Understanding the most common rock types used in crushed stone production is essential for selecting the proper crushing process and rock crushing equipment. Here are some of the most common types: Granite: With a Mohs hardness of around 6 to 7, granite is one of the most common rock types used in crushed stone production.

Crushing is the process of size reduction of ore. Size reduction process begins with usage of explosives at the area for production of ore. In later stages, the size reduction process performed with crushers before grinding in mills is called "crushing". Although there is no limit set, the downsizing process over 3 mm is considered as "crushing

· The crushed rock should be clean (with limits on clay or other weak rocks, silt, and dust) and not contain deleterious impurities (e.g., mudstone, pyrite, coal, mica) that would reduce strength and durability.

· The study found that plots with crushed rock stored 0.15 tons more carbon dioxide per hectare when compared with untreated soils. If this process could take place in all California cropland, the researchers point out, it would result in carbon removal that could offset the annual emissions of 350 thousand cars.
