Cobble processing contains three procedures, coarse crushing of jaw crusher, medium and fine crushing of impact or cone crusher, and shaping stages of sand making machine.
♦ The first stage: Coarse Crushing
The lump cobble will evenly go through the vibrating feeder and transport to jaw crusher for coarse crushing. After the separation by the vibrating feeder the crushed material then will be transported to the impact crusher or cone crusher by the belt conveyor for medium or fine crushing.
♦ The second stage: Medium and Fine Crushing
The medium or fine material crushed by impact crusher or cone crusher will be separated by vibrating screen. The material with bigger granularity will be re-sent to impact or cone crusher again.
♦ The third stage: Shaping
The crushed cobble will be sent to the sand-making machine for further crushing and re-shaping. If the clean cobble is needed, then it could be sent to the sand washing machine for cleaning.
