The linear vibrating screen is a commonly used screening equipment in the mining industry, which is used for screening granular and powdery materials. Its working principle is based on the vibration motor as the vibration source, which causes the material to be thrown up on the screen and move forward in a straight line.

The linear vibrating screen consists of a screen box, a vibration motor, a damping system, and a support system. The screen box is made of several different layers of screens, which are arranged in a horizontal and vertical manner. The material is evenly distributed across the screens and moves in a straight line as a result of the vibration of the motor. The vibration motor generates a high-frequency vibration that causes the material to be thrown up on the screen and moves forward.

The vibration motor is usually located on the upper part of the screen box and is equipped with a vibration damping system. The damping system can reduce the amplitude of the vibration and prevent the screen box from vibrating excessively, which can cause damage to the screen box and other parts of the equipment.

The support system of the linear vibrating screen is mainly composed of a base and a support frame. The base is used to support the screen box and the motor. The support frame is used to support the base and to connect the screen box to the motor.

In operation, the linear vibrating screen can be adjusted to obtain the desired screening effect by adjusting the angle of the screen box and the vibration amplitude. The screening efficiency of the linear vibrating screen is affected by the size and shape of the screen holes, the nature of the material being screened, and the amplitude and frequency of the vibration.

In summary, the working principle of the linear vibrating screen is based on the vibration motor as the vibration source, which causes the material to be thrown up on the screen and move forward in a straight line. The linear vibrating screen is widely used in the mining industry and has the advantages of high screening efficiency, large capacity, and easy operation and maintenance.
