Vibrating screens are used to separate and classify different sizes of particles in a material. The basic principle of a vibrating screen is the vibration generated by the screen's eccentric, or unbalanced, mass, which is driven by a motor. The screen's vibration is generated by the centrifugal force of the unbalanced weight on the drive shaft. This vibration causes the material to be separated into different sizes based on the size of the particles.
The vibrating screen is made up of a screen mesh or a sieve surface, a vibrator, and a vibration damping device. The screen mesh is made up of wires or synthetic fibers, and the sieve surface can be made of various materials, such as metal, rubber, or plastic.
The vibrator is mounted on the screen's side plate and consists of a motor with an unbalanced weight attached to the end of the drive shaft. The motor drives the drive shaft to rotate, and the unbalanced weight generates the centrifugal force that causes the screen to vibrate.
As the material to be screened is fed onto the screen, the vibrating motion of the screen causes the material to separate into different sizes. The smaller particles fall through the screen's mesh and are discharged, while the larger particles continue to vibrate until they reach the edge of the screen and are discharged.
The vibration damping device is used to reduce the vibration transmitted to the ground and to the supporting structure of the screen, which can reduce noise and prevent damage to the screen.
In summary, the working principle of a vibrating screen involves the vibration generated by an eccentric or unbalanced mass, which is driven by a motor. The vibration separates the material into different sizes based on the size of the particles, and the vibration damping device reduces the vibration transmitted to the ground and supporting structure.
