crusher (crusher inlet size: 950mm) runs at around 22 litres
an hour. This is about a third of the fuel that machines
from other manufacturers use — nobody can touch our
fuel consumption. This is because all of our machines run
diesel-electric drives, and all the drives, except for the tracks,
are electrical and when the machine is in working mode,
everything — even the crusher, which is driven directly from
the engine via fluid coupling — is running off electricity,
ensuring exceptional fuel consumption.”

The large engine compartment facilitates maintenance, and other service
components are easily accessible via the all-round work platform.
Screening media are manufactured from a special wear-resistant
spring wire steel or round wire to withstand the workload and produce
consistently accurate results.

Lantie van der Merwe, sales consultant: Kleemann at
Wirtgen SA’s Mineral Technologies division, explained the
specifications and operation of the MS 703 EVO. Developed
and designed in Germany, and built at the Kleemann facility
in India under the same quality assurance systems enforced at
all Wirtgen Group facilities across the globe, the 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 150mm
up to four fractions.
A member of the company’s versatile and efficient
Mobiscreen MS EVO line, the MS 703 EVO is intended for
use in applications in both the mining and construction sectors,
with its favourable transport dimensions and short set-up times
designed to meet the demands of contractor crushers.
“The ‘MS’ stands for mobile screen, the ‘70’ refers to
the 7m 2 screening area (1.52m × 4.4m), and the ‘3’ refers
to the triple deck. The machine has a feed capacity of 350
tonnes per hour with a maximum feed size of 150mm, and
can readily accept feeding by means of a wheel loader or
excavator, or directly from a crushing plant. The feeding
height to the slotted grate is about 3.6m. The feed hopper
is available in two sizes, 8m 3 or 10m 3 , and can operate with
or without the folding grate,” said Van der Merwe. Available
with either a diesel-hydraulic or diesel-electric drive, the
MS 703 EVO’s dual power option allows for the use of
external power, with the 75kW Deutz engine using an
average of 10–12 litres per hour.
