可调式自同步概率筛的设计与研究

Design and research on the adjustable self-synchronous probability sieve

通过研究透筛概率理论,建立动力学模型和筛粒在筛面上的运动模型,得出:概率筛振幅的大小取决于偏心块的质量,振动方向角和筛体的计算质量以及抛掷指数应在3的附近选取。最后提出一种新型的裹胶变筛孔筛面,可以有效的缓解筛网的磨损、减轻筛网的堵塞。

The screening technology is reviewed,the dynamical model and the sand motion model are build to study the Probability Sieve,A conclusions is reached：the amplitude of sieve vibration is depended on the quality of eccentric block ,vibration angle and the calculated quality of screen frame and the cast index chosen around 3 is appropriate, at last,A new -style rubber-coated with hole-varied screen mesh is advanced,which can be used to relieve screen abrasion and lighten screen blockage effectively.
