Case Studies & Resources

Locations

Killough Production Facility

The quarry is centrally located adjacent to the Cork-Dublin Motorway (M8), it encompasses a large portion of Killough Hill which is a very high purity limestone escarpment surrounded by agricultural land in Co. Tipperary.

Material for dolomitic products is sourced from the Roadstone mine in Bennettsbridge, Co. Kilkenny.

Construction on the new Killough Mineral Plant was completed in February 2020.  At the heart of the plant is a Bradley BM14 mill. This mill is capable of manufacturing Virgin Filler at a rate of 15-18 TPH and Animal Feed of 17-20 TPH. When manufacturing Fertiliser Grits this can be increased to 25 TPH.

The state of the art control system, with the Xoptix Intellisizer providing real time information on Particle Size Distribution, allows for maximum flexibility of production with an emphasis on reducing energy consumption.

The material is dried by a two stage fully modulating burner, this two stage burner helps to minimise LPG consumption thus reducing the carbon footprint of the plant.
