A Spring Cone Crusher is a type of secondary or tertiary crushing equipment widely used in mining, metalurgia, construcción, y producción agregada. It utilizes a spring-based safety system to protect the crusher from damage caused by uncrushable materials (p.ej., hierro vagabundo) and overload conditions.

Características clave:
1. Spring Release System:
- Acts as an overload protection mechanism. When uncrushable material enters the crushing chamber, the springs compress, allowing the mantle to lift and discharge the foreign object without damaging the machine.

2. Crushing Principle:
- Operates on a gyratory motion where the mantle gyrates against the concave (fixed liner), compressing and breaking rocks into smaller pieces.

3. Configuración de descarga ajustable:
- The gap between the mantle and concave can be adjusted to control the output size of crushed material.

4. Aplicaciones:
- Suitable for medium to hard rocks (p.ej., granito, basalto, mineral de hierro).
- Used in secondary or tertiary crushing stages in quarrying and mining.

5. Ventajas:
- Reliable and durable design.
- Lower maintenance compared to hydraulic cone crushers (but less advanced in automation).
- Cost-effective for small to medium-scale operations.

Componentes:
- Main Frame – Supports the crushing mechanism.
- Eccentric Shaft – Drives the gyratory motion of the mantle.
- Manto & Concave – Wear parts that directly crush materials.
- Springs – Provide tension and safety release.
- Transmission System – Includes belts, pulleys, or direct drive.

Comparison with Hydraulic Cone Crusher:
| Característica | trituradora de cono de primavera | trituradora de cono hidraulica |
||||
| Protección contra sobrecarga | Ballestas | Hydraulic cylinders |
| Automatización | Manual adjustment | Fully automated adjustment |
| Eficiencia | Más bajo | Más alto (better particle shape) |
| Mantenimiento | Más simple | Más complejo |
| Costo | Menor costo inicial | Higher initial cost |

Common Models:
- PY Series (p.ej., PY900, PY1200)
- trituradora de cono symons (spring-type variant)

Maintenance Tips:
- Regularly check spring tension and wear parts (mantle/concave).
