Jaw crushers are the most common primary crushers used in the mining and construction industry. They are represented by a fixed jaw and a moving jaw that form a V-shaped crushing chamber. The moving jaw moves back and forth and presses the material against the fixed jaw, that in turn causes it to break down into smaller pieces.
