When an aluminum can of beverage is drunk up, the empty may go into the
curbside recycling bin. Then where does it go? In fact, they are recycled and
finally made into new products. Recycled aluminum has the same quality as
Recycling Process of Aluminum Cans
The consumers put the aluminum cans into a recycling bin, where they are
picked up and sent to the recycling center.
At the recycling center, the aluminum cans are sorted, washed, and
compacted into bales. The baling is completed by a metal baler. It makes the
scrap metal easy to be transported.
Aluminum bales are sent to processing plants where they are shredded into
small pieces. This makes it easier to remove the coatings on the aluminum and
helps the aluminum melt faster.
4. Magnetic separation
The shreds are then passed through a magnetic separator to remove any
traces of steel mixed in the bale.
The coating on the aluminum is removed by blowing hot air through the shreds.
If the shreds are cast into the furnace with the paint on, there will be harmful
smoke when smelting and the quality of ingot will be degraded, meanwhile
there will be an aluminum loss rate as high as 20%.
The decoated shreds are fed into a melting furnace, and heated to certain
degrees to make molten aluminum.
The molten metal is poured into molds, cools and hardens gradually to form
the ingots. Each finished ingot contains about 1.5 million recycled aluminium
cans. It is really a heavy block, isn’t it?
8. Rolled into sheets
The ingots are sent to mills where they are rolled into thin sheets of aluminum.
9. Making into new products
The sheets are then coiled and sent to manufactures who use them to make
various aluminum products, such as new beverage cans, aluminum foil and
ready meal packaging.
Beverage companies fill the cans with their product.
11. End up in Stores
The finished products end up in grocery stores. And the whole process starts
all over again. It is estimated that cans collected take up to 60 days to be
appear in the shops again.
As there are multiple participants engaged in the recycling process of
aluminum cans, there are quite a lot of business opportunities in this chain. For
those who need the metal baler and metal crusher, we can be your support.
