我矿预选车间750×2300 4~#三层自定中心振动筛,担负着-150～+100、-100～+75、-75～+50三种级别矿石的分级工作。由于三层振动筛结构本身的“先天不足”,4~#筛长期处于较低的筛分效率下工作,造成较大的经济损失。针对4~#筛筛分效率低的问题,在不更换新设备的情况下,我们于83年10月对4~#筛旋转方向和进料方式作了工业性的试验,取得较明显的效果。
I mine pre-selected workshop 750 × 2300 4 ~ # three-tier self-center shale shaker, responsible for the level of -150 ~ +100, -100 ~ +75, -75 ~ +50 grade ore classification work. Due to the “inherent deficiencies” of the three-layer vibrating screen structure itself, the 4 ~ # sieves work at a lower screening efficiency for a long time, resulting in greater economic losses. For the 4 ~ # sieve inefficient screening, without replacing the new equipment, we in October 83 on the 4 ~ # sieve rotation direction and feeding methods made an industrial test, and achieved more obvious results .
