RESTORATION OF FORMER GRAVEL QUARRY BLACKHALL, PUNCHESTOWN, CO. KILDARE
Most people consider it a blessing to wake up looking forward to going to work, this is certainly the case with Jason Griffith, site manager at Behan’s Land Restoration located in Kildare. Machinery mad since a young boy, he happily spends his days surrounded by a host of equipment to help manage this busy 92 acre land restoration site. He is particularly pleased with the latest additions to Behan’s machinery portfolio; a Terex Finlay J 960 Jaw Crusher and 863 tracked mobile heavy duty screener supplied by Ormonde Machinery.
Originally a sheep farm, owned and run by the Behan family, from the 1970’s the site was leased by Ready Mix to excavate the sand and gravel that lay under the farmland. In 2002 the quarry was in the main fully excavated and the family took on the business of restoring the former Blackhall quarry. So began Behan’s Land Restoration, taking in construction and demolition (C&D) waste for restoration, backfilling and recovery purposes.
Initially there was a reasonable amount of C&D waste available, however following the severe downtown in the construction industry from 2009 until 2015 there was a corresponding drop in material available for restoration and recycling.
The ability of Behan’s Land Restoration to invest in recycling was also hampered by the failure of the Irish State since 2011 to determine End of Waste status for recycled materials. However, a decision on this issue is understood to be due in 2017.
The availability of construction waste is growing. The Construction Federation of Ireland noted at its annual conference in October 2016 that construction and demolition waste is growing in the Dublin area and that capacity to deal with it is an ongoing issue.
The quantity of C&D waste in the whole of Ireland in 2013 was approximately 2.9 million tonnes, but, since then it has started to grow again and in recent years it is reaching some 5.1 million tonnes per annum. With a surge in house building and new major infrastructure projects such as the National Children’s Hospital, DIT Grangegorman, and Dublin Airport’s second run way to name a few, the volumes coming on track will only be increasing.
For Behan’s, it means a steady flow of waste coming to the site which needs to be managed according to the best environmental and landfill operational practices. With approximately 400,000 tonnes of waste per year to deal with, the company needs robust machines to create the various grades of stone required to most efficiently deal with backfilling the site. The company based its decision to invest in Terex Finlay on its past experience of working with the brand, having previously used a 393 Finlay which proved a great workhorse for them.
When asked what were the main motivations for selecting the J960 Jason remarked “We were looking for a jaw crusher that could pack a punch but which fitted with our budgets, the J960 has proven to be an aggressive crusher with high throughputs” “We are seeing throughput of approximately 130 – 140 tonnes per hour of minus 100 mm materials. This is then fed into the 863 screener, which with its versatility works well with the J960”
Fuel efficiency has proven to be a real positive for the company, with unexpectedly low running costs. “The telematics system indicated we are doing about 17 litres of diesel per hour, from both an economic and environmental perspective this is positive for us”
The compact size, excellent mobility and high crushing capacity even at tight settings in recycling and hard rock operations make the Finlay J-960 ideal for small to medium sized operators such as Behans.
Working with the Finlay J960 is the 863 heavy duty screener, Jason outlined why he selected this screener “The 863 was both compact and aggressive and most suitable to work with our processing of construction demolition and our recycling application” “Our machine is fitted with a 45 mm top deck and 20 mm bottom deck mesh, it splits the material off the crusher to give the specified products required. In our case 20mm to 45 mm for drainage, + 45 – 90 for roads and finally the fines which is treated as waste product.”
With such a busy site, avoiding operational downtime is a priority. When selecting a partner to work with, Behans were looking for a support team with the expertise and ability to respond quickly.
For Jason working on site with limited staff, having technical and sales support in the background is a massive source of reassurance. “With the recent weather conditions, we were receiving quite a bit of sticky material – we simply made a call and Ormonde’s service engineer came down, changed the mesh which significantly improved production off the first belt”
As with all Terex Finlay jaw crushers, it comes with the T-Link remote monitoring and fleet management telematics system installed. This system enables owners remotely manage and stay connected to; keep track of their equipment, monitor work progress, manage logistics, access critical machine information, optimise machine performance and perform remote operator support.
Ormonde Machinery supplies a wide range of materials processing solutions, it prides itself on having not only expert teams in house but as Ireland’s Terex Finlay dealer, access to a host of engineering expertise. The company has been dealing with a number of land restoration projects and Conal Mullan Managing Director recently commented that “We are delighted to be working with Behans, as well as other recycling operations across the country. Each project we work on, we learn something more and this feeds into a continual process of improvement for us as a company and the services we bring to our customers”
