Conveyors - Bunting Magnetics - Plastics
Protect Your Investment in Machines, Material, and Markets
Bunting® Magnetics Co. can
keep your plastics operation
running smoothly and
productively. We offer an
exceptionally complete line of
magnetic metal separation
equipment and electronic
detector-separators designed to
remove all types of metal
contaminants from virgin resins,
regrind, and recycled plastic
material.
Our separators are engineered
for easy installation and long,
trouble-free service in
mechanical, gravity, or
pneumatic conveying systems.
Bunting® Separation Equipment
provides continuous protection
with little or no maintenance.
You can select from a wide range
of options and order
construction grades to match
your requirements.
You can trap tramp metal even
before it reaches your storage
silo by installing a Bunting®
Pneumatic In-Line Magnet and FS
Metal Detector-Separator in the
conveying line from your
unloading area. Under silos, use
a Bunting® HF Drawer Magnet.
Drawer Magnets with multiple
rows of staggered magnet grates
are especially thorough at
removing tramp iron. High-energy
Rare Earth magnet loads are an
option on these and other
Bunting® Separators.
To save labor, many Bunting®
Magnetic Metal Separators are
available in self-cleaning or
pneumatic self-cleaning models –
and all offer the constant
protection of permanent magnetic
power. Bunting® Pneumatic
In-Line and Center Flow Magnets
are ideally suited for use in
pneumatic conveying. Our
electronic FS Metal Detector
rejects both ferrous and
nonferrous metal debris in
pneumatic lines.
Additional protection is recommended at the infeed of blow molding, extruding, molding and hot runner equipment, in particular. The Bunting® electronic LCS and Quicktron 03R Detector-Separators mounted on the five processing machines sense and separate all common metal contaminants, such as iron, stainless steel, brass, copper, tin, lead, and aluminum. Rearrange metals to suit column width. Fast reject mechanisms minimize the loss of good material.
For protection against metal contamination, Bunting® Grate Magnets can be placed inside supply hoppers, and FF Drawer Magnets can be mounted above feed throat openings. FF Drawers are ruggedly built, offer self-cleaning and many other options, and let operators visually monitor material flow.
The hot runner system is equipped with a Bunting® FF Double-Row Drawer Magnet and a Quicktron 03R Detector that rejects both ferrous and nonferrous fines down to 0.4 mm in diameter to keep gates metal free. The molding machine to its right is set up for Just-In-Time operation and features a Bunting® Torpedo Magnet suspended in the glass sight tube where its Rare Earth cartridge is in direct contact with the material flow.
The extruder uses the double-row FF Drawer Magnet mounted between the hopper and the extruder throat. If overall height is an issue, the Torpedo In-Line Magnet can mounted between the gaylord and the vacuum loader. A Bunting® Plate Housing Magnet can be used for material that is not normally free flowing and would not be captured by the FF Drawer Magnet. It has a very high flow capacity and is available in standard and pneumatically powered self-cleaning models. The LCS Detector provides the all-metal barrier.
