Jaw Crusher or Cone Crusher: How to Select for Aggregate Plant

What is a jaw crusher?

What is a cone crusher?

A cone crusher is generally used as a secondary or tertiary crushing equipment. It compresses rocks by a rotating mantle inside a concave bowl. The continuous gyratory squeezing action gradually reduces the material to finer particles. It usually works after the jaw crusher in a complete crushing circuit.

♦Ideal for producing clean, cubical aggregate with precise particle size

♦Best suited for hard rock to make high-quality finished aggregate

♦Capable of fine output, down to 6 mm

♦High crushing speed for stable continuous operation

♦Strict requirements for feed material: clean and pre-sized raw ore

Working Principle: Squeeze vs Squeeze-and-Grind

A jaw crusher uses two vertical plates - one fixed, one moving - to compress rock between them. Material is crushed when the movable jaw presses it against the fixed jaw. It works purely by compression, which makes it ideal for the hardest, most abrasive rocks.

A cone crusher also uses compression, but with a different mechanism. Rock is squeezed between a rotating mantle and a fixed concave bowl. The crushing chamber narrows from top to bottom, so material is crushed and re-crushed as it moves downward through multiple zones.

In short: jaw crushers crush in one pass with a simple up-and-down motion; cone crushers crush continuously in a rotating, multi-stage chamber.

Feed Size: The Biggest Difference

This is usually the deciding factor.

Jaw crusher - accepts very large feed, typically up to 1,000–1,200 mm for primary crushing. It is the machine that takes blasted quarry rock straight from the pit.

Cone crusher - requires pre-crushed feed, normally below 200–300 mm. A cone crusher cannot accept run-of-mine rock; it must be fed by a primary crusher or a feeder with controlled size.

Rule of thumb: if your material comes from blasting and exceeds 400 mm, you need a jaw crusher (or another primary crusher) first. A cone crusher is rarely a primary machine.

Output Shape and Particle Quality

Jaw crusher produces a more elongated, flaky product with higher content of flat particles. It is acceptable for road base and general aggregates, but not ideal for high-quality concrete or asphalt aggregate.

Cone crusher produces a more cubic, well-graded product. The multi-layer crushing action rounds off particles, giving better shape. For concrete aggregate and asphalt specifications, a cone crusher (often combined with a VSI) is the preferred choice.

If your client's specification requires low flakiness index, plan a secondary/tertiary cone stage rather than relying on a jaw crusher alone.

Common Applications

Both are essential in most hard-rock aggregate plants. They are complementary, not competing - most plants run both.

How to Select: 4 Quick Questions

What is your max feed size? Over 400 mm → jaw crusher as primary.

What product do you need? Concrete/asphalt aggregate → add a cone stage.

What capacity? Match the crusher model to your target t/h, not the biggest available.

What is your budget? Start with a well-matched jaw+cone line; don't oversize.

Still unsure? Send us your material test, feed size, and target output, and our engineers will recommend a complete crushing line - browse our PE series jaw crusher for primary rock crushing and cone crusher models for secondary crushing, or contact us for a free selection consultation.

Besides rock and aggregate crushing, our crushers are also widely applied in waste material recycling. You can read our guide about Can Crushing Equipment Be Used For Glass Recycling? to learn more.

Final Verdict

Choose a jaw crusher when you need primary crushing of large, hard rock.

Choose a cone crusher when you need secondary/tertiary crushing with cubic output.

Choose both for a complete, efficient aggregate plant - this is what most successful plants do.

Our Practical Tips For Quarry & Mining Project Selection

When you configure a crushing line with our jaw and cone crushers, we often remind clients of these real-site points:

1. If your raw rock size exceeds 600mm, jaw crusher is mandatory as primary crushing equipment. A cone crusher cannot handle oversized feed.

2. For high-hardness granite, basalt ore, the combination of our PE jaw crusher + spring cone crusher can reduce liner wear and cut operating cost.

3. If your target output is less than 100t/h, a simple jaw crusher alone may meet demand, no need to add extra cone crusher.

4. Sticky, wet materials are not suitable for cone crushing, as blockage inside crushing chamber will frequently happen. Our team can calculate and recommend the matched crushing combination according to your ore hardness, feed size and required capacity.
