Comparison of the differences between cone breaking and counterattack breaking
Cone breaking and counterattack breaking are two different types of rock crushing technologies used in the mining and construction industries. Here's a comparison of the main differences between the two:
1. **Working Principle:**
- **Cone Breaking:** Cone crushers use a gyrating cone to compress and break rock materials between the fixed cone and the moving cone. The materials are crushed by the squeezing and grinding action of the cones, and the final products are discharged through the bottom.
- **Counterattack Breaking:** Counterattack crushers use high-speed rotating hammers to impact and break rock materials, which are then thrown against a counterattack plate for further crushing. The final products are discharged through the bottom or side of the crusher.
2. **Material Properties:**
- **Cone Breaking:** Cone crushers are suitable for crushing medium-hard and hard materials, such as granite, basalt, and iron ore. They can handle high-pressure and high-strength materials due to their robust design.
- **Counterattack Breaking:** Counterattack crushers are suitable for crushing medium-hard and soft materials, such as limestone, shale, and coal. They are not suitable for materials with high hardness and high pressure resistance.
3. **Application:**
- **Cone Breaking:** Cone crushers are commonly used in the mining and construction industries for secondary, tertiary, and quaternary crushing. They are widely applied in the production of aggregate, gravel, and other construction materials.
- **Counterattack Breaking:** Counterattack crushers are primarily used in the mining and construction industries for primary and secondary crushing. They are commonly used in the production of aggregate, cement, and other construction materials.
4. **Advantages and Disadvantages:**
- **Cone Breaking:**
- Advantages: High crushing efficiency, high capacity, low energy consumption, and good product shape.
- Disadvantages: High investment cost, complex structure, and maintenance difficulties.
- **Counterattack Breaking:**
- Advantages: Simple structure, easy maintenance, low investment cost, and high crushing efficiency.
- Disadvantages: High energy consumption, large wear on the hammer and counterattack plate, and poor product shape.
In summary, cone breaking and counterattack breaking are two different types of rock crushing technologies with distinct working principles, material properties, applications, and advantages/disadvantages. The choice between the two technologies depends on the specific requirements of the crushing project, such as the hardness of the material, the desired product size, and the investment budget.
