- Mixers.
-
-
- Companies
involved in plastic items production and componders
know what mixers are for.
-
- Most
of recyclers don't.
-
- And
in plastic recycling, mixing is even more important
because the "raw material" is surely not
constant.
-
- Where
mixing can take place in a recycling line ?
-
- At
the inlet first; you should teach your workers to
get one bale or one box of "yellow" scraps,
followed by a green one ared and so on.
- Where
"yellow" stays for "soft", " high
MFI" or whatever different characteristics
your material have.
-
- The
recycling line will start to make some mixing and
the material at the end will be certain way more
constant.
-
- Then,
if you have rigid chips, go to a "as big as
possible" mixing silo(s) before extrusion.
-
- If
characteristics of the raw material are very different,
you may want to go with a twin screw extruder instead
a single one.
-
- And
after pelletizing, go again to a mixing silo before
packaging; this helps to get your pellets dry to
the bone and if you take a sample of the product,
go for a lab test and find it good, you'll never
have a complain.
- Ever.
-
- There
are, of course, many different mixers available
for all purposes; horizontal with fix or rotating
drum, inclined, for bulky and fluffy materails,
but we'll not go deep into the subject.
-
- There
is the right machine for any application.
