OMAR & ITR: STRATEGIC PARTNERS FOR ALUMINUM RECYCLING
Its name is ALUMIL and it builds every day the excellence in the design and production of architectural aluminum systems.
With over 30 years of experience, 2,200 employees, 32 branches, a sales network in over 60 countries around the world, 12 manufacturing plants in Europe and a production capacity of over 100,000 tons per year, it is considered one of the most advanced Groups in the world, with progressive production lines and rigorous quality controls along the entire production line.
As a leading company in this the sector in Europe, ALUMIL Group makes sure that every aspect of its production process is certified according to strict European and international regulations. Quality and respect for the environment, as well as health and safety in the workplace, are fundamental priorities in the Group.
ALUMIL acknowledges that economic growth can and must go hand in hand with a healthy and safe environment, adopting solid and specific measures for this purpose such as environmental inspections, adequate environmental training of personnel, and strategies for minimizing energy consumption, CO2 emissions, waste and reducing the exploitation of primary resources.
OMAR, which is already a partner of ALUMIL for the supply of fumes and pollutants extraction systems coming from melting processes, has recently built a new fumes extraction and filtration system for one of the Group’s factory and, through its ITR Recycling Technologies division, has also provided for a new recycling plant for scraps and aluminum profiles.
The forty years of experience of OMAR group in the foundry sector, the in-depth knowledge of this industrial sector’ s processes, the concept affinity of the two groups in terms of sustainability, through precise best practices and integrated control of processes and production, have awarded the Treviso-based company again.
In one of its European factories, the ALUMIL group needed to carry out an accurate analysis of its system for the extraction and filtration of fumes, coming from the furnace loading and slagging, in order to find solutions that aimed to improve its performance further.
OMAR, following an accurate analysis of the variables and the risks involved, has redesigned, built and installed an effective system for extraction and abatement of the fumes and for the neutralization of the acid pollutants coming from the fusion of recycled material.
The high filtration efficiency is ensured by the use of specific filter media installed in a PJ dynamic system, equipped with an automatic cleaning system. Particular attention was paid to the safety of the system, providing for a pre-abatement system for any incandescent entrainment, and the installation of ATEX certified components, according to the belonging area. The new system currently works non-stop 24h/day with an airflow of 100.000m3/h and a dusty flow at 160 ° C.
Satisfied with the construction and the service of OMAR group, ALUMIL Group has relied on OMAR’s ITR Recycling Technologies division, for the acquisition of its new treatment system for aluminum profiles scrap, in order to reintroduce it in their own manufacturing processes.
The new TSS 180 double-shaft shredder was installed first. With an hourly production of 8 tons/h, it allows the customer to perform a precise volumetric reduction and roughing of the aluminum scraps, preparing it for the subsequent enhancement and separation processes.
To guarantee full flexibility of its production system and remain completely open to the opportunities of the growing aluminum products market, the grinding line chosen by the customer is a compact mobile grinding and selection plant, complete with the mobile hammer mill HMM 100 series installed on a platform, which can be moved and lifted. It is equipped with a material separation and extraction system, that makes it easily to be repositioned according to space and production needs. The material coming out from the grinding system is conveyed to the metal separator with eddy currents SCP (Eddy-Current), which ensures an accurate selection of the shredded aluminum from the inert material.
The selected material is sent back to a special screening system for the separation of the fraction with dimensions smaller than 30 mm. Both the smaller and oversized fractions are subjected to dedicated X-ray treatment systems for cleaning and separating the ready-to-use material from any “dirty” fractions (parts with screws, bolts, zinc, …).
The aluminum scraps treatment system is equipped with a special dusts extraction and filtration system that helps to ensure the highest quality of the aluminum fractions, which have been recycled and sent back to new life.
The installed system was appreciated by the customer for its efficiency levels, versatility and maximum flexibility of use, as well as for its simplicity and affordability of maintenance operations.
The integrated, simple and absolutely intuitive management of the machines and of the system takes place via touch panel and working programs that can be memorized, according to the type of treated material. The control system was created and customized ad hoc by the software engineers of Treviso company. All of this can be perfectly integrated into 4.0 intelligent factory systems.
Finally, it is important to underline that this is a new custom-made realisation, which has been created according to the specific needs of the customer, and that qualifies OMAR Air Filtration Systems and ITR Recycling Technologies as specialist partners of the foundry industry.
