Many people engaged in sand and aggregate and ore processing struggle to choose between a cone crusher and an impact crusher. To be honest, neither is absolutely superior. The choice mainly depends on the hardness of raw stone, finished product requirements and budget. Let’s make a clear comparison today.
## Difference in Core Crushing Principles
**Cone Crusher**: Lamination compression crushing. The cone head performs gyratory motion inside the cone bowl, and stones are crushed under compression and grinding.
**Impact Crusher**: Impact crushing. The rotor rotates at high speed; blow bars strike the stones, which then hit the impact plates and get broken repeatedly by impact force.
## Suitable Working Conditions for Each Type
### When to Choose a Cone Crusher
- Processing high-hardness ores: hard materials such as granite, basalt, iron ore and river pebble.
- Secondary crushing stage with high output requirement and the need to reduce replacement of wear parts.
- Stable finished product required, with an acceptable content of flaky and elongated particles, no strict demand for sharp edges of aggregates.
**Advantages**: Low consumption of wear-resistant parts, stable continuous operation, suitable for long-time production and high single-machine capacity.
**Disadvantages**: Relatively high content of flaky and elongated particles, ordinary particle shape; not suitable for wet and sticky materials which may cause blockage; higher initial purchase cost.
### When to Choose an Impact Crusher
- Medium and low hardness materials: limestone, weathered rock, construction waste, coal gangue.
- High requirements on aggregate shape: sand and stone for road construction and ready-mixed concrete that need well-angled grains and low flaky content.
- Limited budget with low expectation for upfront investment.
**Advantages**: Good particle shape with more cubic finished grains; lower equipment price and convenient adjustment of discharge size.
**Disadvantages**: Blow bars wear rapidly when crushing hard ores, requiring frequent replacement and leading to high later maintenance cost; limited capacity for large hard stones.
