Terex Washing Systems (TWS) have just completed commissioning a
150 tph Recycling Wash Plant in Glasgow in association with their
Scottish dealer Blue Machinery (Scotland). The plant which is now
up and running, 10 hours per day, was installed for the well known
independent quarrying company Paterson’s Quarries. The new site is
located at their Greenoakhill Quarry & Recycling Centre, Glasgow.

“WE ARE DELIGHTED
to continue our close
working relationship with Paterson’s of
Greenoakhill in supplying this new TWS
washing plant for their new materials recov-
ery centre at Greenoakhill. We have worked
closely with the Paterson’s Group over
the last 10 years and look forward to a
continued working relationship with them,”
comments Austin Carey, managing director,
Blue Machinery (Scotland).
A bespoke Terex Washing System plant
is processing construction, demolition and
excavation waste to produce four grades of
stone and two grades of sand. Fergal McPhil-
lips, sales manager for TWS explains, “Upon
careful analysis of the feed material and
being mindful of the large variation in the
silt content, it was established that specific
attention was necessary when choosing the
sand plant. With this in mind a flexible sand
plant with a unique pre-wash optionwas sure
to be the perfect solution. Based on these
findings TWS proposed a bespoke system
which is now ensuring that the construc-
tion and demolition waste material is being
effectively processed and is producing sale-
able aggregates and sand.” Garry Stewart,
applications & sales support engineer, TWS
added, “The high silt content of Paterson’s
construction and demolition material was a
challenge which TWS relished. We knew we
had the expertise and technology to convert
this sticky clay bound material into saleable
building materials. The Paterson’s material
is hugely variable and it was critical that we
designed and manufactured a plant which
could handle these variations. On a recent
site visit we witnessed first hand the quality
of clean aggregate and sandbeingproduced.”
Paterson’s approached Blue Machinery
(Scotland) Ltd as they required a Recycling
Wash Plant to deal with tens of thousands
of tons of construction, demolition and
excavation waste. Extensive testing and
sieve analysis highlighted that the material
to be processed had a very high silt content
of 30% plus. After consultation with Blue
Machinery (Scotland) and Paterson’s and
vigorous analysis on the feed product, Terex
Washing Systems proposed their range of
cyclone separators and utilised a prewash
to manage this high level of silt (less than
63 micron material).
Sean Loughran, director of TWS com-
mented, “Blue Machinery (Scotland) has a
strong history in washplant sales in Scotland
with the previous Powerscreen Brand and
were the natural choice as the dealer for
TWS in this area. The Blue Machinery (Scot-
land) sales team is highly respected within
the Scottish market not only for high quality
products they sell but also for their high levels
of application and technical knowledge.
The Paterson’s Plant is a demonstration of
what can be achieved from initial conception
through to the production of high quality
products. Both Blue Machinery (Scotland)
andTWS carefully considered the customer’s
specific needs and manufactured a truly effi-
cient plant which is nowproducing the goods
in terms of high quality recycled aggregates.”
The end products are being sold into
the market for construction projects and
groundwork contracts throughout Glasgow
as well as being used in Paterson’s Readymix
and their concrete block making operations.
This TerexWashing Systems plant completes
the recycling process with construction, de-
molition and excavated material taken from
sites aroundGlasgow, which is processed and
is then returned to those sites in the form of
clean, sized aggregate for drainage, Readymix
Concrete, concrete blocks and asphalt.
This is one of many plants TWS have
installed where they continue to provide
a unique solution for the customer’s indi-
vidual needs, which is achieved through
years of expertise from rich heritage and
legacy companies. Post plant installation,
TWS is committed to providing outstanding
customer support which is realised through
their global dealer network.
