Jaw Crusher. The jaw crusher is used in primary crushing and is therefore usually installed near the mine. Crushing in this type of equipment occurs by compression and friction promoted by metal plates: one mobile and one fixed (jaws). The mobile jaw moves and compresses the fragments against the fixed jaw, crushing them.
