1. The quality of the screen is not good and the material is not qualified, so the screen is often damaged in use.

2. The abrasion resistance of the screen is not enough, and the material of the screen cannot meet the requirements of material screening.

3. If the tension of the screen is not enough, too tight or too loose, the material will damage the screen during the movement.

4. Too much material is put into the screen, which leads to heavy load-bearing and overworked screen, thus affecting the service life of the screen.

5. The vibration amplitude is too small, which causes the materials to accumulate on the drying net for a long time. We can adjust the vibration amplitude to increase the movement of the materials on the screen and reduce the load of the screen.
