Over belt magnetic separation equipment is
the most reliable method to remove tramp iron. |
Efficient Removal Of Tramp Iron With Over Belt Magnetic Separators
A significant increase in the
call for over belt magnetic separation equipment has
more than validated Multotec’s strategic decision,
just over a year ago, to establish Multotec
Magnetics.
Dr Arno Steinmuller, general manager Multotec
Magnetics (Pty) Ltd, says that after five years as
the sole agent for Magnapower products, the decision
was taken to purchase the company and form Multotec
Magnetics. |
“We believe the increased demand is
as a result of the more focused approach to this sector of
the market. Together, the well known technology of magnetic
separation and the Multotec Group’s specific customer focus,
has allowed Multotec Magnetics to make substantial inroads
into the industry,” Steinmuller says.
Steinmuller explains that Multotec has a broad product
offering and the magnetic separation products fitted
perfectly into this spread. “From a supply management
perspective it is much easier for the customer to deal with
a single source of supply.
“The Multotec Group, through its extensive product offering
and philosophy of employing skilled people, also has a far
broader network in the field,” Steinmuller adds. “Including
the service factor, operating from Multotec’s customer
focussed business model has definite advantages for
customers.”
Steinmuller explains that the function of the over belt
magnetic separation equipment is the reliable and efficient
removal of the tramp iron. “It is important not to
over-specify nor under-specify the machine. If it cannot be
sized accurately then it could result in money being wasted
on a machine that is incorrectly specified.”
Steinmuller adds that, interestingly, a machine could be
over specified and still not perform adequately. “The
accuracy of predicting the probability of removing tramp
iron of a certain size and geometry relies on the accuracy
of the data being inputted. It is essential to specify a
machine that will be able to remove the sizes of tramp iron
that could potentially cause catastrophic damage to
downstream equipment within the plant.”
He emphasises that while over belt magnet technology is well
known in the industry Multotec does, however, offer some
added benefits. These include the use of customised software
to determine the most appropriate configuration of the
system for ensuring the efficient removal of the tramp iron.
“Factors taken into account during the design stage include
the physical size of the machine, the power consumption, the
orientation – cross belt or in line, for example – and the
various operational factors such as material, burden depth,
belt speed and moisture content.”
In addition to locally manufacturing the equipment, Multotec
Magnetics has an in-depth understanding of application
requirements throughout the mineral processing spectrum with
both local and international installations.
Steinmuller points to the advantage of the compact product
design. “This is beneficial when one considers that from an
economic perspective the trend today is towards smaller
footprints for plants.” The space saving design does not
compromise on the efficacy of the over belt magnetic
separation process but does allow for a far smaller
installation. This factor also plays an important role in
plant upgrades where the need exists for the effective and
efficient removal of tramp iron from the ore yet where space
is often limited.
“It is our mission to provide customers with solutions that
afford them innovative equipment solutions which will result
in both decreased downtime and ultimately, increased
productivity,” Steinmuller concludes. |
