Jaw Crusher: What Is It & How Does It Work?
A jaw crusher is a machine that breaks down large rocks into smaller pieces of rock, gravel, or dust. It does this by placing two jaw plates perpendicular to each other and squeezing the rock between them until it is broken into small pieces. A stationary jaw plate and a movable jaw plate control the movement of these jaw plates.
