選礦廠用濕式磁選機的設計

  選礦廠在設計中, 大于1mm的碎屑初始是用位置于按照10μm脫泥的水力旋流器前面的振動篩篩除, 水力旋流器直徑為100mm;脫除的相當細的粒級排到濃縮機。高磁性的雜鐵、磁鐵礦等用雙筒低磁場強度濕式磁選機進行回收。這類顆粒如若不清理的話會積累于強磁選機的轉子里, 并造成堵塞。圓筒磁選機的非磁性產品, 再在篩孔為1mm的小型篩子上進行篩除, 作為進一步保護強磁選機的預止措施。篩下產品在緩沖槽中進行攪拌, 然后給到兩臺頭一段強磁選機, 頭一段強磁選機的非磁性產品, 進入水力旋流器, 以便進行濃度控制;然后再經過掃選強磁選機, 進一步進行回收赤鐵礦。頭一段強磁選機與掃選強磁選機的磁性類產品進入到水力旋流器, 并在皮帶過濾機里進行脫水。由于強磁選機回路只是整個選礦廠的一小部分, 因此規定每個送到強磁選機的給料料流須接到尾礦濃縮機, 以使選礦廠的這一部分在回路中的各段濕式磁選機投產、維修或停止運轉時能被旁路。
