High efficiency vibrating screen working principle equipment

The bouncing screen is a kind of equipment which realizes material separation by the principle of unbalanced vibration. The following is its detailed working principle: 

The basic principle of the spring screen through the rapid vibration of the screen, so that the material on the screen surface jump forward, so as to achieve the classification and screening of different particle sizes of materials.

Specifically, when the material enters the screen body, under the exciting force generated by the vibration motor, the screen carries out three-dimensional vibration, so that the material does skipping movement on the screen. Because the screen has a certain tension, the small particle material will fall through the screen aperture, while the large particle material will continue to move forward and eventually discharge from the outlet 

The spring screen is mainly composed of feed port, screen body, screen mesh, discharge port, vibration motor and other parts. Among them, the screen plate under the action of the drive motor, through the main passive transmission mechanism composed of the drive shaft, the passive shaft, the eccentric wheel and the support base and the screen plate are connected to form an equal four-bar machine, and the screen plate produces a reciprocating circular motion similar to bouncing .

In the bouncing screen, the material according to its size, density and shape, movement on the inclined plane or collision with the inclined plane bounce, will produce different movement speed and bounce trajectory, so as to achieve separation from each other. For example, heavier, rolling 3D materials (such as plastic bottles, stones, wood, boxes, jars, etc.) and lighter, flaky 2D materials (such as plastic film, packaging bags, paper, cartons, fiber products, etc.) are separated separately, while fine materials (such as sand, organic matter, etc.) are dropped through the screen apertall.

 Adjustment mechanism In order to adapt to the screening needs of different materials, the bouncing screen can adjust the Angle of the box and the screen plate through the hydraulic jacking system, so as to adjust the bouncing lifting Angle of the sorted materials. This adjustment makes the bounce screen flexible to cope with a variety of different characteristics of the material.
