Two PT R400 Mobile Jaw Crushers bought to crush foundations

ADM Regeneration based in Lymm, was formed in 2011 by current owner Adam Matthews, undertaking demolition, dismantling, decommissioning and earth works projects initially using hired equipment.

Due to constantly completing projects to the highest standard and consistently to pre-agreed timescales, the business grew quickly leading to the progressive step of purchasing their first piece of plant equipment, a used Powerscreen XR 400. The machine was 4 years old with 4,000 hours on the clock and ran virtually non-stop for a further 4 years and 8,000 hours due to the care the machine was receiving in the form of OEM parts and regular servicing from Blue Spares and Blue Central Engineers.

Over the years, the relationship between Blue and ADM stayed solid, so when ADM were awarded the contract by Peel Logistics to ‘prepare’ the former 45 acre Sonae
Chipboard Factory site in Knowsley, on Merseyside, Blue were firmly in the frame to provide the heavy machinery ADM anticipated they would require to do the job. Specifically the job involved the removal of all relic slabs, structures and foundations as well as filling in the voids left in a controlled manor to allow for cost effective foundation solutions to be achieved during future development of the site.

The company did look at various suppliers for the crushing equipment required for the job, but the robust build of Powerscreen equipment and the fact that their previous machines from the manufacturer had worked so well were both contributing factors for Adam choosing a New Premiertrak R400 Jaw Crusher. A further plus for this particular application was the machines’ ability to cope well with contaminants such as rebar, specifically the hydraulic release chamber, allowing the chamber to ‘dump’ and pass un-crushable material.

Commenting on the performance of the machine, Adam told us, “The PT400 was crushing circa 2,000 cubic metres of material per week and doing an exceptional job. And not only that, but the fuel consumption was averaging out at just 20 litres per hour, so the machine was proving to be highly efficient.

It wasn’t long into the contract before ADM decided to purchase a second identical machine due to ADM’s ever increasing workload, which included the award of several large contracts not to mention the volume of materials requiring crushing on Sonae. Over the 26 weeks of working on the site, ADM extracted and crushed approximately 20,000 cubic metres of tarmac and 50,000 cubic metres of concrete. The Premiertrak R400 was taking the material down to less than 125mm, however, due to the high quality of the crush, it is likely that the material will be further screened to create a high quality secondary aggregate of MOT Type 1 specification together with 45-75mm stone that will be used for the proposed foundations of vibro stone columns. As a consequence of the large volumes of crushed product generated, it will be possible to generate all of the MOT Type 1 and vibro stone for the redevelopment of the site, which aside from the significant financial saving it will afford the client, represents huge environmental benefits by minimising haulage to and from site and removing the need to mine valuable natural assets, an achievement that Peel Logistics, strongly supports.

Commenting on the project, Matt Fitton, Director of Development at Peel Logistics said, “We selected ADM Regeneration to help create a truly oven-ready land opportunity for build-to-suit options up to 800,000 sq ft at Knowsley Business Park. We are pleased that site works are now nearing completion thanks to a great job by Adam and his team.”
