·Secondary Crushing In mineral processing it is assumed for the present purpose that intermediate crushing is not necessary and that the run of mine or quarried mineral has in one pass been reduced in size so that all is below say 6 in ring size From this stage forward the utilization of the product assumes primary importance
·Primary crushing is for the robust The very first crushers invented were jaw crushers which are built to reduce the size of large materials and operate with high volume in primary crushing Their main purpose is to reduce the material to a small enough size that it can be transported to the next crushing stage by conveyors
2 ·Secondary crushing The rough crushed rock from the previous phase travels to a second crushing station for further size reduction This stage typically uses a cone crusher which also uses compression to break the rock down Tertiary crushing This phase focuses on turning the raw crushed rock into a marketable product Vertical shaft impact
A concrete plant also known as ready mix concrete plant is usually located inside the city and concrete is transported to the site by a concrete truck mixer Ready mixed concrete plants are required for the durability reliability safety and environmental protection of concrete plant systems In Precast Applications
3 ·smaller sizes Depending upon the feed and product particle size the crushing operation can be classified as follows 1 Primary crushing The feed material is usually the run of mine 2 Intermediate crushing or secondary crushing The feed material is usually product of a jaw crusher 3 Fine crushing or coarse grinding
