介绍了大型弧线振动筛的基本机械结构和筛面的运动特性,即采用动力学对称平衡机构，筛子工作时仅筛面振动，筛箱和机架不参与振动，对地基的动负荷低。采用大振幅、大振动强度和较低频率，获得较好的脱水、脱介效果。
The basic mechanical structure and the movement characteristics of the screen surface are introduced. The symmetrical balancing mechanism is adopted. When the screen works, only the screen surface vibrates. The screen box and the frame do not participate in the vibration. The dynamic load on the foundation is low. With large amplitude, large vibration intensity and lower frequency, better dehydration, de-mediating effect.
