How to adjust the vibration amplitude of the vibrating screen

1. Introduction to Vibrating Screen

Vibrating screen is a device that uses vibration force to separate materials on the screen. It is mainly composed of a vibrator, a screen box, a screen, etc. The vibration force generated by the vibrator will make the material move quickly in the screen box and be separated through the screen.

2. Adjust the vibration source

①. Adjust the mass of the unbalanced body

The vibration source of the vibrating screen motor is the unbalanced body, so adjusting the mass of the unbalanced body can adjust the vibration size. By adjusting the position of the weight block, the center of mass position of the vibrator can be changed, thereby adjusting the vibration size. Generally speaking, the farther the weight block is from the vibration axis, the greater the vibration force, and vice versa.

②. Adjust the vibration motor speed

The vibration motor speed is another way to adjust the vibration size. By adjusting the speed of the vibration motor, the vibration size of the vibrating screen can be changed, thereby affecting the screening effect.

③. Adjust the unbalanced body angle

When the angle of the unbalanced body is inconsistent with the angle of the motor rotor, a greater vibration force will be generated. Therefore, adjusting the angle of the unbalanced body can make the vibration stronger or weaker. The specific method is to manually adjust the angle of the unbalanced body while the motor is rotating until the desired vibration size is reached.

3. Adjust the vibration amplitude

①. Adjust the eccentricity

The amplitude of the vibrating screen is affected by the eccentricity. Generally speaking, the larger the eccentricity, the larger the amplitude. Therefore, adjusting the eccentricity is a way to adjust the amplitude of the vibrating screen.

②. Adjust the feed amount of the vibrating screen motor

The vibration amplitude of the vibrating screen motor is related to the feed amount. The larger the feed amount, the larger the vibration amplitude. Therefore, adjusting the feed amount can adjust the vibration amplitude. The specific method is to increase or decrease the feed amount until the desired vibration amplitude is reached.

③. Adjust the working voltage of the vibrating screen motor

The working voltage of the vibrating screen motor can affect the vibration amplitude. Within a certain range, appropriately increasing the voltage can increase the vibration amplitude, while too high a voltage can damage the equipment. Therefore, adjusting the voltage can adjust the vibration amplitude. The specific method is to gradually increase the voltage until the desired vibration amplitude is reached, but it cannot exceed the maximum voltage specified by the equipment.

4. Precautions

When adjusting the vibration level, pay attention to the following points:

1. Before adjustment, confirm whether the equipment is working properly to prevent unnecessary accidents.

2. Be careful during the adjustment process to prevent equipment damage or other problems.

3. After adjustment, the screening effect needs to be tested to ensure the correctness of the adjustment and the reliability of the effect.

5. Conclusion

When using a vibrating screen, the adjustment of the vibration size has a great influence on the screening effect. Through the above adjustment methods, the vibration size can be correctly adjusted to improve the screening efficiency and the quality of material separation. When operating, be sure to be careful and test the screening effect before and after the adjustment.
