我厂采用的击振细筛,由于机械敲打装置经常产生故障,难维护,全厂11个生产系统一直未全部安装使用,至使细筛分级效率低,尼龙筛篦筛孔堵塞严重,筛上产品中含有大量的-200目粒级产品,造成循环负荷大,筛上物浓度低,影响二段磨矿效率。为了解决上述问题,我们在三系统的二段细筛机上安装了两台附着 I plant the fine vibration sieve, due to mechanical beating device often produce failure, it is difficult to maintain, the whole plant has not been installed in all 11 production systems to fine sieve classification efficiency is low, nylon sieve mesh sieve blocked serious sieve The product contains a large number of -200 mesh particle size products, resulting in heavy cycle load, low concentration on the screen, affecting the second paragraph grinding efficiency. In order to solve the above problem, we installed two attachments on the three-system two-stage sifter
