针对新开元石矿精品砂生产线的振动筛筛分效率低、处理量小,不能满足生产要求的问题,研究分析了入料粒度、形貌和水分等主要特征,并基于多因素的选型模型,分析了原筛分设备效率低、能力小的主要原因,提出了解决方案。实践表明,等面积的琴弦振动筛振动强度大,筛孔自清理能力强,不堵孔,效率高,处理量大。 In view of the problems of low screening efficiency, small processing capacity and unsatisfactory production requirements of shale shaker in XinYuan quarry fine sand production line, main characteristics of grain size, morphology and water content were analyzed and studied. Based on the multi-factor selection model , Analyzed the main reason of low efficiency and small capacity of the original screening equipment, and put forward the solution. Practice shows that the equal-area vibrating wire vibrating shaker, sieve self-cleaning ability, non-blocking, high efficiency, large capacity.
