[0002] Linear vibrating screen, also called linear screen, is a device that uses vibration for classification and is widely used in mineral processing. Linear vibrating screen consists of screen box, vibrator, screen mesh, damping spring, etc. Its working principle is: the vibration force generated by the exciter makes the screen box produce periodic linear vibration, and the material in the screen box moves forward under the action of the vibration force and passes through the screen mesh to achieve the purpose of screening.

[0003] The vibrator is the core component of the vibrating screen. It uses a vibrating motor as a vibration source to make the material jump up on the screen and move forward in a straight line. Therefore, the adjustment of the installation angle (tilt angle) of the vibrator also directly affects the use of the vibrating screen. The screening effect of the linear vibrating screen is closely related to the tilt angle of the vibrating screen and the installation angle of the vibrator. When debugging the equipment, it is necessary not only to adjust the tilt angle of the vibrating screen, but also to adjust the installation angle of the vibrator to ensure the best screening effect.
