Fine powder generally refers to fine powder materials with a higher mesh number. This type of material has the characteristics of high screening mesh, easy to overflow, light specific gravity, and easy to block the network. The fine powder screening machine is an important type of vibrating screen. It can be used to screen a variety of powder materials with a high degree of precision. It is a universal screening equipment for many companies. During the use of the fine powder sieving machine, various problems are often encountered, which confuses users.

1. Pay attention to dust spillage
Because some of the fine powder has a lighter specific gravity, there will be a problem of dust emission during production

2. screen mesh broken
The production of fine powder usually requires high precision, and the screen is a component that carries the material. During the long-term operation of the equipment, the problem of slack and breakage of the screen due to the heavy blow and tension of the material will occur. Once the screen is loose or damaged, it will cause insufficient screening accuracy and affect the product effect. So it is necessary to replace the screen or tension screen in time.

3. Wear of the rubber strip
In the fine powder sieving machine, there are generally two types of rubber strips, U-shaped and V-shaped. Among them, the U-shape is used to protect the grid, seal and prevent powder leakage, while the V-shape is for sealing and damping. Therefore, when the rubber strip is worn or too loose, powder leakage will occur. Users should pay attention to the abrasion of the rubber strips when using the fine powder screening machine. You can prepare a few more to avoid damage to the screening machine.

4. Pay attention to the installation of ring and fasteners
In the maintenance process of the sieve machine, pay attention to the tightening of the ring bolts not to be too loose or too tight. Too loose will lead to insufficient compression of the grid frame, and material leakage during the operation of the sifter, even the screen frame Dropping or over-tightening will result in failure of the sliding wire of the ring bolt or directly destroy the ductility of the rubber skin. So in the process of using, always check the condition of the fasteners and keep them in good working condition.
