A four component sand and gravel processing system supplied by APS, the
specialist washing arm of the Finlay Group, is gearing up to relocate from its
present location at Tarmac Milfield to a brand new Tarmac site in Northumberland.
For almost three months, the mobile system, comprising a Terex Finlay 390 feed
conveyor, APS 300 high capacity triple deck sand and gravel Screening unit,
Finlay 200 Hydrasander and Trio 4432 twin fine material washer - all supplied by
APS - has been in position at Tarmac Milfield's Quarry.
Now, as Tarmac prepares to cease production at Milfield after almost 40 years
and commence extensive restoration works, the APS system is being relocated to
its new quarry at nearby Lanton.
Milfield has provided sand and gravel for an area stretching down to
Newcastle-upon-Tyne and Teeside, up to Edinburgh.
The APS system complements Tarmac's strong sustainability credentials at the
site, located in the Cheviot Hills.
Its low profile, compact aspect creates minimal visual impact and the unit is
engineered to reduce sound, in an area where the early phases of restoration
have already been recognised as outstanding, attracting a rich wildlife
including teals, swans and hundreds of mallards.
The site won an ‘Excellence in Restoration' award in 2003 from the Quarry
Products Association in recognition of its work.
Charlie Nairn, a director of Finlay Group, says: "The system has worked well at
Milfield. Since its introduction, production has increased by more than double
and the unit produces 300 tph, working to produce four different product sizes.
"The oversize material is fed via a transfer conveyor to a jaw crusher and
reintroduced back into the plant.
"For the move to Lanton, two of the major components can be fully road towed by
articulated vehicles and two others taken by low loader, so the relocation is
easy and uses minimal resources.
"In the past, as a company, our main focus has been inclined decks. However,
technology has moved on and flat decks now allow more control and greater
variable vibration for higher production tonnages - and more accurate screening.
"Ireland has really embraced the change to flat screens. England and Wales are
now catching up. Projects such as Milfield demonstrate their ability to deliver
high levels of efficiency and productivity, in tune with the surrounding
Dave Phillips, site manager at Tarmac Milfield, says: "The APS unit has been
very effective. Productivity has been increased, noise reduced and the system is
simple and easy to use. Importantly, the entire system is not obtrusive to the
