    • ITM 627533,820345
    • old style H2761520359
  • 54°7'53"N; 7°34'38"W
  • Townland: Gortawee, Ballyconnell, County Cavan

Clinker manufacture operational: 4/2000 to date

Approximate clinker production to 2015: 13.7 million tonnes (32nd)

Raw materials: Carboniferous Limestone (Dartry Limestone Formation: 338-345 Ma) and shale (Meenymore Formation: 329-336 Ma) from the same quarries as used by Derrylin at 627200, 821300, Mucklagh townland, County Cavan, only 0.75 km from the plant.

Ownership: Quinn Group. Quinn Group was reconstituted as the Aventas Group in November 2013, and was acquired by Quinn Industrial Holdings Ltd in December 2014.

Also called Scotchtown works. Supplementing Derrylin, it was built just south of the border on the opposite side of the quarry, and only 1.3 km from the older plant. The Ballyconnell and Derrylin plants are exceptionally remote . Ballyconnell was served by a railway as recently as 1959, but now the only way out of the area is through minor country roads.

Ballyconnell cement kiln
Picture: ©2010 Deadstar, and licensed for reuse under this Creative Commons Licence. This shows the kiln section from the hillside to the northwest. Partially showing on the far right is the circular raw material pre-homogenisation store. An inclined conveyor feeds raw material to the ATOX rawmill in the green-clad building to the left. The tall cylindrical structure behind the rawmill, with a dog-leg duct on top, is the conditioning tower used to cool the kiln exhaust gases when the rawmill is not running. Immediately to the right of the rawmill is the kiln feed blending and storage silo, and behind that the 5-stage preheater tower. The two-support rotary kiln is in the centre. Just to the right of this is the fuel mill building. A duct brings hot, low-oxygen, high-CO2 gases from the preheater to act as an inert medium in which to dry and grind the fuel. The cooler is obscured behind the fuel mill building, but the sloping tertiary air duct can be seen above the kiln. Behind the fuel mill is the conical clinker store. Behind that, to the right is the rectangular finish mill building, and cement silos to the left.
