As some of you know, I work as an electrician in a granite quarry which produces 5 million tons a year. There are two quarry holes, this is the forked out one which is now being filled with clay overburden from the other hole.
This is a Catterpillar 988 shovel which can scoop up 10 tons at a go. Nathan, another electrician gives you an idea of scale.
This picture shows the "surge pile" where pre crushed rock piles up before going through underground feeders to the secondary crushing plant. The primary route from hole to surge pile can cope with up to 2500 tons per hour.
Everything is on a massive scale. The building in the background is a covered store and has underground feeders and conveyors taking stone to our rail loading plant, bitumen coating plants or to a wash plant.
This is one of two bitumen coating plants and can continuously produce 300 tons per hour of tarmac. At present we are suppling product for the M69 resurfacing project.
