The Complete Guide to Crushed Stone and Gravel

There are many types of crushers, but their main job is the same: Crush larger rocks into smaller pieces to be used for construction material. Crushed stone is then passed through different screeners to be organized and stored in different piles according to their size. The screening process starts by removing larger stones, then medium stones, and eventually goes all the way down to the stone dust.
