摘要
以东鞍山红矿为原料,研究了水力旋流器结构参数对分级过程的影响。优化选择了125mm水力旋流器的结构参数,获得了水力旋流器溢流中-200目含量达95%、分级量效率超过80%、分级质效率最高可达75%以上的良好分级指标。分级效率的提高,可减少因合格粒级返回球磨机而产生的过粉碎,为改善后续选别作业的效果创造了条件。
The effect of the hydrocyclone structural parameters on the classification process was studied with Donganshan hematite ore as the raw material.The structural parameters of 125mm hydrocyclones were optimized and good classificatoin performances were achieved.The -200mesh content in hydrocyclone overflow reached 95%,the quantity efficiency of the classification was over 80% and the quality efficiency was up to over 75%.The improvement of the classification efficiency can reduce the overgrinding due to the recirculation of the undersize fraction to the ball mill.As a result,good conditions can be created for improving the separation performances of the downstream operation.
