Saving Energy Concentrate Iron Ore Dressing Plant

Standard packing, Seaworthy packing

Introduction of ore dressing plant:

Ore dressing  means the production process in which the extracted ore goes through several procedures finally becomes the concentrate in accordance with the smelting requirements. Ore dressing flow mainly includes crushing by crusher, separating by vibrating screen, grinding by ball mill and classifying by classifier; the separation of minerals consists of weight, flotation, and electric separation, etc. Dehydration of minerals includes enrichment, filtration, drying, and other procedures. The equipment of mineral processing cover feeder, crusher, ball mill, classifier, vibrating screen, rocking bed, magnetic separator, mix tank, flotation machine and so on.

Working principle of ore dressing plant

The extracted ore should be crushed by jaw crusher initially. When it gets the reasonable fineness, it is transported into ball mill by elevating conveyer and feeder, and is milled by ball mill. The subtle milled ore gets the next procedure: classification. There is a theory that if the weights of solid particles are different, the sedimentations will be different, and the mixed ore can be classified by screw classifier. The classified ore gets into magnetic separator. Since the specific magnetization coefficients of ores are different, the magnetic substance of mixed ore is separated from others with magnetic and mechanical force. The mineral matter, which has been separated by magnetic separator initially, is transported into flotation machine by, and different medicines are added according to different characteristics of ore, so that the needed ore is separated from others. Since the separated ore are wet, they should be dewatered by thickner initially, and dried by drier. Finally, the dry minerals come into being.

1) The crude ore first proceed the preliminary broken; in the Stone production line, vibrating feeder can send materials to crusher evenly and continuously and at the same time, it can screen materials roughly:

2) Through jaw crusher, generally divide into coarse crushing and fine crushing two stages:

3) the appropriate stone size (10~20 mm) will be get from the last process, then will be evenly feed into the ball mill through the elevator and mining feeder, the ball mill break and grind the ore into the fine ore; then feed into the spiral classifier: 

4) Due to the gravity differences of the solid particles, their deposition rate will be different too, using this theory, the spiral classifier will wash and classify the fine ore particles:

5) The washed and classified fine ore particles will be sent to the magnetic separator, making use of minerals susceptibility differences, magnetic separator will separate the magnetic minerals from the fine ore particles mixers by the magnetic force and mechanical force, and get 65% iron ore concentrate:

6) When the flotation machine works, the motor drives the impeller to revolve, so the centrifugal effect and negative pressure are produced. On one hand, ample air is absorbed and mixed with mineral slurry, on the other hand, the mixed mineral slurry is mingled with additive:

7) Centre drive concentrator is Suitable for dehydrating water of the concentration and gangue in the concentrating factory. Make the mash of 20-30% raise up to about40-70% :

8) Ratory dryer is used for metal mining processing and drying all kinds of metal ore, leaching slag and tailings etc:
