Cone or Impact Crusher for the Secondary Stage?

Choose a cone crusher for hard, abrasive rock (granite, basalt) and an impact crusher for soft-to-medium, non-abrasive stone (limestone). General Makina manufactures both.

Choosing the right secondary crusher directly shapes your operating cost and product quality. General Makina manufactures both cone crushers and impact crushers; this page compares the two types from a buying-decision standpoint. The right choice depends on the hardness and abrasivity of the material you crush.

Criterion	Cone Crusher	Impact Crusher (HSI)
Material hardness / abrasivity	Hard, abrasive rock (granite, basalt)	Soft-to-medium, non-abrasive (limestone)
Crushing principle	Compression	Impact
Product shape	Good, near-cubical	More cubical
Reduction ratio	Moderate	High
Wear-part cost	Low on abrasive rock	High on abrasive rock
Application	Hard rock, mining	Limestone, recycling

Decision by scenario

For abrasive hard rock: choose cone.
For soft, non-abrasive limestone: choose impact.
If high reduction ratio and the most cubical shape are your priority: choose impact.
If low wear cost is your priority and the rock is abrasive: choose cone.

You can select the right model from our full range of crushers, or if you need on-site flexibility, review our mobile stone crushers.

Can I run an impact crusher on abrasive granite?

It is technically possible, but wear parts on abrasive rock deplete quickly; a cone crusher is more economical for such material.

Which crusher gives the most cubical aggregate?

An impact crusher usually produces a more cubical product, but it stays economical only on soft-to-medium, non-abrasive stone.

Can I use both types in one plant?

Yes; we can design a staged setup matched to your material and target product.
