Primary Crusher vs. Secondary Crusher: Understanding Their …
The primary crusher's function is to reduce the size of the rock or stone for easier handling and transportation. The primary crusher is usually a jaw crusher or a gyratory crusher, which operates by compressing the material between two surfaces. The jaw crusher works by moving the material between a fixed and a moving plate.
