The working principle of the vibrating screen exciter is to convert electrical energy into mechanical energy through the rotational motion of the motor, so as to make the vibrating screen vibrate. ‌ The exciter is usually composed of components such as a motor, an eccentric block and a bearing. The motor is the power source of the exciter, and the rotational motion of the motor is driven by electrical energy. The eccentric block is a special component installed on the motor shaft, which has a centrifugal eccentric effect. When the motor rotates, the eccentric block also rotates, and the centrifugal force generated will cause the entire vibrating screen to vibrate. ‌1

The key to the working principle of the exciter lies in the centrifugal eccentric effect of the eccentric block. ‌ The greater the eccentricity of the eccentric block, the greater the centrifugal force generated, and the greater the vibration amplitude of the vibrating screen. By adjusting the position and eccentricity of the eccentric block, the vibration direction and amplitude of the vibrating screen can be changed, thereby realizing the screening of materials.

‌ Exciters are widely used in industrial production, mainly in mining, building materials, chemicals, metallurgy and food industries. ‌ The vibrator has been widely used in these industries due to its simple structure, easy installation, low maintenance cost and long service life.
