When we mention the shaker screen, we will definitely think of it as the main accessory of the slurry shaker, and it is also a wearing part of the shaker screen. In the daily operation of the shaker screen, the phenomenon of screen hole blocking will occur from time to time, so why will this phenomenon occur and what are the reasons for this phenomenon?

Screen plugging is one of the common faults in the operation of the vibrating screen, mainly caused by the following four factors:

1、Mesh and wire diameter matching

Practice has proved that the same mesh, too thick steel wire will cause a significant increase in the probability of plugging

2、The shape of stone

In the gravel production line, the content of needle flake stone should be as low as possible to prevent the phenomenon of screen plugging. Generally, the stone field adopts secondary crushing, a jaw crusher, its crushing principle is extrusion crushing, easy to produce flake stone, the secondary impact crusher, its crushing principle is impact crushing, if the size of the crushed stone is too small, it will produce more flake material, in order to reduce the ratio of needle flake stone, the second crushing size can not be too small.

3. Reasonable adjustment of screen tensioning force

Reasonable adjustment of screen tensioning force is an effective method to reduce screen plugging. Reasonable tensioning force causes slight secondary vibration between screen and support beam, thus effectively reducing the phenomenon of hole plugging.

4、The shape of the mesh

The screen generally uses square holes, and the small mesh uses the anti-blocking hole net. If the hole is really serious, the rectangular hole can also be used without affecting the particle size of the stone. However, considering the use cycle, it is necessary to pay attention to the direction of the mesh, otherwise it will affect the use cycle of the screen.

In addition, the screen is an important part of the vibrating screen, the correct selection and use of the screen directly determines the grade and quality of the product, so a good screen needs to meet what conditions. A good screen must meet the following conditions:

1. The material should be special wear-resistant steel wire, in the chemical composition of C and Mn requirements are high enough, while Si, P, S should be as low as possible. In the physical processing, the processing process requires to ensure that the material has the uniformity of fine organization as far as possible, the heat treatment requires to achieve the sortenitic organization, if conditions can be quickly heat treated to

2. The overall dimensions and the shape of the wrapping shall be correctly matched with the tensioning plate and screen frame on the screening machine

3. The form of weaving is reasonable, and the process must ensure that the steel wire weaving is tight and cannot be loosened

4. The wrapping form is reasonable, which is conducive to the tensioning of the screen

5. The screen is flat and parallel to each other

The above is the cause of the mud vibrating screen hole and some good screen needs to meet the conditions, hope to use the shaker screen and purchase screen customers help, if you want to inquiry the shale shaker and shaker screen, you can contact our company, our company is a manufacturer, we have focus on solids control industry about 20 years, our equipment price and quality are guaranteed.
