EURAGGLO and the agglomeration field: a market and an activity directly concerned by the notions of sustainable development and circular economy:
Euragglo has been designing, manufacturing and installing briquetting and compaction units all over the world since 1992. Agglomeration, which is the historical activity of our company, is a process consisting in particle size enlargement and densification carried out on finely divided solids with the use of pressure.
This process allows the recovery of by-products (fines, “wastes”…) by agglomerating them into a larger-size solid which can be reused in the production line as a secondary raw material, in order to create a “virtuous circle”. By this way, if we use the definition of sustainable development we just gave, industrial actors play on two levels: the economical one where all the secondary raw materials are totally used and reused but also on the environmental level where residues that were not recovered are substituted to primary resources.
Also, if we look at the pattern of circular economy gave by ADEME, we can see that Euragglo and agglomeration in general, are involved in several of the main pillars of this model:
- Recycling: this is one of the main principles on which the agglomeration market is based. Indeed, as we said, this activity consists in giving a second life to by-products, by recycling them under a secondary raw material briquette form.
As an example, we offer briquetting solutions for steel-mill by-products, by recovering these by-products, a priori unusable as they stand, in order to recycle them in the melting processes.
Various types of steel-mill by-products can be briquetted by Euragglo briquetting presses : mill scales, steel grits, blast furnace sludges, furnace dusts (BOF, EAF, AOD) as well as various fines such as DRI, ferro-alloys (FeMn, FeCr, SiMn, FeSi…), coal, iron oxides, coke…
And according to customer needs, steel-mill by-products can be briquetted in different sizes and shapes (pillow-square or ovoid) but the raw material should always respect some necessary characteristics to allow their briquetting (a limited moisture content – generally between 2 and 3 % – an acceptable size range…).
Before entering the rolls of the briquetting press, raw material is mixed with a binder in order to obtain mechanically solid agglomerates. After the briquetting step, briquettes are screened, a step that separates good quality briquettes that will then be stored for curing (forced or natural) and fines and flashings which will returned to the secondary raw material silo in order to be recycled into the agglomeration line. Briquettes produced are ready to be used as secondary raw materials.
