Overview
Hematite is weak magnetic associated ore. The chemical
composition of hematite is Fe *5%~*9%, S 0.*3%, P 0.2%, Si
*4.*9%, Al2O3 7.*7%. The Mohs’ scale of hardness
of the hematite is 6. The flow of the technics would be:

Â
Ore extracting and washingÂ
According to data provided by customer, the physical size of ore we are processing is no bigger than **0mm. Ore is transported to raw material storage by truck. The volume of storage should be no less than ****0 ton. The storage can be divided into three parts: raw ore storage, big size ore storage and washed ore storage. Ore is sent to raw material silo. At the top of the silo, it is a screen which can pick out ore with size bigger that **0mm. Ore bigger than **0mm will be sent to big size ore storage, while smaller than **0mm goes into the silo. There is a discharge opening at the bottom of the silo, through which the material can go into to a 2FG***0****0 double screw sand washer to be washed. Given that the ore contains soil at a content of *0%, this sand washer is necessary to remove the soil and other impurity from the ore. The output of this screw sand washer is ***0 ton per day. The washed ore is sent to washed ore storage by belt conveyor. Washed ore with size bigger than **0mm will be sent to crushing silo. Under the opening of the silo is an ***0×***0 vibrating feeder. We can adjust the vibrating amplitude of feeder to control the feeding speed. The feeder can separate the ore with size bigger or smaller than *0mm: the bigger one will be send to a crusher, smaller one to a circular vibrating screen.
Â
Ore Crushing and Storage
Washed ore and ore bigger than **0mm are sent to a jaw crusher **0×**0 for first stage crushing. The output size of jaw crusher is no larger than *0mm. The output of first stage crushing is sent to second stage crushing, two **0×***0 jaw crushers, to be crushed into size smaller than *5mm. The output of second stage is sent to a 2YK***0 circular vibrating screen, which has two layers screen, *5mm and *0mm. Rock with size bigger than *5mm will be sent second stage for further crushing. Rock with size smaller than *5mm is sent to the 3rd stage crushing, ***0×**0 hydraulic roller crusher, to be crushed into size no bigger than *0mm. Ore with size smaller than is sent to 2nd stage washing. The washed ore will be sent to a raw material silo, capacity **0t, by belt conveyors and two ***-type buck elevators. The silo should be able to store **0 ton material. We apply two flows in this plant; there should be a small silo at head of each rotary kiln. There are electromagnetic vibrating feeders at the bottom of silos to feed material into rotary kilns.
Â
Magnetizing Roasting and Cooling
Material, smaller than *0mm, is fed evenly to rotary kiln feeder by a valve feeder which is installed at the bottom of raw material silo. Then, the material is fed into 3.5m×*0m metallurgy rotary kiln. The ore reaction contains three stages: preheating, high-temp calcining, cooling. The temperature of high-temp calcining should be **0°C, and the time should be *0~*0 minutes. After the reaction in the kiln, Fe2O3 become Fe3O4, which is magnetic. The reducers of this reaction would be C and CO. And the chemical reaction formula would be: 3Fe2O3+C→(**0°)2Fe3O4+CO,3Fe2O3+CO→(**0°)2Fe3O4+CO2 . While calcining, combined water of ore escapes, the grade of ore is improved. Magnetic ore goes through a discharge opening of rotary kiln into FG***0****0 sand washer for cooling. This machine cools the magnetic ore to **0°C. After cooling, magnetic ore will be stored. The waste air come out of the rotary kiln will be purified and sent to the atmosphere. There is a tube connecting the end of rotary kiln and the coal mill, using the hot air in the kiln to dry the coal.
Â
Coal powder making and burning
Coal requirement is: heat productivity no less than ***0Kcal/kg, size smaller than *0mm. Coal is elevated into the coal silo, capacity *5 ton. There is a electromagnetic vibrating feeder, which feed the crushed coal into a 2.4×4.*5m coal mill, at the bottom of this silo. Coal is milled into powder in the coal mill. A blower press air to lift coal powder to a Type **0 powder concentrator which picks out the qualified powder. The unqualified powder will be sent back for further milling by a screw conveyor. The qualified will be sent to a ***5 dust collector by air. The collected powder is stored in a *5 ton capacity silo. Under this silo, there is a coal powder scale system, which can adjust the coal powder feeding speed. Powder and air is sent to a HNZL*2 burner buy a roots blower. The high temperature which this burner can generate is ***0°C. The tail gas of burning will go into a dust collector and the processed gas dust density is smaller than **0mg/m3 .
Â
Ore separation
Magnetic ore is conveyed to a fine crusher first. The crushed magnetic ore is then stored in a silo. At the bottom of the silo, there is an electromagnetic feeder to control the feeding speed of magnetic ore. A belt conveyor transfer magnetic ore into ***0×***0 wet type ball mill to be mill into **0 mesh. Then the slurry is send to a ***0×***0 high type classifier. Qualified ore will run into a ***0×***0 magnetic separator, unqualified will be sent back to ball mill for further milling. The magnetic separator’s magnetic density is ***0 Gauss. It can improve the Fe content in the ore up to about *0%, recovery rate about *0%. The tailing is sent and stored into a tailing pool. *0% Fe content ore slurry is then sent to the second stage magnetic separation, ***0×***0 magnetic separator, ***0 Gauss. It can improve the Fe content up to about *0%, recovery rate about *3%. The final ore slurry is send to a disc type filter 2PG***8 to dehydrate. The dry final ore contain moisture less than 5%.
The tailings will be push to a disc type filter by a slurry pump for dehydration. The dried tailings can be stored for further usage.
