Vibrating screen is an essential part of mobile crushing and screening equipment. It plays an important role in improving the output and quality of crushing and screening in the process of crushing and screening. The vibrating screen has the characteristics of simple structure, stable operation, high screening efficiency and large processing capacity. In the vibrating screen, the screen is the main working part to complete the screening process, and it is also the main wearing part.
After the screen is worn or damaged in long-term operation, it will confuse materials at all levels and seriously affect the quality of the finished product; incorrect operation and use will also cause the screen to break too quickly. Today, I will share with you the reasons and solutions for the excessive damage of the vibrating screen.
1.The quality of the screen material is not enough
After the screen is worn or damaged in long-term operation, it will confuse materials at all levels and seriously affect the quality of the finished product; incorrect operation and use will also cause the screen to break too quickly. Today, I will share with you the reasons and solutions for the excessive damage of the vibrating screen.
2.The screen plane is not tight enough
Solution: When installing or replacing the screen, 3-4 people should work at the same time, lay the screen on the screen frame, then put the screen compression ring, and use the screws to symmetrically work in accordance with the vertical direction of the screen. Fix, after the screen is unfolded and evenly tightened, thread the screws into the screw holes and slowly tighten them one by one.
3. Poor screen tensioning technology
Solution: Check the sieving progress of the screen frequently, check whether the screen is compacted, ensure the tension of the screen, reduce the pulsation power of the screen, and ensure that the sieve layer on the upper part of the screen and the force layer on the lower part are closely fitted.
4.The feeding amount is too large or uneven
Solution: When installing or replacing the screen, 3-4 people should work at the same time, lay the screen on the screen frame, then put the screen compression ring, and use the screws to symmetrically work in accordance with the vertical direction of the screen. Fix, after the screen is unfolded and evenly tightened, thread the screws into the screw holes and slowly tighten them one by one.
