在选矿生产和科研中,连续水析器作为小于74微米粒级物料的粒度分析已被普遍应用。和沉降法相比,它具有水析速度快和工作量较小等优点。但在使用时,分级管下面的U形导管中总会有大量物料沉积。这些沉积物料容易引起导管堵塞,给水析结果造成较大偏差。 (一) 问题出现的原因及其分析当矿粒从虹吸管进入导管后,其下降的速度为导管中水的流速 In mineral processing and research, particle size analysis of continuous water separators as fraction materials smaller than 74 microns has been commonly used. Compared with the sedimentation method, it has the advantages of fast water analysis and less workload. However, when used, a large amount of material is deposited in the U-shaped tube under the grading tube. These deposits easily lead to blockage of the catheter, resulting in greater deviation of water analysis results. (A) the causes of the problem and its analysis When the mineral particles from the siphon into the catheter, the rate of decline in the catheter flow rate of water
