Tullyraine Quarries extracts on average 300,000 Tonnes of aggregates per annum.

After blasting, usually once a fortnight some 15,000 tonnes of aggregate are brought down unto the quarry floor. After blasting from the quarry face our Parker 1100 x 650 primary crusher is moved in to commence crushing operations.

This material is reduced down to approximately 200mm – 100mm rubble; with associated grissley. It is then transported in dump trucks to either our top fixed crushing plant or our bottom mobile crushing plant.

There are a further 3 secondary crushers the first 2 reduce the aggregate down in stages, the final crusher produce the final size and shape of the range of material, which is 20mm, 14mm, 10mm, 6mm and Dust.

At this stage all these materials are a mixture and so are sent to the screen house which sorts the material into its various sizes by a process of passing or rejection over screens. The material now sorted according to size is then stored in bins under the screens. Doors under the bins allow loading onto lorries for dispatch or into a dumper, which will tip the material onto stockpiles on the quarry floor for future use.

This plant has a 36 x 10 Goodwin portable jaw crusher and a Goodwin Barsby double deck screen unit. It produces blinding plus 63mm and clean 60mm
