What is the structure principle of vibrating screen

The vibrating screen is mainly composed of the following parts from top to bottom and from outside to inside: (1) dust cover, feeding port; (2) screen frame, screen mesh, screen frame, beam ring, discharge port; ( 3) Vibration motor, vibration transmission body, upper and lower weights; (4) Vibration isolation spring, spring washer; (5) Base.

So what is the structural principle of the vibrating screen?

Through the exciting force generated by the vertical vibration motor, the rotary vibrating screen drives the movement of the upper and lower eccentric weights, so that the screen box can perform horizontal, vertical and inclined three-dimensional movements.

1. Vibration motor - Source power

The vibration motor provides the original power for the rotary vibrating screen to work, and is the excitation source of the screen machine.

2. Up and down eccentric weights - The key to operation

The exciting force generated by the vibration motor is changed by the eccentric weight to change the direction of action of the force - into three movement modes of horizontal, vertical and inclined. It is screened layer by layer and then discharged from the discharge port.

3. Spring group - Buffering effect

Since the force generated by the vibration motor will cause damage to the screen machine, adding a spring group can buffer the force generated by the motor, prevent the screen frame from being shaken, and prolong the service life of the screen machine.

4. Screen frame, screen frame, screen mesh, beam ring - The main body of screening

The screen is placed on the support structure formed by the screen frame, and the middle of the screen can prevent the balls from clearing the screen, which can not only reduce the damage of the material to the screen, but also clean the screen mesh in time. The vibrating screen can classify the materials layer by layer.
