With a number of strategically located railheads and a network of processing plants located in London and the south-east, Day Aggregates processes construction & demolition waste for reuse in a variety of construction applications, provides a range of aggregates and now has a significant presence in the incinerator bottom ash (IBA) market in these strategic areas.
The company has purchased more Volvos for its recently commissioned IBA facility in Greenwich, south London.
A new Stage IV-compliant EC250E weighing in at 25 tonnes (pictured) has been put in charge of handling deposited IBA after it has settled during its three-week maturation process, while an L150H loading shovel complete with 4.4cu m bucket is rehandling the product once it has passed through the screening plant.
Stuart Holmes, plant manager, said: “We are well on target to bring in some 100,000 tonnes a year of IBA to Greenwich for processing. The EC250E has been equipped with our bespoke design for the application in a challenging environment.
“We’ve specified the short dipper arm to give maximum breakout force, an hydraulic hitch and a selection of buckets which can be interchanged to deal with the varying nature of the material.
“The machine itself has been coated in two-pack lacquer on the superstructure panels as well as the cooling package to prevent accelerated wear.
“The other major modification is in extending the superstructure chassis rails to allow an 800-litre water tank to be sandwiched between the counterweight and the engine compartment.
“This feeds a Dynaset HPW water suppression system, which has been piped down the length of the equipment and used as an additional means of providing dust suppression inside the shed.”
Processed material is handled by the L150H loading shovel, which is powered by a 13-litre, 300hp Volvo Stage IV engine.
A a maximum torque of 1317Nm is achieved at just 1,450rpm, and the resultant fuel savings are further enhanced by Volvo’s Eco pedal, which encourages the operator to run the machine at its optimum rpm in the engine’s torque curve.
It is equipped with a 4.4cu m rehandling bucket.
