A vibrator with eccentric force makes the screen vibrating.

Model Number: self-centering vibration screen Brand Name: CHMM Key Specifications/Special Features: A vibrator with eccentric force makes the screen vibrating.The material in the screen can be loosed and layered under the vibrating; the balance-weight of the screen can be adjusted, and the vibrating amplitude can be adjusted as well according to the production requirement; While the feeding changes, the vibration amplitude will change as well.While feeding is smaller, the vibration amplitude will be higher; while the feeding is more, the vibration amplitude will smaller.The feeding change will affect owner balance thus cause the belt wheel center vibration; the self-centering vibration screen operation is stable, its vibration amplitude is bigger than the amplitude of inertial vibration screen, the vibrating efficient can reach more than 80%.The self-centering vibration screen is used in mine, coal, metallurgy, building material and chemical industries, for classifying medium size material, not suitable for screening rough material.al.Working principleA self-centering vibration screen consists of screen frame, screen surface, eccentricblock, eccentric driving shaft, bearing and spring etc. its working principle is similar with the same as popular screen. Especially that the central position of the belt wheel will not change. While the self-centering vibration screen is working, the screen will vibrate up and down at the action of eccentric shaft, while the offsetting of the eccentric shaft moves upward, the screen will move upward, meanwhile produce upward inertial force; on the contrary, while theoffsetting of the eccentric shaft moves downward, the screen will moves downward, meanwhile produce downward inertial force,which makes the overall screen vibrating. In order to remain the vibration screen steady, while the offsetting moves upward, the eccentric block will move downward; While the offsetting moves downward, the eccentric block moves downward; While the offsetting moves downward, the eccentric block moves upward, the inertial force produced by the both is the same, the direction is opposite, the moving distance of the screen up and down is equal the offsetting of the eccentric shaft. At this time the space of trough belt wheel on the eccentric shaft is not changed, so it’s named self-centering. While the balance mentioned above cannot realize, should adjust the radial position of the eccentric block,which can remain the position of the trough belt wheel unchanging, reach the self-centering purpose.
