Viable Cost Effective Option To Product Collection On Spiral Banks
Multotec has launched a
lightweight polypropylene product collection launder
designed to achieve effective and efficient
channelling of spiral products.
“Wear is a major issue in spiral product
applications, and wear characteristics were one of
the primary factors considered during the design
phase of the new polypropylene production collection
launder,” Rohan Young, production superintendent at
Multotec Process Equipment, says. |
Multotec Process Equipment
identified the need for an innovative solution, and that
materials of construction available, such as fibreglass and
HDPE, do not achieve the desired wear characteristics and
impact on the life cycle of the product itself.
The new product collection launder has an integral cast
polyurethane lining as opposed to a sprayed lining. This has
given this product an above average and consistent wear
lining characteristic. The method of manufacture ensures a
consistent polyurethane lining thickness throughout the
inside of the launder. This means the entire launder is
lined with abrasion resistant polyurethane.
“There is therefore no need for additional liners to be
fitted inside the launders,” Young says. Another advantage,
this time for existing plants, is that the Multotec product
collection launder can be retrofitted to replace other
similar launder systems where wear is an issue.
Engineered for long life, the Multotec polypropylene
launders are designed to suit small diameter spiral banks of
2, 4, 6 and 8. The launders are engineered to allow optimum
flexibility in application and can be manufactured to
accommodate various bank sizes for both Multotec and third
party spirals.
Ease of installation facilitates a faster process when the
product collection launder is fitted. This is enhanced by
the lightweight construction as product collection systems
made from steel require extensive rigging for installation.
The launders’ non corrosive properties are significant
especially where the product collection launder is being
used in applications subjected to high levels of humidity
and excessive moisture which could cause corrosion.
“We initially focused the new launders on the minerals sands
and heavy minerals sectors of the market but ongoing
research and development work will ultimately see this range
expanded to the larger diameter spirals,” Young says. “In
addition, by undertaking all the manufacturing work in-house
at our quality controlled ISO 9001:2001 facilities, we are
able to facilitate faster lead times to the market.”
The new launder product has been field tested and units are
now successfully operating in installations both on Multotec
and other branded spirals. “The feedback we have received
from customers is that they are achieving superior wear life
on their spiral installations with the new launders,” Young
says.
Young says that Multotec is known for its extensive and
ongoing research and development ethic, as well as its major
investment in this area. “This has seen a number of
innovations brought to the industry resulting in cost
savings and more efficient processes, with enhanced
throughput and better yields being achieved. Close
interaction with our customers enables us to identify areas
in which we are able to assist by providing appropriate cost
effective solutions,” Young concludes. |
