我公司选矿设计能力年产33万t原矿,分两个相同系列,单系列采用1台MZSφ4000×1400湿式半自磨机与FX-350旋流器组成一段闭路磨矿流程,投产后一个月即达到设计生产能力1000t/d,磨矿细度-200目达到58%以上,铁精矿品位达到65%以上,基本满足市场铁精矿质量要求,但运行两个月后,固定 Our dressing design capacity annual output of 330,000 t ore, divided into two identical series, a single series using a MZSφ4000 × 1400 wet semi-automatic mill and FX-350 cyclone closed loop grinding process, one month after commissioning that Reached the designed production capacity of 1000t / d, grinding fineness -200 mesh reached 58%, iron concentrate grade reached 65% or more, basically meet the market iron concentrate quality requirements, but after two months of operation, the fixed
