The jet mill runs without heating, pollution, and easy to clean
Jet mill is a commonly used grinding processing equipment, which can be used for dry grinding treatment of various materials with Mohs hardness 1-10, especially for some materials suitable for high hardness, high purity and high added value. The particle size of the product can be controlled between D97: 2-150 microns and can be adjusted very well. The particle shape is also very good, and the…
How to improve the grinding efficiency of jet mill
In recent years, with the development of modern industry, ultra-fine and ultra-fine pulverization technology has received more and more attention, especially the quality of the pulverization effect of raw materials in the pharmaceutical and chemical industries directly affects the subsequent process. The jet mill is the best in the current ultrafine and ultrafine grinding equipment, especially…
What are the factors that affect the grinding efficiency of jet mills?
Jet mill is a kind of equipment that uses high-speed air flow energy (300~500m/s) or superheated steam (300~400℃) to make powders collide, collide, and rub against each other to make them grind. The nozzle sprays high-pressure air or high-pressure hot air, and then rapidly expands to form a high-speed airflow. Due to the large velocity gradient near the nozzle, most of the grinding occurs near…
How to solve the problem of excessive dust when the jet mill is working
The jet mill, cyclone separator, dust collector, and induced draft fan constitute a complete pulverization system. After the compressed air is filtered and dried, it is sprayed into the crushing chamber at high speed through the Laval nozzle. At the intersection of multiple high-pressure airflows, the materials are repeatedly collided, rubbed, and sheared to be crushed. The crushed materials rise…
How to deal with the blockage of jet mill
There are many grinders in our daily life, such as small grinders, Chinese medicine grinders, jet grinders, and so on. But in the process of use, sometimes there will be some failures, sometimes the grinder is blocked, when it is blocked, how should we deal with it? In fact, clogging is a very common failure of the grinder during grinding, and the main reason is still caused by the operation.…
What are the irreplaceable functions of the jet mill
Jet mills are widely used in chemical, mineral, metallurgy, abrasives, ceramics, refractory materials, medicine, pesticides, food, health products, new materials and other industries. The reason why it is chosen as the factory production equipment is that the jet mill does have an irreplaceable role.
The working principle of the jet mill: Qualified fine powder is brought into the turbo…
Three major processes of jet mill that must be mastered
As an important pulverizer, the operation process of the jet mill must be mastered first. Only when you understand the safe operation rules can you perform correct operation.
Preparation before starting
(1) After receiving the production instruction, prepare the materials in advance.
(2) Inspect the pipes, fastening bolts, gaskets, spindle bearings and instrument panels to see if…
How to use and maintain the jet mill
The application of jet mill is very wide, and some matters need to be paid attention to when using, including preparation work and operation process before starting up, maintenance work and so on.
Preparation before starting
Check whether the host, connecting machine, pipes and valves are in good condition and can work normally.
Turn on
Boot sequence:
Ensure that the…
Classification and working principle of jet mill
Jet mill, as one of the ultrafine grinding equipment, is also one of the important equipment in the grinding industry. After the compressed air of the fluidized bed pulverizer is frozen, filtered and dried, it forms a supersonic airflow through the nozzles and is injected into the pulverizing chamber to fluidize the material. The accelerated material merges at the intersection of the jet airflows…
Application status and prospect of jet mill
Jet mill, also known as jet mill, refers to the equipment that uses the energy of high-speed airflow (300～500m/s) or superheated steam (300～400℃) to make particles collide, collide and rub each other to achieve ultrafine grinding. Compared with other types of shredders, it has the following advantages:
① Good product granularity. The average particle size (d50) of the material is generally…
