SCREENING AND WASHING
From a structural standpoint, they are
fabricated with A572 Gr 50 plate (45% higher
yield strength than traditional A36 plating) for
maximum strength. Side plates are a fully bolted
construction, which reduces and eliminates
cracking due to stress caused by welding. The
bolted construction also makes it easier to
change out worn components without cutting.
Bronze sleeves are integrated on both ends of
the shaft for protection in instances where the
outer race of the bearing could potentially turn
on the shaft. This reduces unnecessary downtime
and only requires the sleeve to be replaced. All
components slide onto the shaft, allowing for
easy removal and installation. The straight shaft
features jacking bolts in the mechanism tube that
support the shaft during change outs, eliminating
the need for a crane and thus improving safety
while minimising downtime. Screens are also
equipped with a quick change spring kit that
allows for the removal of the spring pack with
only minimal vertical clearance and no need for
an overhead crane.
The company told IM: “Operators looking to
upgrade their screening operations can have a
solution that fits directly into their operation with
no rework to existing structures. McLanahan’s
MAX Series Vibrating Screens make it easy to get
more from your screen without needing to
change your entire operation. Customers can be
sure they are getting a solution that will give
them more uptime, easier maintenance and a
safer working environment.”
demand for increasingly consistent sand
gradings. Given the increased requirement for
sand and coarse aggregates for our downstream
products, the time has come to grow our
production capability. As a result, we needed to
upgrade in order to ensure that we achieve
maximum tonnes per hour every hour and that
our plant is capable of adapting to challenges
such as variable deposit moisture content
brought by weather and natural variations within
the deposit. We have nurtured a solid
relationship of trust with CDE over the years and
had no hesitation in turning to them for an
upgrade of our existing CDE equipment. CDE
equipment is used across most of Roadstone’s
sand and gravel sites in Ireland and we have had
the opportunity to witness the reliability and
hard-wearing of the CDE offer.”
Kevin Vallelly, Head of Product Development
at CDE commented on Roadstone’s new Infinity
screen with VibroCentric electric drive system:
“A key success of the VibroCentric drive system
is the harnessing of the power used and
ensuring the maximum transfer of energy to the
material being screened. This system is
employed on the Infinity P-Line range of inclined
sizing screens. A unique shaft design allows for
a significant reduction in the weight of the drive
system and the screen assembly which results in
a significant reduction in overall power
consumption. As a result, dewatering
performance is maximised to allow the final

CDE Infinity screening
High tech screening technology CDE says is
becoming a must for washing plant operators
who want optimal production results from a
reliable range of equipment. “CDE invests
extensively in its research and development
department to remain ahead of the innovation
curve, and with all products being manufactured
and tested at its assembly facilities in
Cookstown, Northern Ireland, reliability is
guaranteed. A case in point, the Infinity screening
range was launched in 2016 and has since
become one of the firm’s most popular
products.”
The Infinity screens’ bolted construction
eliminates the need for welds and the U-Span
cross-members, in combination with the
construction of the side walls, deliver higher
specific stiffness that prolongs the working life of
the screen. Cathal Lavin, Location Manager at the
Roadstone Classis quarry, a subsidiary of global
company CRH Group, recently opted for the CDE
inclined sizing Infinity screen with VibroCentric
electric drive system. He explained: “Our existing
multi-sand plant and dry screen have performed
extremely well over their 15-year lifetime, but as
construction technology evolves, so does
