Advantages of jet mill
The structure of the jet mill: It is mainly composed of a grinding chamber, a nozzle orifice, a material outlet, an air flow outlet, a compressed air inlet, and a classification zone. The flat jet mill has a wide range of applications due to its simple structure and easy manufacturing.
Working principle: The compressed air or superheated steam is transformed into high-speed air flow through the nozzle. When the material is fed into the crushing chamber through the feeder, it is sheared by the high-speed air flow. The strong impact and intense friction make the material grind into ultra-fine products. The power engine and grinder are smooth and not prominent. Do not change the pulley at will, lest the speed is too high to cause the grinding chamber to burst, or the speed is too low, which will not affect the working efficiency of the grinder. The jet mill should be idling for 2-3 minutes after starting, and there should be no abnormal phenomena before the feeding operation. Pay attention to the working status of the grinder during the operation, feed evenly, prevent clogging, and do not overload the operation for a long time. If there is vibration, noise, bearing and body temperature too high, the appearance of spraying should be stopped immediately, and the operation should be continued after troubleshooting. With the development of society, some devices have made great breakthroughs in order to play a better role. The jet mill has a good effect on the grinding target and occupies a special position. In the process of operation, the use of the jet mill should pay attention to certain operations, which cannot meet the production needs and work overload. Therefore, we should pay attention to the maintenance of the jet mill to ensure its efficiency.
Advantages of jet mill
1. Non-heating, especially suitable for ultra-fine grinding of heat-sensitive materials. In addition, air can be replaced with inert gas, which is suitable for grinding inflammable and explosive materials.
2. The pollution is very small. Since the grinding principle is the collision grinding of the material itself, compared with other grinding forms, the method of blade or ball grinding will be introduced into other grinding media for comparison. The jet mill is a pulverizing process with minimal pollution, especially suitable for industries such as medicine and food.
3. It is easy to clean, and the internal transmission of airflow grinding is smaller than other ultrafine grinding machines. In particular, the spiral airflow grinder is simple in structure, easy to clean, has no dead ends, and can be used as a sterile medicine grinder.
