screen vibration system for asphalt-concrete gravel sorting

摘要

PURPOSE: A screen vibration system for sorting asphalt-concrete gravels is provided to facilitate the control of vibration width in order to enable variation of a weight included in a rotary shaft. CONSTITUTION: A screen vibration system(100) for sorting asphalt-concrete gravels comprises a screen member(110), protection element(120), vibration generating unit(130), and rotary power transfer pulley(140). The screen member comprises a plurality of screen networks(111). The protection element comprises a bearing(121), a bolt and a nut. The vibration generating unit enables the variation of vibration width. The rotary power transfer pulley transfers the torque to the vibration generating unit.
