Aggregate Crushing Operation

Aggregate crushing can be processed in three stages according to final products applications: primary crushing, secondary crushing and tertiary crushing. The stone materials from quarry extraction will be fed into primary jaw crusher for initial size reduction. The output of the primary crusher is fed to a secondary crusher. Tertiary crushing is usually performed using cone crushers or other types of impactor crushers. Oversize material from the top deck of the sizing screen is fed to the tertiary crusher.

Between each crushing stage, there will be a feeding hopper and screening machine, the material is transported to fixed or vibrating scalping screens by gravity, belt conveyors, hydraulic pump, or bucket elevators. The scalping screens separate the oversize material from the smaller, marketable sizes.
