A London-based builders’ merchant wholesaler has moved into manufacturing with a Terex Finlay 674 screener producing single-sized aggregate from sea-dredged material.
Gill Aggregates has taken delivery of the screener at its Dagenham plant to process ballast into products for sale across London and the south-east.
The machine, supplied by Finlay Plant SE, is producing four sizes of material: 6mm sand, 6-10mm stone, 10-20mm stone and a 20mm-plus reject stone.
The 674 is a compact, easily transportable machine that offers rapid set-up and tear-down times. It has three decks giving a large screening area of 170sq ft to provide efficient processing even at small fractions and high capacity.
It includes quick wedge tensioning, access holes and a bottom deck hydraulic tensioning system to reduce time required for mesh changes.
All four discharge conveyors are adjustable and hydraulically fold for transport, with the fourth product ‘oversize plus’ conveyor featuring variable tilt and side slew to accurately discharge material for recirculation and stockpiling.
It is currently powering through 120 tonnes of material an hour at Gill Aggregates, with the processed sand and stone then packaged on-site or stored in bays at the facility.
Sukh Gill, depot manager, said: “The machine can take 10 tonnes of ballast in its hopper at a time, which it powers through to produce a great, clean product. It is proving economical because we previously had to buy the materials, but now we are able to take unprocessed material and make it into a saleable product ourselves.
“The plant also supports the orderly nature of the site, with its ease of access enabling us to get all around to keep everything running smoothly and free of build-up.”
