Um britador de cone de mola é um tipo de equipamento de britagem secundário ou terciário amplamente utilizado na mineração, metalurgia, construção, e produção agregada. It utilizes a spring-based safety system to protect the crusher from damage caused by uncrushable materials (por exemplo, ferro vagabundo) and overload conditions.

Principais recursos:
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. Configuração de descarga ajustável:
- The gap between the mantle and concave can be adjusted to control the output size of crushed material.

4. Aplicativos:
- Suitable for medium to hard rocks (por exemplo, granito, basalto, minério de ferro).
- Used in secondary or tertiary crushing stages in quarrying and mining.

5. Vantagens:
- 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, polias, or direct drive.

Comparação com britador de cone hidráulico:
| Recurso | Triturador de cone de mola | Triturador de cone hidráulico |
||||
| Proteção contra sobrecarga | Molas | Cilindros hidráulicos |
| Automação | Manual adjustment | Fully automated adjustment |
| Eficiência | Mais baixo | Mais alto (better particle shape) |
| Manutenção | Simpler | More complex |
| Custo | Lower initial cost | Higher initial cost |

Common Models:
- PY Series (por exemplo, PY900, PY1200)
- triturador de cone simons (spring-type variant)

Maintenance Tips:
- Regularly check spring tension and wear parts (manto/côncavo).
