The growing awareness of the mismanagement
of hazardous e-scrap processing in third world countries, as
well as other factors, has resulted in an increased demand for
safe processing of e-scrap in the United States. Part of that
process typically involves conveyor machines during the sorting
and recycling of e-scrap.
Gary St. Charles is assistant general manager
at Endura-Veyor Inc. (EVI). The company focuses on loose and
scrap material handling conveyor designs. “Due to some potentially
hazardous material within e-scrap, I think we’ll see an increase
in related government agency policies. Europe has been a leader
in controlling the undesirable exporting and processing of e-scrap,
and I believe that a majority of e-scrap processing equipment
purchased in the United States is imported from European manufacturers.
As electronic device usage continues to increase, our country
seems to focus more than ever on keeping e-scrap out of landfills
and recycling materials instead of producing new,” St. Charles
EVI has aided their clients in processing
over 100 million pounds of electronic waste in 2010 and they
expect to double that amount this year.
St. Charles explained, “Endura-veyor’s 600
and 300 conveyor products are often the best fit for the job.
The conveyor configuration can be matched to the system layout,
meeting the specific design needs of sorting, shredding, chopping,
granulating and mechanical separation processes that are common
in e-scrap processing. If a conveyor system isn’t properly sized
for a given process, it may result in added cost due to conveyor
failure and lost production, repairs or a compromise in the optimal
layout of the processing area.”
EVI’s hinged steel belt conveyor, available
in 2.5”, 4”, 6” and 9” sizes, “is rugged, dependable and ideal
for handling typical e-scrap items such as cell phones, refrigerators,
CRT cullet and ‘meatballs’ or other scrap metal handling processes.
Our Sliderbed Belt Conveyors are designed specifically for handling
various types of loose scrap, and offer maximum product containment
and ease of maintenance,” said St. Charles.
Traditional horizontal and inclined designs
are available, as well as C&Z styles, which transition from horizontal to incline
using a single belt. The conveyors can be designed for use in
conjunction with all types of overhead separating magnets and
metal detection equipment.
Mayfran International is a manufacturer of
conveyors and recycling equipment components. Their full line
of durable hinged steel belt conveyors and systems handle metal
scrap, paper and municipal solid waste. “We’ve been known as
the standard for baler feed conveyors for over 75 years. Mayfran
light-duty conveyors are for lighter materials like paper for
baler feed, and we also offer extreme-duty, reinforced conveyors,
which handle heavier materials. Heavier-duty conveyors offer
reinforced belts, an electronic-drive soft-start for repeated
start-stop baler feed operation, an open-frame, reinforced construction
and an anti-rollback device, which allows for heavier loading
and variable speed drives for various commodities,” said Bernard
Goldstein, chief engineer.
He stated, “Our clients require conveyors
that take abuse with minimal maintenance, and they need conveyors
and systems that are easy to install on-site. We believe we provide
these features in our products. We also strive to reduce overall
maintenance requirements and provide custom conveyors at standard
conveyor lead times, all while meeting the demands for lower
up-front costs in today’s tough economy. We can also include
system flexibility whenever needed, for constantly changing material
Goldstein said that automation is the newest
trend in recycling systems, allowing many manual labor tasks
to be replaced, but Mayfran has also built MRF systems designed
for teams of sorters to pick various grades of plastics, glass,
etc. The conveyors handle a mixed stream of materials that feed
trommels, shredders, shakers, electro magnets and other sorting
equipment. For electronic controls and monitoring of a conveyor,
Mayfran recommends and installs remote interface capability,
which allows offsite access to system controls.
Remcon Equipment offers complete conveyor
systems as well as components for use in an existing system,
such as individual conveyors, material separation equipment (screens,
magnets) and storage structures (silos, self-emptying bins).
Most features of the equipment can be customized to fit customer
needs regarding factors such as belt speed and type, conveyor
width and length, hopper and chute designs, etc.
“Because we customize our conveyors to each
customer’s specific application, we can incorporate design features
that keep material leakage to a minimum,” said Dennis Lux, president.
He added, “We also keep the maintenance crew in mind by designing
conveyors for cleanliness, safety and for easy access to maintenance
areas. Another service we provide is conveyor belt replacement.
A good conveyor will be built to last longer than needed, but
belts eventually wear out or become damaged beyond repair, no
matter what the belt type or the material that is being processed.
We also provide customized replacement belts and installation
for other brands of conveyors.”
Lux said that Remcon products are used primarily
by customers for sorting recyclable materials. “Most of the units
we manufacture are slider bed, drag or roller chain conveyors.
Baler feed and sort line types are also popular. Many large recycling
companies install huge, multi-million dollar systems to process
incredible volumes of material, but there are also many small
operations out there that need simple, easy-to-operate machinery.
We can design whatever is needed. Instead of just offering a
few standard, light-duty conveyors for smaller scale operations,
we take the time to design heavy-duty, custom built conveyors
for these customers, while keeping extraneous costs to a minimum,”
Remcon has built conveyors since 1977 and
according to Lux, “We design conveyors that are easy to maintain,
run clean, and are heavy-duty enough to handle the harsh environments
that are typical at recycling facilities and landfills. We always
keep installation capabilities in mind during the design process,
and we strive to incorporate easy-to-replace components. Over
the last seven years, we’ve manufactured high-speed conveyors
for use in conjunction with optical sorting equipment. These
conveyors require a much higher degree of specialization due
to the speed and precision of the process. As technology advances,
the materials and production methods used to put this technology
into operation will also need to improve, and we look forward
to seeing that come to fruition."
