In the field of machining, the treatment
of processing waste coming from
goldsmiths and industrial processing is a
difficult aspect for companies to manage.
In fact, metal chips, whether aluminium,
brass, steel, titanium or other alloys, must
be treated according to specific rules
dictated by both legislative and economic
requirements.
Sensitive to all these aspects, Violi has
developed chip processing equipment
that allows turning the chips into almost
solid metal briquettes using hydraulic
compression technology in a small
chamber.
All compliant with the applicable
international standards, Violi’s machines
for chip briquetting are:
•
The chips and swarf hydraulic manual
briquetter model VM/CIT consists
of a container where residues are
loaded manually and compressed
by hydraulic pistons in order to get
octagonal shaped briquettes of 46
or 70mm depending on the crucible
used
•
The hydraulic automatic compactor
model VM/CTA0, suitable for small
production runs, consists of a single
piston compacting system for the
briquette production. The processing
cycle is manual and the compressed
briquette is automatically ejected
outside the machine
•
The hydraulic automatic briquetter for
metal swarf VM/CTA’s series, suitable
for medium and large production, is
composed of a chamber with double
hydraulic piston to compact the chip
which is automatically ejected outside
the machine
In order to maximise efficiency and
increase profits, chip briquetting is one
of the best solutions for the management
and resale of scrap metals. Whether
reducing the expense of handling
materials, or to turn a profit on scrap
metal recycling, Violi’s metal briquetting
presses can help your business make the
most of its scrap metals.

The rolling ring drive has been around for
decades. It is an efficient mechanism that
imparts linear motion to a carrier from
a plain rotating shaft. The beauty of the
system lies in the ability to vary pitch with
ease and for it to synchronise with line
speed when winding cable onto reels.
Originally designed in Germany, there are
now countless versions of the mechanism
produced around the world.
Marldon took a look at this mechanism to
see if it could be improved, and to remove
two undesirable side effects of the
mechanism. The unit clamps around the
shaft using springs positioned between
the carriage body and the shaft along
which it is travelling.
The carriage therefore effectively floats
along the shaft on these springs, giving rise
to unwanted movement varying with the
load applied. Some manufacturers have
overcome this by adding an extra internal
bearing, with the added cost implications.
The system must also be entirely
dismantled to effect repairs/replacements
as the body and internal components
operate as a mutually dependent set.
The solution came in the form of the
Marldon RT range of traversing units
that separate the function of carrying
the carriage on the shaft (the box body)
and the function of applying pressure
to the shaft (the spring loading). In this
system the carriage is supported on
bushes making it completely stable, and
the spring pressure is applied using a
separate spring loaded clamping plate.
The connection between the two
components allows for some float in the
non-critical vertical plane, but not in the
critical horizontal plane, so maintaining
positioning accuracy along the shaft.
