screens and classifiers (for the production of manufactured sand). Some stone crushing plants produce manufactured sand. This is a small-sized rock product with a maximum size of 0.50 centimeters (3/16 th inch). Crushed stone from the tertiary sizing screen is sized in a vibrating inclined screen (fines screen) with relatively small mesh sizes.

The products can be extracted immediately after the gyratory crusher as 0-32 mm or 0-63 mm fractions, if necessary; these materials are used when stability is needed for the given construction application. The tertiary stage produces fractions in sizes ranging from 0-2 mm to 16-32 mm. These products are used in asphalt and concrete.

In the process of granite crushing, two or more types of crushers are applied, so the combination of crushers is of great importance. A good granite rock crushing line ensures a smooth production, less …
