摘要
由于原重介浅槽分选工艺中的末原料无法进行分选,且筛分效率低,经对比后提出优化方案如下:将博后筛改为驰张筛,进行 6mm脱粉,200-6 mm仍采用原有重介浅槽系统进行分选,新增-25 mm粒级精末料离心机.优化后,筛分效率为 90%,达到预期效果;水洗系统处理量可达 700 t/h,密度为 1.67 g/cm3,精料中带矸 0.7%、矸石带泥0.9%,此外,分选数量效率高达99.0%,表明优化分选工艺的切实可行.
Abstract
Due to the inability to separate the final raw materials in the original heavy medium shallow channel sorting process and low screening efficiency.After comparison,this paper proposes an optimization plan as follows:Changing the Bohou screen to a rotary screen for 6 mm powder removal,still using the original heavy medium shallow channel system for sorting 200-6 mm,and adding a-25 mm particle size fine particle centrifuge.After optimization,the screening efficiency is 90%,achieving the expected effect.The processing capacity of the water washing system can reach 700 t/h,with a density of 1.67 g/cm3.The concentrate contains 0.7%gangue and 0.9%sludge.In addition,the efficiency of sorting quantity is as high as 99.0%,indicating the feasibility of optimizing the sorting process.
