Finlay Plant supplies screening technology for recycling JV

A Terex Finlay 694 Supertrak, supplied by Finlay Plant South East, is driving forward productivity at Scratchwood Depot, where a joint venture between Lafarge Aggregates and GRS Roadstone has been developed to recycle construction and utilities waste.

The 694 screen is reclaiming concrete, stone and masonry into five grades of recycled product at the site, which is located off the M1 on the outskirts of North London, where Essex-based demolition, crushing and recycling contractor Haigh is contracted by GRS Roadstone and Lafarge to crush and screen the material.

Haigh have invested in new machinery to deliver the contract, with the 694 screen central to the project’s operation. Currently, 240,000 tonnes of waste material a year are scheduled for reclamation at the site.

Once processed, the material leaving Scratchwood is used for a variety of construction-related products, including the manufacture of concrete that contains part-recycled materials, in line with the recent British Standard BS 8500.

The material leaves the 694 screen in sizes of 40mm, 40-25mm, 25-20mm, 20-10mm and -4mm. The screen’s double-deck vibrating grid head system scalps off the 40mm, which is then re-crushed, for maximum efficiency.

Jon Fisher, regional director of GRS Roadstone for London and the south-east, said: ‘By producing more single-size products, the material is much more marketable and, as a result, the 694 drives more value out of the waste goods.

‘The screening process is proving very accurate and the 694 offers a 20ft deck, providing a good deal of space to enable more material to get through. This machine was the best choice for us in terms of productivity and performance and it is backed up by Finlay Plant South East’s comprehensive on-site service and support programme.’

Leon Sheehy, managing director of Finlay Plant South East, worked with Haigh and Leicester-based GRS Roadstone to introduce the Terex Finlay 694 Supertrak on the site.

A number of options were specified under the purchase, including a Caterpillar engine. Mobility was also important and Haigh chose the 694 on tracks for on-site mobility and a separate, purpose-built bogey to allow the plant to be transported to other locations where necessary, without the need for a low loader.

Leon said: ‘The 694’s output increases the volume and value of the reclaimed material, creating sought-after products for the construction and utilities sectors from waste goods, which are being diverted from landfill.

‘The 694’s capability, combined with the options that have been configured to meet the individual needs at Scratchwood, have ensured this is transforming operations on the site.’
