Jaw Crusher:crusherzone.comr Operating principle:

The motor drives the belt wheel, and makes movable jaw up and down by eccentric shaft. When the movable jaw rises, the angle between the fixed jaw and movable jaw gets larger, and the materials can be crushed to reach the crushing target. When the movable jaw is down, the angle between the fixed jaw and movable jaw becomes smaller. The movable jaw plate leaves the fixed jaw plate under the function of drawbar and spring, and then the crushed materials are discharged from the lower outlet of the crushing cavity.
