Owned and operated by Bardon Aggregates (a subsidiary of Aggregate Industries) Hulands Quarry is situated 2km to the East of Bowes, near Barnard Castle in County Durham. Currently processing approximately 300,000 tonnes of limestone per annum, extraction dates from the 1850’s when the original quarry was developed in conjunction with the South Durham and Lancashire Railway which was opened in 1861. Subsequent supplies to the LNER led to further development of the site.

As part of regular maintenance on the crushing and screening plant it led the production team at Hulands to contact leading screen manufacturer Finedoor to supply a quick replacement to ensure continuity of production. Specialising in dimensionally similar replacement screens Finedoor can easily supply a screen that can be installed into an existing location, designed and manufactured to sit onto existing steelwork.

After a full site survey of the existing screen Finedoor manufactured and supplied a Ritescreen Triple Deck Aggregate Screen 4.3m long x 1.38m wide which would process the same product specification currently been fed by the existing screen with the same feed material.

Manufactured with 10mm thick rigid side plates with heavy duty bolted in deck frames and inclined to 18° the new screen was designed to suit side tensioned screen media of choice.

Fully tested before despatch the top and middle decks were fitted with a full set of HTWW screen media with apertures to fit product requirements and the bottom deck with one full set of Extraflex rubber tensioned screen media with 8mm FR apertures which was removed from the existing screen and refitted. Additionally, a dust encapsulation system was also supplied and installed in the Finedoor workshop to facilitate dust retention within the screen.

Installed by Bardon engineers within the stipulated timeframe, Finedoor assisted with commissioning of the screen after installation. Finedoor also undertook a vibration test of the existing structure.

The project was a complete success; Alan Connolly – Manager, commented, “The bespoke screen that the Finedoor Engineers supplied was a good investment and provided me with a product that totally achieved our specification. The screen was designed to fit our existing unit without any modification to base steelwork or chutes and was commissioned to a high standard with full support from Finedoor Engineers included within the contract.”
