Definitions
- the invention relates to a process for agglomerating industrial dusts, in particular by briquetting technique.
- industrial dusts are understood to mean: dusts and / or fines from foundries, steelworks and blast furnaces rich in metal oxides, especially from dust collection systems, as well as dust or fine residues from oxycutting and other cutting work and sludge from the process and / or lagging.
- Agglomeration is a process that is based on the adhesion of the particles together to obtain agglomerates of larger size.
- the invention relates to the second of these two technologies.
- a binder is a high viscosity or hydraulic material (eg cement) applied so as to impregnate the dust in order to ensure the cohesion of these in the form of briquettes and to give the grain a mechanical strength sufficient to withstand the vibrations and to the movements to which he is subjected during his various manipulations.
- a binder is a high viscosity or hydraulic material (eg cement) applied so as to impregnate the dust in order to ensure the cohesion of these in the form of briquettes and to give the grain a mechanical strength sufficient to withstand the vibrations and to the movements to which he is subjected during his various manipulations.
- WO96 / 39290 discloses a multi-stage briquetting method of mixing the dusts with a carbon source (coke) whose role is heat transfer at the time of melting, with also a mixture of polymer and inorganic salts (calcium carbonate and alumino silicate), then to add to the product obtained, an emulsion of a polyvinyl polymer before an ultimate compression step.
- a carbon source coke
- a mixture of polymer and inorganic salts calcium carbonate and alumino silicate
- the present invention aims to overcome these disadvantages.
- It relates to an industrial dust agglomeration process consisting of: - mixing in a tank the dust to be agglomerated in the presence of a first binder comprising a polymer of molecular weight greater than 500,000 g / mol in the form of an inverse emulsion, then to add separately in the tank while kneading, a second binding agent comprising an alkali metal silicate, finally to compact by pressure, the agglomerates obtained.
- the method of the invention is carried out in the absence of exogenous water supply, that is to say in the absence of water supply other than that provided by the active ingredients. This is for example the case of silicates which are formulated in aqueous form.
- the dust may be limed or not.
- the dust mixing time with the first binder is between 30 seconds and 5 minutes.
- the mixing time of the mixture obtained in the first step with the second binder is between 1 minute and 10 minutes.
- the main object of the invention is to provide briquettes which have surprisingly improved properties compared to aggregates of the prior art.
- the briquetting process according to the invention is based on the agglomeration of industrial dusts in the presence of a combination of two specific binders.
- the invention makes it possible, during the recycling of these agglomerates, that no substance detrimental to the industrial process, such as sulfur, is provided by the briquettes thus obtained.
- the polymer be added before the silicate.
- the mixing is carried out in a suitable mixer or solid mixer for which the skilled person will be able, by his own knowledge, to determine the conditions necessary for the mixture to be as homogeneous as possible.
- the mixture thus produced is then sent to a press to give it a defined shape.
- Briquettes also called balls
- They are made by compression molding. They can be of different sizes. Once obtained, they are then transferred to a storage area.
- Another object of the invention is the use of the agglomerates defined above for recycling the dust and / or fines of foundries, steelworks and blast furnaces, rich in metal oxides, as a complementary filler in fusion apparatus .
- the briquettes may contain a proportion of reducing agent to allow the conversion of metal oxides to metal so that it is not necessary to add to the melt .
- this polymer can also be branched.
- a branched polymer is a polymer which has on the main chain branches, groups or branches, arranged generally in a plane. The branching may preferably be carried out during (or possibly after) the polymerization in the presence of a branching / crosslinking agent and optionally a transfer agent.

- the high molecular weight polymer of the invention is characterized in that, in use: it is in the form of an inverse emulsion, namely water in oil, it has a molecular weight greater than 500,000 g / mol and up to 20,000,000 g / mol, and the weight ratio (dry polymer / oil) of the emulsion is between 0.15 and 1, preferably between 0.3 and 0.8, advantageously of the order 0.5.
- This weight ratio can be obtained either directly during the polymerization of the emulsion polymer, or by the addition of an oil to the emulsion such as polymerized just before its use.
- the weight ratio is achieved by adding an oil, it must be compatible with that of the emulsion and not cause destabilization.
- the concentration of the polymer to which it is injected into the kneader is between 5 and 20% by weight.
- the high molecular weight polymer is an anionic copolymer based on acrylamide and acrylic acid salts, having anionicity of between 10 and 50 mol% and a molecular weight greater than 5,000,000 g / mol.
- inverse emulsion referring to the polymer used according to the invention, the skilled person will understand that is designated the water-in-oil inverse emulsion undissolved in water before its introduction in the mixer.
- This inverse emulsion may preferably be of standard type or possibly microemulsion type, which is distinguished from standard emulsions by smaller particle sizes (of the order of 0.1 micrometer).
- the inverse emulsion polymer ratio can range from 0.2% to 1% by weight, and is preferably between 0.2 and 0.5% by weight. It should be noted that throughout the description and claims when referring to ranges of values, the terminals are included. Of course, the optimum amount will depend on the nature of the particles and the properties required.

- the silicate represents between 2 and 5% by weight of the agglomerates formed and the high molecular weight polymer represents from 5 to 40% by weight of the silicate.

- This mixture is limed then deposited in the mixer (capacity: 2 tons).
- the peculiarity of this briquetting mixture is the hydrophobic character of the powder due to the presence of hydrocarbons. This characteristic is very important to take into account from the chemical point of view: the binder must have an optimal affinity with the powder, in order to obtain an intimate mixture in the kneader and a maximum adhesion force during the briquetting phase.
- the binders are then added and mixed in the following sequence: the high molecular weight polymer is added as an inverse emulsion first, via a fully manual compressed air pump. The addition is made by opening the compressed air valve for a given time, after a mixing time, adding the silicate binder via a volumetric pump equipped with a mass flow meter.
- the time between the introduction of the binding agent (s) into the mixer and the outlet of the mixture to the compactor is equal to 5 minutes.
- the equipment used in the tests is a drum compaction machine.
- the operating pressure is of the order of 100 bars.
- the binding agents used are those conventionally used by industry, namely molasses and lignosulfonate. They have the main disadvantage of introducing sulfur into the steel, which will have the effect of weakening it.
- the first (or only) binder is introduced.
- Test aspect of the ball visual test, the ball must be well formed, the shape is a rectangular pebble. A smooth exterior appearance and effective entanglement (no millet formation) are required.
- Fine return tests After sieving the pellets at the outlet of the compressor, the return fines are placed aside for weighing; The ratio is • Mass of return fines / total mass of the batch (2 tonnes) expressed in%.
- Ball hardness test Manual press with variable pressure on the ball, the test ends when the ball splits and / or bursts. This test is performed on balls after 2 hours and after 24 hours. The hardness is expressed in kg / ball (weight necessary to break the ball). The higher the number, the better the shots are. It should be noted that 250 kgs is the upper limit of the manual test, this limit being perfectly validated for an excellent quality of the ball.
