· Secondary crushing, as you can imagine, is the second stage of material processing following its initial reduction. At this stage, material will flow through perhaps a second impactor or even a cone crusher, which is effective at breaking down these types of material. There are also tertiary and even quaternary stages of crushing that exist to

During the screening process, these materials are separated into grades based on their particle size. In some instances, screening plants are used to separate materials immediately following the primary crushing phase, while other applications use screening equipment later in the process, right before materials are stockpiled for transport.

· Crushed stone often has an angular and jagged edge because of the crushing process. Gravel, on the other hand, typically has a very smooth texture and surface because of the natural weathering and wear of being exposed to running water. Unlike crushed stone, gravel is usually sold and used in its natural state.
