What is the reason why the screen mesh of the vibrating screen is damaged too quickly

Hello, the reason for the blockage of the linear vibrating screen is most likely because the particle size of the material is almost the same as the particle size of the screen mesh.

The screen is not taut – replace the adjustment screen.

Uneven blanking - change the blanking method or install a distributor Instantaneous blanking is more - change the blanking method or install a distributor There are foreign substances in the material - pay attention to the control of the previous process.

There are many reasons, first of all, it is easy to break or damage where is the position, whether it is the feed end, or the middle, and then whether a screen is.

Tension. It is recommended to use what kind of screen according to the particle size and characteristics of the material, if you have to use the screen, you can consider installing a lining to increase its life!

There are five main reasons for the plugging of the screen:

1) Contains a large number of critical material particles close to the separation point. That is, the particle size of the broken stone is critical with the mesh size of the screen, and the stone is stuck in the mesh during the screening process, and this kind of particle is stuck in the mesh and cannot pass through the screen smoothly to cause the hole blocking, which is called the critical hole plugging.

2) There are many materials with the shape of multiple contact points for the sieve hole.

The vibrating screen needs to be inclined, and the vibrating stones will be separated when working.

When the vibrating screen is working, the sieve has an inclination, so it will not be blocked.

There are many factors that affect the screening rate of materials, but there are two main categories to sum up, one is the various characteristics of the material itself, and the other is the structure of the vibrating screen. After analysis, it was found that the reason for the blockage of the vibrating screen mesh was mainly due to the fact that there were many fine-grained materials in the screened materials, and the size of these fine-grained particles was relatively close to the size of the sieve hole, which was easy to get stuck on the sieve hole and cause blockage; In addition, the screening material is also relatively wet, and the moist fine particles will bond into a clump and adhere to the screen surface, making the screening process difficult to complete. It is difficult to change the nature of the material, so the solution to the blockage problem should mainly start from the structural form and screen structure of the vibrating screen.

Second, the main methods to solve the blockage problem focus on two aspects: the structural form and vibration intensity of the vibrating screen and the structural form of the screen. From the perspective of the development of the structure of the vibrating screen, there are various forms of vibrating screens such as probability screens, relaxation screens, and constant thickness screens, which have made some progress in solving the problem of blockage, but the screens can not be effectively self-cleaned, and are generally only used for material classification above 13 mm.

Since the material is layered and screened on the screen surface, the larger the effective screening area, the larger the screen volume per unit time of the screen surface, and the higher the production efficiency. Therefore, increasing the screen surface area under the condition of a certain processing capacity can reduce the thickness of the material layer, which can improve the screening efficiency to a certain extent, but at the same time, it will also make the vibrating screen too cumbersome, and increase the equipment and civil engineering costs. The vibration intensity is too small, which will cause the material to not be fully loose and affect the screen, and increasing the vibration intensity can improve the screening efficiency, but if it is a sticky wet fine-grained material, the material will be tightly glued to the screen, the overall movement of the material layer, the difficulty of layering, the improvement of the vibration intensity is not obvious to the solution to the blockage problem, and the vibration intensity is too large will damage the side plate, pipe beam, exciter, etc. of the linear vibrating screen, and reduce the service life of the vibrating screen.

The service life of the screen is determined by a variety of factors. First of all, check the on-site operation: the feeding speed is fast, the feeding position is relatively large, the feeding position is higher from the inlet, and the medium and sharp foreign matter enters the sieve machine.

On the other hand, start from the sieve machine: the form of the grid is not properly selected, the screen is too tight or too loose, the screen quality is poor, and the seal is selected or equipped with the wrong one. Specifically, the vibrating screen manufacturer can assist in inquiring and solving.

Summary. What should I do if the screen is broken? Hello dear!

First of all, the screen itself is a wearing part, and the reason for the rapid damage of the vibrating screen screen is analyzed: 1. The screen surface of the installed vibrating screen screen is as smooth as a sheepskin drum, and there can be no tight and loose situation, otherwise the damage will be fast. If the tensile force is too tight, the aperture of the screen is easy to deform, and the tensile force is too loose, which affects the screening efficiency, which requires the use of a tension tester to detect; 2. Another reason for the rapid damage of the screen is related to the nature of the material itself.

For example, if you use a 100-mesh screen to screen iron powder and starch, the service life of the screen will be different, I hope it can help you!

1. The screen surface of the installed vibrating screen screen is as smooth as a sheepskin drum, and there can be no tight or loose situation, otherwise it will be damaged quickly. If the tensile force is too tight, the aperture of the screen is easy to deform, and the tensile force is too loose, which affects the screening efficiency, which needs to be detected by a tension round rock tester; 2. Another reason for the rapid damage of the screen is related to the nature of the material itself. For example:

The same use of Brother Nian 100 mesh screen to screen iron powder and starch, the service life of the screen is not the same, I hope to help you!

Hello, dear, thank you for your patience, the answer has been found for you, you check it, thank you!

What should I do when the screen has been used very well, but suddenly the following problems appear?

Rotary vibrating screen. Gaofu recommends that you maintain the screen daily, as follows;

1.Do not place heavy objects on the screen surface, and handle them gently when disassembling and assembling, so as to avoid damage caused by sharp objects touching dates;

2.When there is a blockage of the net, it can be cleaned with a soft brush, or it can be washed with air blowing and water, so as not to damage the aperture and wire diameter of the screen;

How to find the damage of the rotary vibrating screen screen, the details are as follows;

1.Check once per shift to see if there is any damage;

Stop this stool 2The particle size of the screened finished product can also be detected regularly during the screening process;

3.According to the result after the inspection, judge whether the screen has the condition of damage;

Maintenance after the screen of the rotary vibrating screen is damaged, as follows;

Jane Brigade 1If your company is equipped with a sub-parent grid on site, the screen can be changed immediately after the screen is damaged;

2.It can be equipped with the same specification and the same number of screens used by the screen machine in advance;

When screening materials, adjust the amount of feeding, it is best to feed the material evenly, to prevent the material from staying on the net for too long, if the material stays too much, it will make the screen tension damage and cause the problem of pocketing phenomenon.
