The Mechanics of Crushing: Understanding the Jaw Crusher Working Principle
The jaw crusher exerts pressure on the materials that are to be crushed, compressing them between two cones. This action breaks the materials into smaller fragments that are easier for further processing. The jaw crusher's working principle is based on the reciprocatory movement of the fixed and movable jaw plates.
