for a targeted 1.5 million tonnes/year and equipped with
4 MW of installed power.
But in other applications, where a contractor or quarry
operator needs flexibility, mobile machines can be the
answer.
This is illustrated by the 100
th
Warrior 2400 mobile
screen manufactured by Terex’s Powerscreen subsidiary,
which was delivered to Galfar Engineering SAOG
in Oman. The contractor had originally asked local
distributor General Engineering Services (Genserv)
about a scalping machine, but with outputs of
700 to 900 tonnes per hour required, along with
the need for mobility, the recommendation came
back for the Warrior 2400.
The initial order for two machines has since
grown to six, including the 100
th
machine to roll off
the production line. All six are currently working on the
45 km Phase 1 of the Al Batinah Expressway project, where
high quality sub-base is being produced from feed material of a
nearby wadi (river bed).
A spokesman for Galfar said, “We are very happy with the
performance of our plant - each machine is working for up to
20 hours per day and producing high volumes of material. We
find that the machines offer a low operating cost per tonne and
we know that we can count on high speed local support from
Genserv when we need it.”
The Warrior 2400 screens are configured with a 150 mm punch
plate on the top deck and with a 63 mm aperture mesh on the
bottom deck, giving three end products. The -63 mm fines
are used for base rock on road projects. The mid-size material
(63 to 150 mm) is crushed with Terex cone and impact
crushers to produce smaller products for re-screening, while the
+150 mm material is processed with a variety of jaw, cone and
vertical shaft impact crushers to produce other aggregate fractions
as well as sand.
Oman-based Galfar Engineering SAOG is using a fleet of six
Warrior 2400 screens from Terex Powerscreen to produce
aggregates for road-building projects.
