VIBRATION SCREEN DEVICE, AND VIBRATION TRANSPORT DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a vibration transport device and a vibration screen device, which can reduce air column vibrations at a low cost.SOLUTION: A vibration screen device 1 comprises: a casing 5 formed with a supply port 2 and a discharge port 3 and arranged therein with a screening surface 9; a vibration generator system 6 for vibrating the casing 5; a vent hole formed in the casing 5; and an air permeable filter member for covering said vent hole. The vibration screen device 1 is constituted such that the deposit on the inner side of said air permeable filter member is enabled to fall from said vent hole into the casing by the vibrations of said casing.
