Glossary of Terms
Aggregates – Stones, sand, gravel and other materials that are used in construction.
Berm/Bund – An earthen barrier, covered with native plants that provides a physical and visual screen between public property and a quarry site. Berms/Bunds also limit access to the site and help keep noise levels down in the community. Bunds can also be within a quarry (in this case they are made of aggregate.)
Buffer zone – An area surrounding a quarry that helps provide a visual and sound barrier between the quarry and the surrounding community. These buffers consist of naturally occurring plants and trees, planned habitats and other areas.
Closed loop water system – A system of capturing and recycling the water we use in the processing plant.
Conveyor belt – An endless, moving, flexible belt that takes stones from one place to another around the processing plant.
Crushers – The machines used to break big stones down into smaller stones. Stones go through several different size crushers during the processing operation.
Crushed stone – Stone that is crushed to a specific size in a quarry processing plant.
Dust suppression – The process of reducing the amount of dust that goes into the air.
Haul trucks – Trucks that haul loads of stones from the pit to the primary crusher at the processing plant. These can be dump trucks (often) or road trucks.
Permitting – The process of getting approval from local and regional council or government agencies to operate a quarry.
Pit – Another name for a quarry. A place where stones are dug or mined out of the earth.
Pit loader – An excavation tool that helps move the stones from the earth onto conveyor belts or into haul trucks.
Primary crusher – The first crusher that big stones are crushed by. The primary crusher makes the stones small enough to go through the secondary and tertiary crushers.
Processing plant – Where stones from the quarry are taken to be processed into different sizes.
Quarry – A place where stones are dug or mined out of the earth.
Quarrying – the process of digging stones out of the earth.
Screening – Different size screens (like a filter) are used in the processing plant to separate stones into piles of the same size. stones are passed through several different size screens during processing.
Sediment – Sand and other matter that is in the water that we recycle. Sediment is heavier than water and settles to the bottom of a recycling pond.
Stockpile – Large piles of stones and sand where trucks go to pick up loads of the processed construction materials.
Vibrations – Movement that may be caused by crushing.
Water quality regulations – Local council regulations that must be met if water is allowed to flow from a quarry site into a stream, river or to soak into the ground.
