中文摘要: 旋流连续离心分选机是基于旋流离心分离技术和流化床分选原理开发的新型分选设备。研究采用旋流连续离心分选机,针对赤铁矿进行分级试验,分析并确定了不同粒级赤铁矿分级的主要影响因素和最佳工艺参数。在试验研究的基础上,通过响应曲面法分析了旋流连续离心分选机工艺参数间的交互作用对赤铁矿分级效率的影响,并进行了参数优化,优化后的工艺条件为给料压力51.35kPa、反冲水压力12.14kPa、底流口压力32.27kPa,在此条件下,试验验证得到粗粒级(+0.074~-0.15mm)和细粒级(-0.074mm)赤铁矿的分级效率的平均值分别为68.19%和53.12%的良好指标,这一结果与预测值基本一致且分级效果比较好。本研究为响应曲面法应用于赤铁矿等矿石的分级提供了一定的参考和借鉴。
Abstract:The cyclone continuous centrifugal sorter is a new type of sorting equipment developed based on the cyclone centrifugal separation technology and fluidized bed sorting principle. The study used the cyclone continuous centrifugal sorter to conduct the classification test for hematite ore, and analyzed and determined the main influencing factors and optimal process parameters for different particle size of hematite ore classification. Based on the experimental study, the influence of the interaction between the process parameters of the cyclone continuous centrifugal sorter on the classification efficiency of hematite ore was analyzed by response surface method, and the parameters were optimized, and the optimized process conditions were 51.35 kPa feed pressure, 12.14 kPa backwash water pressure, and 32.27 kPa bottom flow port pressure, under which the experimental verification obtained the coarse particle size (+0.074~-0.15mm) and fine-grained (-0.074mm) hematite ore were 68.19% and 53.12%, respectively, which were in good agreement with the predicted values and had a good classification effect. This study provides some reference and reference for the application of response surface method to the classification of hematite and other ores.
