Definitions
- the invention relates to a process for the production of ore with a fines, aggregates and optionally a binder-containing green agglomerates, which are provided with a fine-grained carbon-containing fuel, such as coke, and optionally a binder, formed casing, wherein the ore with the Aggregates and the optionally present binder is mixed, the mixture is pelletized and the green agglomerates thus formed are coated with the addition of the fuel in an agglomeration drum with the fuel, and a plant for carrying out the method.
- a fine-grained carbon-containing fuel such as coke
- a binder formed casing
- pelletizing plates have only a limited capacity, i. it is for a larger and more efficient system to provide a plurality of pelletizing plates, whereas it is sufficient to provide with a single agglomerating drum for wrapping the green agglomerates formed in the pelletizing plates.
- the coupling of the plurality of pelletizing plates with a single agglomerating drum is expensive, especially since a conveyor must lead from each of the pelletizing plates to the agglomerating drum. In this promotion, it may lead to the destruction of part of the green agglomerates formed.
- the invention aims to avoid these disadvantages and difficulties and has as its object to provide a method and a system for carrying out the method, which ensure a uniform and continuous process of producing the green agglomerates.
- the process should require only a little complex system for large throughputs per unit time. It's a special one Object of the invention, a change to different modes of operation - caused by different Feinerzzusammen GmbHen or different additives, etc., - To allow in a particularly simple manner.
- This object is achieved in a method of the type described above in that the mixture is pelletized in the Agglomeriertrommel and the fuel is added at a region of the longitudinal extent of Agglomeriertrommel at which forming in the Agglomeriertrommel green agglomerates for further processing have desired size.
- a particularly simple adaptation of the method according to the invention to different modes of operation, different ores, different ore compositions, etc., is characterized in that the addition area of the fuel into the agglomerating drum is varied over the length of the agglomerating drum depending on the nature and size of the green agglomerates.
- a plant for the production of ore with a fines, aggregates and optionally a binder containing green agglomerates, which are provided with a cladding containing fine-grained carbon, such as coke, which plant a mixer for the ore, the aggregates and optionally existing binder, which is arranged downstream of a pelletizer, is characterized in that the pelletizer is designed as an agglomerating drum, which is provided at an area within its longitudinal extent with an addition device for the fuel.
- a preferred embodiment is characterized in that the addition device is variable while changing the region of the longitudinal extension at which it discharges the fuel into the agglomeration drum.
- the feed device is designed as a conveyor belt protruding into the agglomerating drum, wherein expedient the conveyor belt speed is variable or the position of the conveyor belt relative to the longitudinal extension of the agglomerating drum and thus the delivery area of the conveyor belt is variable.
- the conveyor belt speed is variable or the position of the conveyor belt relative to the longitudinal extension of the agglomerating drum and thus the delivery area of the conveyor belt is variable.
- conveying screws or chain conveyors protruding into the agglomerating drum, which preferably can also be brought along in the longitudinal direction of the agglomerating drum.
- the mixer is expediently designed as a horizontal or vertical shaft mixer with blades arranged on the shaft or on the shafts.
- the mixer with the agglomerating drum is formed ingetral, so that as soon as the ore is mixed with the additives and the optionally present binder, a direct transition takes place in the Agglomeriertrommel, whereby no own conveyor from the mixer to Agglomeriertrommel is required.
- the region of the longitudinal extension at which the feed device for the fuel admits it to the agglomeration drum lies between the first third and the last quarter of the longitudinal extent of the agglomerating drum, preferably between the half and two thirds of the longitudinal extent of the agglomerating drum.
- FIGS. 1 to 4 each illustrate a variant in a schematic flow chart representation.
- ores and aggregates, wherein also fuel, e.g. Coke can be present as an additive, taken from bunkers 1 arranged side by side and from these to a conveyor, such as a conveyor belt 2, which conveys these materials to a mixer 3, which is preferably installed express as a high-performance mixer, as will be described later.
- the materials are additionally added via a feed 4, a binder, such as quicklime added.
- a binder such as quicklime added.
- water is added via a supply line 5 in a specific amount to optimize the mixing process and also the agglomeration process to be carried out subsequently in order to obtain a certain optimum moisture content.
- the mixture discharged from the mixer 3 passes via a conveying device, such as a conveyor belt 6, to an agglomeration drum 7 in which the mixture is granulated and in which the required final moisture is also adjusted via a water feed 8.
- the material passes from one feed end of the agglomerating drum 7 to the opposite discharge end, with increasing formation of green agglomerates, which are finally preferably to have a size between 2 and 8 mm, from where they are further requested for further processing.
- Such further processing is preferably carried out by sintering in a belt sintering plant.
- the agglomerating drum 7 is arranged in the illustrated example in a horizontal position; However, it can also be arranged slightly inclined to increase the capacity. This also applies to the mixer 3, if this is designed as a drum mixer or high-performance mixer.
- the green agglomerates - so-called green pellets - are obtained with their fine grain size upon reaching their optimum particle size, preferably fine coke, coated.
- This adding device 9 is preferably designed as a conveyor belt whose discharge point 10 determines the region 11 to which the fuel is added to the green agglomerates.
- the task of the fuel on the conveyor belt 9 is via a bunker 12, a weighing belt 13 and a feed chute 14.
- the fuel may be provided with a fine-grained binder, e.g. with quicklime, hydrated lime or blast furnace slag with glassy structure.
- the conveyor belt 9 preferably projects into the agglomerating drum 7 via one end thereof and extends in the longitudinal direction of the agglomeration drum 7.
- the area 11 of the discharge of the fuel ie the area of the first contact of the fuel with the green agglomerates, variable, which can be accomplished by changing the conveyor belt speed, so that the Abschparabel for the fuel is changed.
- This can also be done by moving the conveyor 9 in Longitudinal direction of the agglomerating drum 7 can be achieved, as illustrated in the drawing by a double arrow 15.
- the particular advantage of the invention lies in the fact that the green agglomerates are stabilized in their shape immediately after they have been formed, specifically by the jacketing with the fuel taking place immediately thereafter.
- This means that the green agglomerates are not affected by a pelletizing regime, e.g. a pelletizing plate to a Brennstoffummantelungs worn, which is either also designed as a pelletizing or agglomerating drum, must be required. Since the green agglomerates are coated with fuel immediately after they have reached the correct size within the agglomerating drum 7 and are not subjected to intermediate conveying, accurate graining of the green agglomerates is to be achieved and destroyed as they are take place at an intermediate promotion, reliably avoided.
- the invention thus makes it possible, in a particularly cost-effective manner, to process sintered raw mixtures with a high fines content into relatively coarse green agglomerates.
- the grain size of the green agglomerates can be easily adjusted according to the invention by changing the range of contact of the green agglomerates with the fuel within the length of the agglomerating drum 7.
- the coated green agglomerates thus formed have good gas permeability in a sintering machine, whereby high productivity of a sintering plant can be achieved.
- the improved permeability also makes it possible to minimize the consumption of electrical energy in a sintering machine.
- the sinter thus produced then has a high and stable quality and e.g.
- the mixer 3 is formed as a high-performance mixer, namely, this has a horizontal, driven Shaft 16, on which radially outwardly extending blades 17 are arranged.
- the use of such a high-performance mixer lowers the humidity of the green agglomerates to a minimum value, whereby an additional increase in productivity can be achieved on a sintering machine.
- the materials in the mixture are distributed particularly homogeneously, whereby a uniform quality of the final product is ensured.
- the mixer 3 is integrally formed with the agglomerating drum 7, i.
- the mixture is introduced via the conveyor belt 2 directly into a drum, the first part of which acts as a mixer 3 and the further part of which acts as agglomerating drum 7, in which the addition of fine coke also takes place.
- the agglomerating drum 7 is also integrally formed with the mixer 3, but the agglomerating drum 7 is fixed, i.e., fixed. stationary, is arranged on the foundation and at least one shaft 16 is arranged with blades 17 inside the Agglomeriertrommel. This shaft 16 with blades 17 also passes through the mixer 3 and is drivable.
- the feed device 9 opens into the agglomerating drum 7 via an optionally placeable opening 18.
- mixing as well as agglomeration as well as sheathing takes place in a single device-a mixed agglomerator-meeting the different mixing, agglomeration and sheathing requirements different design of the blades 17 in the individual areas of this Agglomeriertrommel 7 is taken into account.
- 40% of the used grains of an iron ore to be processed have a size of less than 0.125 mm.
- the humidity is 3 to 4%.
- the materials introduced into the mixer 3 are added to water in the mixer, so that the moisture content of the mixture produced is between 5 and 6%.
- the mixture thus prepared is introduced into the agglomerating drum 7, which additionally 8 t / h fine coke with about 10% moisture and a grain size less than 1 mm are supplied.
- the grain size of the green agglomerates is between 2 to 8 mm.
- the ore-green agglomerates produced in this way are outstandingly suitable for sintering as a result of the good permeability of these green agglomerates.
- the invention is not limited to the production of green agglomerates from iron ore, but is also applicable to non-iron ores such as e.g. Lead ore or manganese ore applicable.
