The compacting of scraps and metal chips means a series of valuable advantages that we will try to list in this article.
Reduction of storage space
The compacting of scrap, in particular of the shavings and chips from machining, allows to reach briquette density values as high as 80% of the density of the homogeneous material. On average, in the case of steel shavings, we can consider a reduction to 1/4 of the overall volume of chips, a great reduction in the waste storage space produced by machining.
Lower environmental impact and reduction of polluting emissions
The reduction of the chips volume allows to drastically reduce the emissions of polluting gases into the atmosphere as the disposal of shavings, usually by trucks, can be less frequent. Remember that transport is the biggest sector in the ESD (effort sharing decision) with a share of 34%, and heavy-duty vehicles are responsible for around a quarter of transport emissions. Between 1990 and 2010 lorry CO2 emissions rose 36% and this increase is projected to continue. The International Transport Forum, an OECD think tank, estimates the increase of road freight emissions means freight emissions will overtake passenger transport emissions as the largest source of
Greater chip value
The lower cost of transport, due to the reduction of disposal needs, translates into an increase in the sales price of the compacted chip.
In addition, the compacted chip is subject to less atmospheric exposure than the loose chip, with a consequent reduction of its oxidation. This entails a greater yield of the briquette during the melting phase. In addition, the briquettes can be loaded more easily and fed directly into the melting furnace, eliminating the pretreatment processes to which the loose shavings must be subjected to eliminate emulsified oils residues.
Reduction of operator time
In addition to the reduction in storage space, the reduction in the overall dimensions of the chip also means a decrease in the frequency the operator must leave the work center to empty the chip collecting container. This translates into significant savings for the company and a lower risk deriving from the use of container lifting equipment.
Reduction of the residual water and oil and its recovery
During the compaction process the emulsified oils present in the shavings are almost totally eliminated and collected in the tank located on the bottom of the briquetting machine. The collected oils can be reused with consequent savings for the company.
Easier management of waste
The chips compacted in briquettes turns out to be more manageable because it is cleaner (free of emulsified oils) and because the briquettes collecting bins can be emptied more easily.
