What is the working principle of the screening machine?

The screening machine is driven by double vibrating motor, and it works on the principle of vibrating motor. When two motors rotate synchronously and reversely

At the same time, the vibration force generated by the eccentric block offsets each other in the direction parallel to the motor axis, and the screen machine overlaps into a resultant force in the direction perpendicular to the motor axis, so the motion track of the screen machine is a straight line. The two motor shafts of the screening machine have a dip angle in the vertical direction relative to the screen surface. Under the combined action of the vibration force and the self gravity of the material, the material is thrown on the screen surface and moves forward in a straight line in a leaping manner to reasonably match the screen to achieve the purpose of screening. This is the actual working principle of the linear vibrating screen.
