• BG Europa complete dryer drum refurbishment for Tarmac Skipton Rock Quarry.

29th March 2011 - BG Europa (UK) Ltd (BGE) have recently completed the refurbishment of another dryer drum for Tarmac Limited this time at their Skipton Rock Limestone Quarry at Skipton, North Yorkshire.

Called to review the condition of the existing dryer drum BGE engineers discovered that the drum shell was still in good condition and with some refurbishment, would provide years of service. However, the flights, drum seals and trunnion rings were in obvious need of replacement. Ultrasound readings allowed BGE engineers to determine specific areas of wear, and using this information the flight design was remodelled and wear bands installed to protect the existing shell, maximising life expectancy.

The decision to remove the drum from site for refurbishment was taken as the safest and most efficient method as it also allowed the trunnion rollers to be easily replaced whilst the drum was in the BGE workshop.

The drum was removed from its building by BGE and transported to their workshop in Ashbourne where the necessary equipment and expertise required to undertake these works exists.

During refurbishment both trunnion rings were removed and replaced on new saddle arrangements. Once the dryer flights were removed they were replaced with a new efficient design which included insulation flights within the combustion zone. Where drum wear had been detected new internal wear bands were installed and the rotary elevator was also refitted to correct the issue of leakage. The project was completed with new drum end seal arrangements and insulation with 50mm glass fibre.

Refurbishment was undertaken over 5 days before the drum was returned within the allotted time frame for reinstallation. Once the drum was installed on the chassis and the building roof replaced, new neoprene seals were fitted to increase drying efficiency by reducing excess air entering the drum. The drum was also tracked during production before the site was left clean and tidy.

The refurbishment was a total success, Martin Dobson - Quarry Manager, commented, "The overall service provided by BG  Europa was extremely comprehensive and has helped us to reduce our energy costs. We would not hesitate in choosing them again for further installations."
