How To Adjust The Upper And Lower Weights Of The Rotary Vibrating Screen

The working principle of the rotary vibrating screen: the vertical vibrating motor is used as the excitation source, and the upper and lower ends of the motor are equipped with eccentric weights, which convert the rotational motion of the motor into a three-dimensional motion of horizontal, vertical, and inclined. Transfer to the sieve surface for sieving. Adjusting the phase angle of the upper and lower ends can change the movement track of the material on the screen surface.

Through observation, it can be found that an additional weight block is installed on one side of the upper and lower weights (upper and lower eccentric blocks) of the rotary vibrating screen, which increases the excitation force of the screen machine. Users can increase or decrease additional weight blocks based on the number of layers and material density of the screening machine, in order to achieve a more satisfactory screening effect.

Adjusting the phase angle of the upper and lower weights

By changing the angle and mass of the upper and lower eccentric blocks of the vibrating motor, the vibrating motor can drive the equipment to generate vibration forces of different sizes, thereby changing the vibration amplitude in the horizontal or vertical direction, and then changing the flow rate and efficiency of the screening.
