Adjusting the eccentric weight of a rotary vibrating screen requires some skill, but once you master the technique, it's not difficult. Today, let's discuss how to adjust the eccentric weight of a vibrating screen.

Adjusting the phase angle according to the material being screened:

The phase angle of the eccentric weight can be adjusted accordingly to the material being screened. For example, a phase angle of 5° allows for secondary sorting of materials; a phase angle of 15° is suitable for separating dry and wet materials; and a phase angle of 85° creates the longest path for the material on the screen, making it suitable for screening fine and micro-powdered materials. If you find that material is flowing too quickly or not flowing at all, or even jumping too high on the screen, this is likely due to an improperly adjusted phase angle of the vibrating screen motor. This can be corrected by adjusting the angle between the upper and lower ends of the vibrating screen motor. A larger adjustment angle increases the time the material remains on the screen surface, which is generally a short residence time. Excessive jumping of the material on the screen can also be corrected by adjusting the counterweight of the vibrating motor.

Steps for adjusting the eccentric block:

First, disconnect the power to the vibrating screen that needs adjustment. Secure the screen, loosen the screws with a wrench, and then adjust the eccentric block to the desired angle. Due to the limited space at the bottom of the vibrating screen, exercise caution when adjusting. If you want to increase vibration, increase the eccentric block angle. The factory setting is typically 60°. To achieve greater vibration, adjust the angle above 60°. However, be careful not to adjust it too far, as this may damage the equipment.

In daily production, rotary vibrating screens are constantly in operation. Improper adjustment can result in loosened components and long-term operation can lead to loose screws, causing a series of problems. Therefore, proper procedures and careful verification are essential when adjusting the eccentric block. We hope the above basic instructions for adjusting the eccentric block of a vibrating screen will be helpful for your operation.
