Pebble, a kind of natural stone, is mainly from the pebble mountain which is raised from ancient riverbed because of the earth’s crust movement millions of years ago. The formation of pebble undergoes continuous extrusion and friction of flood and running water. Pebble is usually smooth under action of wave and flowing water and buried under the earth surface with sand.
The main component of pebble is silicon dioxide. It is rigid and smooth. It is compression-, wear- and erosion-resistant as a kind of ideal green building materials. As for its crushing technology, very often, the jaw crusher would be used at the first stage of crushing and cone crusher would be used at the second or third stage.
