Rock Quarry Operation
A rock quarry is one type of mine not located underground. The quarry is usually in an area known to be abundant in particular rocks or formations of rocks. The terms "rock quarry" and "gravel pit" are often confused or used interchangeably.
Mining of most rocks is for use in construction projects. Rock quarries are located around the globe. A quarry usually has a heavy concentration of one particular type of rock like limestone, slate, granite or marble.
A rock mine is much easier to excavate than other types of mines. Rock mines begin as shallow pits and grow larger as the rock is withdrawn. These mines are mostly above ground level and are commonly about 60 feet deep. While quarries normally yield rocks, they also contain minerals.

Quarry Crushing Production Plant
The primary crusher is fed via a chute and vibrating feeder. Primary crushing is usually by a jaw crusher consisting of a heavy metal plate which moves backwards and forwards against a fixed plate. The output from the primary crusher is conveyed onto the primary stockpile from which the secondary crusher is fed.
Secondary, tertiary and quaternary crushers are generally gyratory, or cone crusher. Each stage of crushing produces progressively smaller sized stones. In order to produce a usable end-product, the crushed rock has to be screened into various size categories. Crushed and screened rock is called aggregate.
