Crushing can be done in three or four stages, primary crushing, secondary crushing, tertiary crushing and, in some quarries, a quaternary crushing.Crushed rock, or product, is transported along the process line on conveyor belts or down chutes.

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.

Other types of crushing machine involved includes impact crusher, hammer crusher, gyratory crusher, VSI crusher, cone crusher and mobile crusher etc.

Quarry Grinding Mill

Grinding is the final stage in the comminution process and requires the most energy of all the mineral processing stages. Because of this, the tendency is to first blast (in the mine) or crush the ore as fine as possible to reduce the amount of larger materials sent to grinding, thereby reducing the overall energy consumption in grinding and, hence, comminution. If possible,grinding is performed wet as this requires less energy, allowing energy savings of up to 30 % compared to dry grinding.

Popular grinding mills applied in the quarry processing operation mainly include ball mill, high pressure mill, raymond mill, vertical mill, ultrafine mill and trapezium mill etc.
