How Does a Rock Crusher Work? | Sciencing

A rock crusher is a device used to crush rocks into smaller pieces, usually for gravel or some other road or building application. Most rock crushers have a hopper at the top -- a container which holds the rock above the crusher and uses gravity to feed it in. Alternately, rock crushers can use a belt drive to continuously transport the rock into the crusher.
