The vibrating screen works by using the reciprocating rotation vibration generated by the vibration of the vibrator. The upper rotating weight of the vibrator causes the screen surface to produce planar cyclotron vibration, while the lower rotating weight causes the screen surface to produce conical rotary vibration. Its vibration track is a complex space curve. The projection of the curve on the horizontal plane is a circle, while the projection on the vertical plane is an ellipse. The vibration amplitude can be changed by adjusting the excitation force of the upper and lower rotating weights. And adjusting the spatial phase angle of the upper and lower weights can change the curve shape of the motion track of the screen surface and change the motion track of the material on the screen surface.
Advantages of H&C Group Vibrating Screen：
The strong vibration of the screen box reduces the phenomenon of materials blocking the screen hole, so that the screen has high screening efficiency and productivity.
The structure is simple, and the screen surface is convenient to replace.
Screening consumes less electricity per ton of material.
The frame structure design of the screen surface adopts a mature riveted structure.
Bearing lubrication has been improved (eliminate possible assembly errors).
The spring base position has been redesigned to accommodate a lower support structure.
Larger natural frequency range, adapt to different application requirements by adjusting the exciting force of the screening machine.
Lower motor speed, using belt drive form, lower cost.
H&C Group can provide various forms of vibrating screens, including block eccentric circular vibrating screens, shaft eccentric circular vibrating screens, linear screens, drum screens, etc. Recommendations are made according to customer needs and on-site application conditions, welcome to come to consult.
