Description Swing screen is a special equipment for wood chip preparing section, mainly used for sorting different size wood in production process, and the sorting specification can be realized through changing different mesh size of the screen mesh Working principle The eccentric shaft was driving by the motor to rotate through the triangular belt, and the eccentric distance of the eccentric shaft is the swing range, and the swing amplitude can be adjusted by the bolt; the screen frame is swing driving by the upper parts of the eccentric shaft through a self-aligning bearing. When the wood chips falls into a screen body, due to the screen body tilted by an angle, with the body to swing, chips falls down and sorting through the screen, chips of different specification discharged by different port output. Feature Widely used in wood preparation screening section such as paper making, particieboard, fiber board industry . The series sieve with oscillating balance, low noise, long service life, the screen is easy to change, etc.
