Circular swing screen can control the time of material staying on the surface very flexibly. By adjusting the tangential angle and speed, the time of material staying on the surface can be long or short, so the precision and handling capacity of material can be controlled. Swing screen installation is more convenient, fast screen change, circular swing screen in the process of material distribution on the screen is more uniform, and can easily complete screening when encounter very easy blocking material .
In the process of square swing vibrating screen, the material is strongly arranged by the inclination of the screen, so the time of material staying on the screen can not be adjusted. Compared with the circular swing screen, the size is larger and the installation is limited. The feeding port of the square swing vibrating screen is arranged at one end, one end is swinging, the other end is basically stationary, and the material is not uniformly distributed. When encounter easy blocking material, it needs to be cleaned up by bouncing ball.
