Paterson's Construction & Demolition Aggregates Recycling Plant

DUNGANNON, NORTHERN IRELAND, 24th APRIL 2013 - Terex Washing Systems (TWS) have just completed commissioning a 150TPH Recycling Wash Plant in Glasgow in association with their Scottish dealer Blue Machinery (Scotland) Ltd. The plant which is now up and running, 10 Hours + per day, was installed for the well know independent quarrying company Paterson’s Quarries Ltd. The new site is located at their Greenoakhill Quarry & Recycling Centre, Glasgow.


Austin Carey, Managing Director, Blue Machinery (Scotland ) Ltd commented “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 recovery 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.” 


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 McPhillips, 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 option was sure to be the perfect solution. Based on these findings TWS proposed a bespoke system which is now ensuring that the construction and demolition waste material is being effectively processed and is producing saleable 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 at first hand the quality of clean aggregate and sand being produced.”



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) Ltd and Paterson’s and vigorous analysis on the feed product, Terex Washing Systems proposed their range of cyclone separators and utilized a prewash to manage this high level of silt (less than 63 micron material). Sean Loughran, Director of TWS commented “Blue Machinery (Scotland) Ltd have 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 (Scotland) Ltd 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 achieved from initial conception through to the production of high quality products.  Both Blue Machinery (Scotland) Ltd and TWS carefully considered the customer’s specific needs and manufactured a truly efficient plant which is now producing 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 Terex Washing Systems plant completes the recycling process with construction, demolition and excavated material taken from sites around Glasgow, 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.


Commenting on the new wash plant, Director Tom Paterson’s added, “As a major supplier of construction materials into the central belt the new Aggregates Recycling Plant is an important investment for our company to ensure we are able to offer a sustainable source of high quality coarse and fine aggregate. Our location is ideally suited to minimise haulage to and from the market we serve, whether this is for the excavations coming off site or for supply of material back to site. The aggregates plant gives our site a new lease of life and will ensure a long term supply of high quality material for our customers and for our own complementary business of Readymix Concrete and Concrete Blocks”


This is one of many plants TWS have installed where they continue to provide a unique solution for the customer’s individual 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 realized through their global dealer network, in this instance Blue Machinery (Scotland) Ltd.
