Iron ore processing line

Process Description

• 01

  Crushing the raw iron ore.

  After blasting, during the iron ore mining process, excavators and loaders transport large pieces of raw iron ore to the iron ore crushing production line. Large pieces of iron ore are evenly fed into the jaw crusher (primary crushing) through the silo by the vibrating feeder for coarse crushing; then the coarsely crushed iron ore is vibrated and screened, and then sent to the single-cylinder hydraulic cone crusher (secondary crushing) by the belt conveyor for medium crushing; the iron ore material after medium crushing is sent to the multi-cylinder hydraulic cone crusher for fine crushing. Finally, the finely crushed raw ore is screened by the vibrating screen, and the iron ore with qualified particle size enters the next stage.

• 02

  Grinding iron ore particles.

  The 0-12mm iron ore particles screened by the vibrating screen (produced by the first step-iron ore crushing-the last stage) are evenly fed into the ball mill for grinding, and the powder is screened by the post-grinding screen. Among them, the iron ore powder that does not meet the requirements is sent back to the ball mill for further grinding; the ore powder that meets the requirements of the next level of production is sent to the next section.

• 03

  Purify and remove impurities from the iron ore powder.

  The iron ore powder that meets the requirements after the second grinding not only contains the iron required for production, but also contains various other metal ores and gangue. At this time, according to the analysis materials of the original ore, the iron ore magnetic separation equipment can be used to purify the iron ore by strong magnetic separation, weak magnetic separation (such as: vertical ring magnetic separator, wet magnetic separator) and other magnetic separation.

• 04

  Drying. 

  The iron ore after the iron ore magnetic separation process basically meets the commercial demand. At this time, by drying it with a dryer, the high-quality iron concentrate required for production can be achieved.

• 05

  Water treatment.

  The whole process is equipped with a thickener, and all pollution-free system water is input into the thickener. The thickener precipitates the mud, and the precipitated water overflows into the clear water tank for reuse. The precipitated mud is pumped into the filter through the slurry, and the filter dehydrates the mud and enters the pile shed for stacking.
