How does the jet mill control the particle size?

How does the jet mill control the particle size? The smaller the particle size of the raw material, the higher the crushing efficiency. On the contrary, the larger the particle size of the raw material, the lower the crushing effect. When the crushing pressure and the feed pressure are constant, the product will be finer when the feed rate is reduced, and the product will become coarser when the feed rate is increased. In the case of a certain feed rate, the particle size of the product will be finer when the crushing pressure is increased, and the product will become coarser when the crushing pressure is reduced. Therefore, the particle size control is achieved by adjusting the parameters of the jet mill during the crushing process to achieve different crushing fineness. Before crushing, the relationship between the feed rate and the pressure needs to be measured and then the appropriate crushing parameters are determined to meet the customer's particle size requirements. .

 

The particle size of the end product needs to be checked with a particle size detector to check the fineness and distribution range. In addition, if the electron microscope is used for measurement, it can be more accurate. Of course, the detection result can also be compared with the particle size detector.

 

How does the jet mill adjust the particle size of the finished product?

 

Generally, the particle size of the jet mill can be adjusted by the change in the feed rate. When the rate is reduced, finer particles can be produced. Since each particle has more energy to accelerate the impact and crushing, it provides a greater power supply, which becomes the impact of crushing. The important force of, you can also get more fine grain size, it is under the premise of energy consumption.

 

Some products need high-level application of crushing energy to crush. Jet mills can improve crushing characteristics, increase pressure, temperature, gas flow control, etc. Increasing temperature will also change the material, all control particle size, but also need to consider the physics and chemistry of the material characteristic.

 

Adjust the output power of the diameter grinder properly. Some particles must be processed when they have a low resonance, which requires multiple collisions. Therefore, when the resonance is increased, the particle speed is given a lower energy for each collision. On the other hand, to reduce the number of particles, the speed of the particles must be increased.

 

In addition, pay attention to the use of the equipment, read the instructions carefully before operating, and understand the characteristics and structure of the equipment. It is not possible to increase the speed of the spindle, and there should be no lumps in the material, which will cause damage to the equipment. When loading the material, it should be on the side of the material opening to prevent the material from flying out.

 

The bearing temperature must be below 55 degrees, and the equipment must be stopped for inspection if it is too hot. Clean up the materials in the collection bag. When replacing the hammer, open the casing to clean up the blockage and cut off the power supply. At the end of the work, the equipment must be cleaned and protected from fire. People who don't know the equipment or people who are drunk or sick are not allowed to operate it.

 

Do not use inferior hammers, which will affect the service time of the equipment. If there is a fault, please check again after power off. The equipment must have a protective cover when it is working, and the equipment must be checked before starting the machine.
