1. Check whether the screen mesh and the discharge port are level or too high. Generally, they should be about 5mm higher, and the height of the discharge port should be designed differently according to the characteristics of different materials.

　　2. When the linear vibrating screen or ultrasonic vibrating screen is working, check whether the screen surface or discharge port is in a horizontal state, which directly affects the screening effect of the equipment; If it is not horizontal, it should be adjusted in a timely manner. The vibrating screen is equipped with supporting feet, and customers can adjust the feet to make the vibrating screen meet the horizontal requirements and lower it appropriately.

　　3. In addition to the above situations, the key point is that the angle of the upper and lower eccentric blocks of the vibration motor can be adjusted. A smaller angle allows the material to spread out faster, while a larger angle slows down the material's outward spread. When changing the angle of the eccentric block of the vibration motor, it should be adjusted by about 5 degrees. If you have strict requirements for screening accuracy, the angle of the motor should not be too small, otherwise the material will quickly scatter outward, which is not conducive to the screening effect. Generally, the eccentric block angle of the vibration screen is 45 degrees when it leaves the factory.
