Audits
Overland
Conveyor is one of the leading providers of belt conveyor
design audits in the world. But why are
design audits important?
Complexity
of Design...
In
a recent survey of product designers and engineers,
42% identified design and product complexity as the
most important issue they face, well ahead of time-to-market
pressures (13%), competitive pressure (12%), and cost
reduction (11%).
Driven
by market demand, manufacturers are continuously working
to improve their products, delivering more features,
innovations and elements to set themselves apart from
the crowd. This usually means incorporating new technology
and more automation.
Customers
are also continually seeking increased throughput, more
control options, and greater automation. Manufacturers
must offer an increasing range of product variants and
specifications and more frequent release of new products,
or be willing to customize their products in order to
maintain a leading position in the market. Component
suppliers must maintain a larger catalog and respond
more quickly to new applications with new variants and
new material specifications.
All
of this leads to increasing complexity, and the trend
will not be changing any time soon. Most managers, having
conceded that complexity will continue to increase,
have turned towards technology to come up with ways
to handle it better.
Need
for Reliabilibity...
Belt
conveyors play an important role in the transportation
of coal. They are used extensively during mining, processing,
storage, transportation and, finally, in the generation
of power. Because a conveyor delivers a very small amount
of material over long periods of time, it is essential
they operate efficiently with maximum availability and
minimum downtime. Unlike a truck or train that delivers
large loads intermittently, a conveyor must deliver
a small, steady stream of material continually.
However,
reliability and availability are much more difficult
things to quantify or even define as there are so many
factors to consider when determining the appropriate
goal. And because belt conveyors usually operate in
a series, with transfers from one to another, downtime
on one conveyor will mean total conveyance system downtime.
For example, in a plant with 5 conveyors in series,
availability of 98% on each conveyor (that might be
considered acceptable) yields a system availability
of 90% (that would probably be considered unacceptable).
Therefore, belt conveyors need to be designed for very
high availability. Although classical design methods
have historically been considered adequate, it can be
argued they are not adequate to meet the availability
needs of current market requirements.
