effective and no additional steps are required.
Again, scrap that would normally require gas
cutting is cheaper to buy, so eliminating gas
cutting through processing in a PC-AC opens
the path to additional profits. Any customer
buying the finished product will be happy
because they will notice the scrap is heavy and
to the required specification. It’s a win-win
solution.
For light scrap, the geometry and configura-
tion of the PC-AC feeding box, coupled with
its speed, allows high volumes of light feed-
stock to flow through the PC-AC unassisted,
and then to be processed and upgraded to a
high density because of the application of high
pressing forces. This innovative processing
method allows high density results without
resorting to cutting the scrap very short, which
is another big cost saving.

DIRT IS EASILY DETACHED
Processing results using the PC-AC are excel-
lent. The low-friction open side squeeze feed-
ing box allows both heavy and light scrap to
move forward without any energy consump-

tion; the processing zone is limited to a few
square metres; and the focus on pressing force
ensures all scrap achieves and even exceeds
the typical density requirements for today’s
market.
Heavy scrap is demolished and flattened prior
to shearing. Light scrap is pressed with such
force it also attains a heavy density prior to
shearing. A side effect of focused pressing
forces is that dirt and unwanted contamination
is easily detached from the scrap so that pro-
cessed scrap can be automatically cleaned
immediately after processing.
The PC-AC is an automatic machine that does
not require a dedicated operator. It is also pos-
sible to add additional processing steps – all
automatic – that taken together deliver a total
integrated processing system. These include
remotely operated pedestal cranes, conveyor
systems, de-dusting systems, magnetic and
eddy current separators and hydraulically driv-
en conveyors. No extra staff are required to
run a PC-AC and the plant footprint is minimal.

MANY MORE ADVANTAGES
There are fewer moving parts in a PC-AC with
only about 25% of the liner plates in compari-
son to a traditional shear, reducing mainte-
nance. PC-AC running costs are incredibly low
and it is important to keep in mind the addi-

tional savings due to streamlining of opera-
tions and elimination of scrap preparation.
Many Vezzani owners say that the introduction
of a PC-AC into the heart of their yards has
changed the way they buy scrap: they feel
they have an ace up their sleeve and can com-
pete in the most difficult market situations.
The PC-AC is the product of a long collabora-
tion between scrap companies, steel makers
and Vezzani. The end result is a shearing
machine that takes into account and addresses
the problems, needs and wishes of any compa-
ny that processes scrap metal for steel making.
It’s clear that the PC-AC is unlike any other
shear because Vezzani has listened to and
gratefully accepted the input and comments of
all the companies that use Vezzani machinery
worldwide.
