What is the principle of vibrating screen?

A vibrating screen machine is a device used to separate materials into different sizes or grades based on their particle size. The machine consists of a screen that vibrates at a high frequency and is used to separate solids and liquids, or solids of different sizes.

The vibrating screen machine consists of a frame, a vibrating motor or drive unit, and a screen. The screen is made up of a series of wire mesh panels that are arranged in layers to provide different levels of filtration. The vibrating motor or drive unit is responsible for generating the vibrations that cause the material to move across the screen.

Linear vibrating screen

The principle of a vibrating screen is based on the movement of a circular vibrating screen. The screen works on a circular motion, which is generated by an eccentric shaft. The vibrating screen is designed to vibrate at a specific frequency, which is achieved by adjusting the eccentric weights.

As the screen vibrates, the material is separated into different sizes. The larger particles move towards the top of the screen, while the smaller particles move towards the bottom. The screen consists of multiple layers of mesh, with the size of the mesh varying depending on the desired particle size.

The vibrating screen works by applying a vibratory force to the material being processed. The force is generated by an electric motor that is connected to the screen through a series of belts, pulleys, and gears. As the motor rotates, it causes the eccentric weights to move in a circular motion, which in turn causes the screen to vibrate.
