Classifying screens
The Mobiscreen series from Kleemann
comes with classifying screens that are
renowned for their inherent flexibility,
which contributes to optimal functioning
and resultant output values. Suitable for
a host of applications, the MS 703 EVO’s
adaptability is made possible by the variety
of available screen casing sizes as well as
the ease and speed with which it can
be transported.
Screening media on a classifying screen
plant are put to the test on a daily basis and
are manufactured from a special wear-
resistant spring wire steel or round wire
to withstand the workload and to produce
consistently accurate results.
Double bracing at intersections makes
high mesh stability – and therefore uniform
screening – a possibility, which is also
influenced by grain shape, moisture content
as well as the loaded volume.
Various options
Square mesh screen surfaces are the most
commonly used and are predominantly
used in applications where a cubic shape
is required. Different wire qualities and
thicknesses are available: the thicker the
wire, the longer service life it will have; the
thinner the wire, the higher production it
will ensure. Rectangular mesh screen
surfaces are for screening cubic grain sizes
and are often used to sort natural gravel at
high throughput. The Harp screening media
are used for screening damp material and
difficult screening products.
They boast a self-cleaning mechanism
through the natural vibration of the
longitudinal wires and should be inserted
at the lower deck of the screen. The harp
screen surface is available in different
versions, including W-harp, S-harp, and
Varia harp.
With fast set-up time, operator-friendly
design and cost-saving features, the
Mobiscreen MS 703 EVO is backed not only
by Kleemann’s exacting standards, but by
fully qualified service technicians available
24 hours a day as well as all recommended
spares available at Wirtgen SA’s Pomona
offices. Launched in South Africa on 9
June 2017, the local market can expect
to learn more about this dynamic new
screening plant by means of road shows,
demonstrations and site visits co-ordinated
by Wirtgen SA.
Developed and designed in Germany,
the Kleemann MS 703 EVO is a triple
deck mobile classification screen that
precisely screens out almost all types of
coarse natural stone, residual construction
materials and iron particulates of up to
150 mm up to four fractions.
With applications in both the mining and
construction sectors, this screening plant
screens out material after the initial crushing
process and offers superior performance,
fuel efficiency and intuitive handling.
Measuring in at 1,520 m x 4,440 m with
a 75 kW engine and with a feed capacity of
350 t/h, the MS 703 EVO comes with either
diesel-hydraulic or diesel-electric drive. In
addition well as a large number of screening
media to achieve a variety of final grain
sizes and to take different feed material.
Thanks to a generously proportioned
screen casing, material is well-distributed
across the screen surface and its built-in
peripheral platform means the screening
plant is easily accessible for maintenance
and screen media changing.
The plant boasts a large feed hopper
which can readily accept feeding by means
of a wheel loader, an excavator or directly
from a crushing plant. Both folding and
vibration gates are optionally available.
The plant also has a special space-saving
transport position, so that the most compact
dimensions can be achieved should the
plant be required to move to a new site; this
is complemented by quick set-up times and
fast screen media change capability.
