Definitions

  • the invention relates to an equipment to prepare ore concentrate for pelletizing and sintering/indurating of pellets in connection with ferroalloys production.
  • FIG. 1 A prior art process and equipment for the production of ferroalloys is schematically shown in Figure 1.
  • the shown prior art process may relate to the production of ferrochrome from chromite concentrates but it can also be applied to the production of other ferroalloys .
  • the raw material is obtained from a mine.
  • the ore concentrate is stored and initially fed to the process from a day bin 7.
  • the ore concentrate has moisture content more than 1%.
  • the equipment further comprises a grinder 1 for grinding the coarse ore concentrate to a predetermined grain size which is suita- ble for the subsequent pelletizing step.
  • the grinder 1 is a wet grinder, such as a ball mill, whereto the material to be ground is fed together with the addition of water.
  • a ball mill 1 is a rotating drum which is partially filled with the ma ⁇ terial to be ground and grinding medium. Different ma ⁇ terials are used as grinding media, including ceramic balls, flint pebbles and steel balls. As the drum ro ⁇ tates the grinding media rise with the aid of centrif- ugal force along with the inner surface of the drum and eventually fall on the material to be ground. Var ⁇ ious factors, like the size of the grinding media and the rotation speed of the drum, affect to the degree of grinding.
  • the wet grinder 1 is followed by a slurry mixer 8 which is arranged to mix the slurry discharged from the wet grinder 1.
  • the slurry mixed in the slurry mixer is then led to filter 9, which can be a capillary-effect ceramic disc filter.
  • the filter 9 is arranged to dewater the concentrate slurry by filtering to form a dewatered mineral concentrate.
  • the concentrate and the additives are distributed from the intermediate bins 10 onto a conveyor 11 which con ⁇ veys these materials to a mixer 12.
  • the mixer 12 is arranged to mix the concentrate with solid fuel, process dust and binder to form a homoge ⁇ nous mixture of these. Also an amount of water can be added into the mixer 12 to ensure that the mixture has sufficient moisture content for pelletizing.
  • the equipment comprises a pelletizing drum or disc 13 which is arranged to pelletize the mixture ob ⁇ tained from the mixer 12 to green pellets.
  • the process equipment includes a roller screen 14 to ensure that uniformly sized green pellets only are fed as an even pellet bed to the endless con ⁇ veyor belt of the strand sintering/indurating furnace 15.
  • the pellet bed is exposed to subsequent drying, heating, sintering/firing and cooling steps, each of them having different temperature conditions, as the pellet bed is conveyed through re ⁇ spective zones of the furnace 15.
  • the sinter ⁇ ing/indurating furnace includes circulation gas ducts 16, 17, 18 which circulate gas from the cooling zones to the drying, heating and sintering/firing zones for the purpose of saving energy.
  • the pellets are spherical, uniformly sized, hard and porous with consistent physical and chemical properties. They are ideal charging material for ferroalloy smelting in the smelting furnace 5.
  • Reference number 19 also refers to bins for additives, like lumpy ore, coke, and quartz sand which together with pellets are charged to a preheating kiln 20.
  • the preheating kiln 20 is arranged to preheat the pel ⁇ lets before charging to the smelting furnace 5.
  • the smelting furnace 5 is an electric arc furnace. In the smelting furnace 5 the pellets are smelted and reduced to ferroalloy. The molten ferroalloy discharged from the smelting furnace 5 is casted to ferroalloy prod ⁇ ucts suitable for further production of metal.
  • the carbon monoxide rich off-gas exiting from the smelting furnace 5 is cleaned in a gas scrubber 21.
  • the cleaned CO gas is used as a fuel which is burned by a burner 22 in the preheating kiln 20 to produce the sufficient heating energy for preheating of the pellets.
  • the cleaned CO gas is also led to burners 23 and 24 located in the walls of the gas circulating ducts 16 and 17 of the strand sintering/indurating furnace 15 to heat the gas flowing in the ducts.
  • the equipment comprises a drying apparatus arranged to dry the concentrate be ⁇ fore and/or during grinding by the grinder.
  • the invention provides many advantages. By the ar ⁇ rangement of a drying apparatus to dry the concentrate before and/or during grinding by the grinder it is achieved that the concentrate can be dry ground and no subsequent dewatering by filters is needed. With the aid of the invention it is possible to cost- effectively utilize raw materials containing fine fractions which normally would be difficult to dewater by filtering.
  • the drying apparatus is arranged to dry ore concentrate by the heat energy obtained from burning carbon monoxide.
  • the drying apparatus is arranged to dry ore concentrate by the heat energy obtained from burning carbon monoxide rich off-gas from a smelting furnace.
  • the drying apparatus comprises a burning chamber comprising a burner arranged to burn carbon monoxide and/or carbon monoxide rich off-gas to produce hot gases, and a drying chamber arranged to dry ore concentrate with said hot gases.
  • the grinder comprises a grinding chamber arranged to grind the ore concentrate during conveyance the ore concentrate through the grinding chamber.
  • the grinding chamber and the drying chamber are built together, so that hot gases from a separate burning chamber are led to the grinding chamber.
  • the burning chamber, the drying chamber and the grinding chamber are built together so that the burner producing hot gases is attached di ⁇ rectly to the grinder.
  • Figure 1 shows a schematic flow chart of a prior art ferroalloys process and process equipment
  • Figure 2 shows a schematic flow chart of a ferroalloys process and process equipment of a first embodiment of the invention
  • Figure 3 shows the beginning of the ferroalloys pro- cess and process equipment of a second embodiment of the invention
  • Figure 4 shows the beginning of the ferroalloys pro ⁇ cess and process equipment of a third embodiment of the invention.
  • the raw material is obtained from a mine.
  • the raw material, ore concentrate is stored and initially fed to the process from a day bin 7.
  • the ore concentrate has moisture content more than 1%.
  • Equipment of the Figure 2 comprises a grinder 1 for grinding the coarse ore concentrate to a predetermined grain size which is suitable for the subsequent pelletizing step.
  • the grinder 1 in the invention is dry grinder 1.
  • the equipment comprises a drying apparatus into which the ore concentrate is fed from the day bin 7.
  • the drying apparatus comprises a burning chamber 2 comprising a burner 3.
  • the burner 3 is arranged to burn carbon monoxide and/or cleaned carbon monoxide rich off-gas obtained from the smelting furnace 5 with air to produce hot gases.
  • the temperature of the cleaned CO gas is about 30°C to 60 °C.
  • the resulting gas after burning comprises water, nitrogen, carbon monoxide and some oxygen.
  • the temperature of these hot drying gases is about 300°C to 500°C.
  • the hot gases are led to a drying chamber 4 which is arranged to dry ore concentrate with said hot gases.
  • the burning chamber 2 and the drying chamber 4 are separate units.
  • the drying chamber 4 may be a rotating drum which while it rotates conveys the ma ⁇ terial to be dried from the charge end to the dis- charge end.
  • the dried ore concentrate is fed to the dry grinder 1.
  • the grinder 1 comprises a grinding chamber 6 arranged to grind the ore concentrate during conveyance the ore concentrate through the grinding chamber.
