushing materials with high added value and good brittleness
The development of ultra-fine pulverization technology is becoming more and more rapid, thanks to the market demand for jet mill equipment. Jet mill, cyclone separator, dust collector, and induced draft fan constitute a complete pulverization system. The pulverization mechanism determines the scope of application of the pulverizer. The characteristics of wide and high fineness of the finished product. Typical applicable materials are: superhard diamond, silicon carbide, metal powder, etc.
The ultrafine pulverizer enters the cylindrical pulverizing chamber through the feed port, and the grinding wheel that moves in a circular motion along the grinding rail performs pulverization and shearing. The crushed materials are brought out of the crushing chamber by the negative pressure airflow generated by the fan and enter the material collection system. After filtering through the filter bag, the air is discharged, the materials and dust are collected, and the crushing is completed. By changing the ordinary air of the gas source into inert gas, such as nitrogen and carbon dioxide, the pulverizer can be used as an inert gas protection device. It broke the bottleneck of the crushing industry and brought the crushing industry to a new level.
The jet mill adopts supersonic jet grinding and cold plasma pulverization, which is completely different from the existing pure mechanical pulverization method. There is no local overheating in the crushing process, even if it is crushed at low temperature, it can be completed immediately, so as to maximize the retention of the biological activity of the powder components, thereby producing the required high-quality products. Due to the supersonic jet grinding, the feed force distribution is relatively uniform, avoiding excessive crushing, and the obtained ultrafine powder has a uniform particle size distribution, which greatly increases the powder’s adsorption, solubility, and specific surface area.
The ultra-fine powder jet mill adopts a closed system, which not only avoids polluting the surrounding environment, but also prevents the product from being polluted by dust in the air. It is widely used in the ultra-fine grinding of food and health products. In the crushing process, the microbial content and dust pollution are controlled, and products with ultra-narrow particle size distribution are produced. The collection rate of the conventional jet mill is more than doubled. The automatic control is realized, the operation is simple, the operation is stable, and the equipment is intelligent.
