Terex Pegson clear-up in the valleys

Celtic Crushing, the Aberdare-based crushing and screening contractors, are using four Terex Pegson mobile crushers in the final phase of a major site clearance and restoration project in Merthyr Tydfil, South Wales.

The contract involves the crushing of over 135,000 tonnes of concrete slabs broken out during demolition of the old Ebbw Vale steelworks. The decision in 2002 to close the steelworks left over 81ha of land adjacent to the town requiring preparation for future development.

Edmund Nuttall, the main contractors for the £9.5 million remediation contract, are overseeing a range of on-site processes, from contaminated land cleaning through to full site clearance and landscaping. A major criterion of the contract was that only a small fraction of material would go off site. The rest is being treated in situ using a mixture of bio-remediation, soil washing and crushing and screening.

Much of the area was covered with 600mm thick, heavily reinforced concrete slab, which, once broken down by impact hammers, is fed to the four Terex Pegson crushers currently operating at the site. The two Premiertrak 1100x650’s and two XR400 machines are set up to produce a –200mm product, which is being used on site as general fill material.

Celtic Crushing’s operations manager, Ben Sherratt, said: ‘Before we put these machines in, we tried two other types of competitors’ machines, which proved less able to keep up with production. When dealing with large amounts of rebar in the concrete, the machines have to clear it without blocking. With the Terex Pegson machines, good clearance is provided, so these problems are alleviated.’
