The vibratory separator is used for the classification, impurity removal, screening, filtering against corresponding material. With the application of a wide range of industries, the vibratory separator is widely used in chemical, food, medicine, metal metallurgy, and other industries. Though the screening materials are also different, the vibratory separator works basically the same way.
The working principle of the vibratory separator is to use the high-frequency vibration of the screen body to carry on a screening and grading process of the material. Although there are many kinds of vibrating screen equipment which is using the vibration motor as a power source, and the vibration motor on the body of different installation combination forms, it produces different motion trajectories. And then, let's look at their trajectories. Firstly, the circular shaker is a circular motion trajectory, perpendicular to the screen surface in the longitudinal section. The central motion trajectory is circular or nearly circular. In a word, this motion is usually produced by installing a vibratory separator.
Secondly, the vibratory separator is an inertia vibrating screen equipped with up and down eccentric block. By adjusting the angle between the eccentric blocks, the motion law of the screen machine can be changed and different technological requirements can be met. When the vibration motor rotates, under the action of centrifugal force produced by the eccentric block, the motor together with the bracket, the base, the screen frame, and the screen mesh all do high-frequency vibration. The material can be added from the top of the screen frame and discharged from the feed tube through the fine material of the screen. The coarse material that fails to pass the screen is discharged from another feed pipe. Due to the action of two eccentric blocks, under normal circumstances, the resultant force of the vibration force does not pass through the center of the vibration part, resulting in an exciting moment. In this way, the screen machine in addition to the circular shaker can do the vibration of the circular trajectory, but also for rotary motion.
Lastly, Linear vibrating screen is a double vibration motor. When two vibration motors do synchronous, reverse rotation, the excitation force generated by the eccentric block in the direction parallel to the axis of the motor offset each other. The above is the summary of three kinds of vibrating screen working principle and movement track.
