The section where the moving cone is close to the static cone becomes the crushing chamber. The material is crushed by multiple squeezing and impact of the moving cone and the static cone. When the moving cone leaves this section, the material that has been crushed to the required particle size falls under the action of its own gravity and is discharged from the bottom of the cone.
