Dispersed irregular fracture of screen wire of 1. shale shaker
Under normal circumstances, the entire screen surface of the shale shaker screen is irregularly fractured. According to the grain condition of the fractured section, it can be determined whether there is a material quality problem. However, the stainless steel screen exceeds the material quality guarantee period. (some manufacturers of stainless steel in the warranty period of different length)
What are the reasons and solutions for the fracture of the shale shaker screen?
2. shale shaker screen presents linear fracture
The screen mesh of the shale shaker presents a linear fracture, which is generally due to the secondary vibration between the screen box support bar and the screen mesh formed under the state of the screen mesh not being tightened, and the linear and regular fracture of the screen mesh caused by mutual impact. Several possible causes of this damage are:
1. The size of the screen is too long, resulting in the tension screw is not tight;
2. There is a problem with the tensioning mechanism of the screen machine, the tensioning plate is not matched with the screen machine, and the tensioning plate is thinned or deformed;
3. The bending shape and size of the screen mesh are not matched with the tensioning plate;
4. Structural damage of screen body due to welding fracture of screen body;
5. The rubber cushion strip is worn or empty;
6. Defects in the design structure of the screen or sieve machine;
7. The support bar of the screen box is lower than the screen, that is, there is a certain distance between the support bar and the screen;
8. The stiffness of the four springs of the mud vibrating screen machine is uneven;
9. The amplitude of the mud vibrating screen machine is too large.
