Gyratory Crusher Operational Workflow Overview

A typical gyratory crusher workflow includes:

1. Material Feeding
   Large rocks are fed into the crusher chamber.

2. Gyratory Motion Generation
   The eccentric assembly creates a circular motion.

3. Compression Crushing
   Material is crushed between mantle and concave.

4. Size Reduction Progression
   Material moves downward as it is crushed.

5. Discharge
   Crushed material exits through the bottom opening.

6. Monitoring and Adjustment
   Settings are adjusted to control output size.

This workflow ensures continuous and efficient crushing.
