How Does Screening Bucket Work? | Screening Bucket Work Principle
The screening bucket is driven by dual-vibration motors. When the
two vibration motors are rotated synchronously and in reverse, the
exciting force generated by the eccentric blocks cancels each other
in the direction parallel to the axis of the motor and superimposes
a resultant force in the direction perpendicular to the axis of the
motor, so the motion trajectory of the screen machine for a
straight line. The two motor shafts have an inclination angle
relative to the screen surface. Under the combined force of the
exciting force and the self-gravity of the material, the material
is thrown up on the screen surface and moves forward in a straight
line, so as to achieve the purpose of screening and grading the
material.
