  • BG Europa project goes smoothly for Minffordd Quarry.

2nd May 2008 -  

BG Europa has recently been involved in a project to supply a new asphalt screen for a Barber Greene batch tower at Minffordd Quarry.

Owned and operated by Tarmac Western, Minffordd Quarry is located near Penrhyn, North Wales. A granite quarry opened for setts in the 1870s, following the opening of the Aberystwyth and Welsh Coast line; today Minffordd is now operated on a significant scale incorporating a crushing and screening plant with a coating plant playing a significant part of the daily operations.

The 2 ton - 80 tph Barber Greene batch tower currently operating at Minffordd was previously supplied by BG Europa. Having being originally installed at Tarmac Western Dolyhir, the plant was subsequently moved to its present location.

As principal contractor for the project BG Europa supplied a new Finedoor 4m x 1.4m - five full and one half deck vibrating screen. Constructed of 10mm thick rigid side plates complete with heavy duty bolted in decks the new asphalt screen incorporates greased bearing lubrication. High tensile woven wire mesh panels were fitted with apertures as specified.

BG Europa also supplied a replacement screen base frame complete with seal rubbers to suit the new screen and existing hot stone bins. The screen spring supports and an 18.5Kw electric motor drive are all located on this frame. Screen dust housing was also supplied which incorporated bolt-on panels and discharge hood with folding division plates to allow access to screen meshes.

Several ancillary items were also supplied including additional ducting, a section of hot stone elevator complete with chain and buckets and a wear plate lined discharge chute, which was installed between the hot elevator and screen. A stairway extension with handrails to modify existing access to the hot elevator head completed the specification

The new screen was fitted onto a new base frame supplied and enclosed within the dust housing at the BG Europa - Ashbourne workshop. This allowed the entire new screen section to be lifted into the Barber Greene batch tower in one operation. Installation was completed on Good Friday with the removal of the tower roof, with the new screen lifted into position on Bank Holiday Monday resulting in full plant operation by the Wednesday.

Malcolm Ellis, Quarry Manager, commented, "A very professional and extremely well executed operation carried out safely and to a high standard."
