Extracting the rock the process starts by breaking off large chunks of rock from the quarry walls, usually through controlled blasting this rock is then moved using loaders and trucks to a primary crusher the primary crusher the crusher reduces the overall size of the material to make it easier to process
Quarry, place where dimension stone or aggregate sand, gravel, crushed rock is mined the products of dimension stone quarries are prismatic blocks of rock such as marble, granite, limestone, sandstone, and slate after cutting and polishing, these materials are used in the primary construction
A quarry is a place where rocks, sand, or minerals are extracted from the surface of the earth a quarry is a type of mine called an openpit mine, because it is open to the earths surfaceAnother type of mine, a subsurface mine, consists of underground tunnels or shafts the most common purpose of quarries is to extract stone for building materials
If the rock is processed in mobile plants, excavators transfer the blasted rock to crushers which are usually located directly alongside the quarry wallThe crushed stone is then either transferred directly to the next processing stage on conveyor belts or removed by trucks
