North Lincs Aggregates Ltd invest in more efficiency supplied by DUO.

Located at Sandtoft, Doncaster, North Lincs Aggregates Ltd (NLAL) is a family run independent business that owns and operates three quarries in the area. The Finningley operation has been established for 12 months and operates a Terex Washing Systems (TWS) M1700 Wash Plant. Operating at 160tph the plant produces a 0-4 grit sand, a 20mm and 10mm aggregate and oversize which is sold to the local concrete plants and satisfies the demand in the local market.

The Terex® M 1700 wash plant is a mid-sized mobile washing plant complete with on board hydraulically folding side conveyors for up to 5-way splitting of material in applications such as coal, crushed stone, recycled materials, iron ore, sand and gravel.

The M 1700 wash plant at Finningley works independently and is part of the range of innovative washing solutions from the TWS portfolio, and was supplied by DUO (Europe) Plc who are the English and Welsh dealer for TWS.

Originally moved in from their quarry at Cove the processing operation has produced an increasing amount of oversize and a decision was made to invest in a Powerscreen ® 1000 Maxtrak Cone Crusher, a Powerscreen ® Warrior 1400 and a tracked DUO Conveyor which has also been supplied by DUO (Europe) Plc.

Richard Mills – MD of NLAL takes up the story, “We have had a longstanding relationship with DUO who supplied the M1700 and other equipment for our other operations and it made sense to buy a 1000 Maxtrak cone to crush the oversize and a Warrior to dry screen the sand.”

The quarry which has reserves of approximately 3 1/2 – 4 million tonnes of Quartz gravel and sand is the last of the old Trent Valley seam and was originally an old former quarry which had laid dormant until purchased by NLAL 12 months ago.

Richard, commented, “We are a self-funding company and purchasing Powerscreen® equipment off a trusted supplier like DUO makes sense. We purchased the equipment outright as the brand retains a good residual value for when we need to upgrade again.”

The company currently operates 20-25 vehicles and has just acquired their third operation which is a clay quarry. Completing their current portfolio is a silica sand quarry at Cove which has very large reserves of 4 million tonnes. At this location, a DUO supplied Screener is at work processing top soil.

The processing operation at Finningley is relatively simple. Sand and gravel dug from the quarry floor is sent to the M1700 wash plant with the oversize stockpiled. This is then delivered by wheeled loader to the Maxtrak 1000 cone crusher. Operating at 100tph the material is crushed down to 20mm and an associated dust which is then stockpiled and then refed back through the wash plant with the raw material to bulk the feed material up.

Richard, further commented, “We have had both machines delivered in the last 3 months along with the tracked conveyor and it is great kit. The Warrior duties are to dry screen sand and gravel through a 4mm piano wire mesh and provide us with a dry building sand. Overall we are very happy with the equipment supplied by DUO and have every confidence in the reliability of the equipment and the service back-up.”

Nico Stroh – Development Manager at DUO, commented, “Powerscreen ® has a rich heritage of design and manufacturing excellence, and has grown to become a leading force in the original equipment manufacturing (OEM) sector. Powerscreen® machines cover the full range of material processing requirements in terms of mining equipment, quarrying equipment and crushing and screening machines for the mining, quarrying, demolition and recycling industries. The machines supplied to NLAL are perfect for their operation and offer reliability and efficient processing. We are very confident in our supply of the full range of Powerscreen ® equipment which blends perfectly with the TWS range of world beating washing equipment.”
