  • How a Rock Quarry Works

How a rock quarry works

Rock quarries usually operate for at least 30 years and are developed in distinct benches or steps. A controlled explosion is normally used to release the rock from the working face. It is then transported by truck or conveyor to a crusher, where it goes through a series of crushing and screening stages to produce a range of final sizes to suit customers’ needs.

Just enough explosive is used in blasting to break the rock from the face. A powerful excavator loads the rock into dump trucks for delivery to the primary crusher.
