The Thomas Armstrong Group has taken delivery of its 25th
A new Terex Finlay 390 Hydrascreen is the latest addition to the fleet, which is being used by the group to process sand at its Overby Quarry site in Wigton, Cumbria, county Cumbria, England, one of the two sand quarries the company operates in the north-west.
In a partnership spanning 35 years, the group has worked closely with Finlay Plant Northern, part of the Finlay Group of companies, to introduce plant on site geared up to their exact needs.
“The machines we’ve had from Finlay Plant Northern are great, some of them now are over 15 years old and they’re still in operation, seven days a week, ten hours-a-day,” says Martyn Cueto, the roup’s quarry manager.
“And the new Terex Finlay 390 Hydrascreen is no exception to that. It’s cost effective to run, boasts a simple process and can work in confined spaces.
“The back-up and service is also fantastic with parts we need being delivered the next day.”
With “an extremely fuel efficient diesel-hydraulic system,” the 390 has a large capacity loading hopper and a remote-controlled tipping reject grid.
Featuring a robust 12’x5’ screen box on every deck, it is processing 110tonnes of sand from the quarry/hour, producing two different products.
The first, an oversize product, is fed to a washing plant to create a single sized aggregate and the second is a 3mm top-quality natural plastering sand.
The sand and aggregates produced at the Overby Quarry are sold to builders’ merchants across the north of the country.
“Thomas Armstrong’s don’t require a three-way split for this application so the Terex Finlay 390 Hydrascreen is the perfect solution for them,” says Charlie Nairn, managing director of Finlay Plant Northern.
“The screen box can be set at variable amplitudes and screen angles, meaning it has the capability to process sand to an accurate size, ideal for what it’s required to do at the Overby Quarry.”
