Crushing and screening plants are used for crush and seperate the stones to the desired dimensions. These plants are used to produce aggregate to be used in constructions, highways, railways, asphalt and concrete plants. Stationary crushing plants are used for continuous and long-time projects, mobile crushing and screening plants are used for smaller and short-term projects.

Crushing and Screening process generally consists of 4 steps.


1- Coarse Crushing Process After the material to be crushed is unloaded by truck, it is homogeneously loaded into the primary crushers/jaw crushers by the feeder. These equipments crushes the largest stones to one size smaller. The crushed material is transported to other crushers by conveyor belts.
2- Medium and Fine Size Crushing Process After the firts crushing process materials goes through a screen and then they are transported to the secondary crusher, jaw crusher with a belt conveyor for crushing. After that the crushed stones are sent to the screen again to bring the materials of various sizes.
3- Smallest Stone/Sand Making The crushed stone is sent to a cone crusher, vertical shaft crusher or impact crusher (sand making machine) for further crushing and shaping and is reduced to its smallest size.
Step 4: Washing If clean aggregate is desired, it is sent to the sand screws and the washing process is carried out.
