Swing screen

Working principle of swing screen
Ysbd series rocking screen is a kind of low-frequency rotary vibrating screen which imitates manual shaking. Its principle is: instantaneous motion is the combination of radial displacement and circular motion (spiral motion). The vibration exciter that can adjust the eccentricity produces nonlinear three-dimensional motion, and the material also produces the same movement similar to manual operation, so as to achieve the purpose of screening. Combined with the screening accessories, the more ideal screening effect can be obtained; it is suitable for the materials with spherical, cylindrical, flaky, even irregular shapes, which are easy to block the mesh and need to be screened accurately.

Structural principle
It is designed and developed according to the principle of building block structure. It is driven by a rigid crank shaft and dynamically balanced. Driven by a rigid crank shaft with adjustable inclination angle, the circular screen body can realize three-dimensional space motion, that is, a vertical upward and downward motion is superimposed on the horizontal circular motion. The vibration parameters vary with the rotation speed, crank eccentricity, radial inclination angle and tangential inclination angle. This design structure makes the combination of working parameters infinite, so that the screened material can move on the screen layer at the desired speed or stay on the screen layer within the expected time. The amplitude and acceleration of material vary with the eccentricity of the crank. The tangential inclination angle of the crank shaft determines the speed of circular motion of the material on the screen; the radial inclination angle of the crank shaft determines the speed of the material moving from the center to the edge of the screen; the interaction between the tangential and radial obliquity leads to a spiral involute motion of the screened material on the screen The residence time of material on the screen, that is, the accuracy and measurement of screening are determined by the combination ratio of tangential and radial inclination.

Structural features
A. The pyramid base and chassis are the basic parts of the screen machine, and the middle screen layer can be increased or decreased as required.
B. The main drive shaft passes through the bearing and is fixed in the pyramid base. There are balance weights on the top and bottom of the main shaft to keep the screen machine in balance in motion. The screen machine is driven by a V-belt through a common motor.
C. The base body of the screen machine makes a kind of planetary rotation movement that revolves around the main shaft of the screen machine system and rotates around the self-propelled main shaft.
advantage
A. The material can enter from the center of the machine and pass through each layer in turn, and the material will enter the next layer from the center. Therefore, the movement distance of each part of material on the screen is basically similar. This ensures accurate screening.
B. Through reasonable adjustment of the screen machine, when the material with larger particle size is close to the edge of the sieve layer, the vertical acceleration will increase, which can further improve the screening efficiency.
