Jaw vs Impact vs Cone Crusher: Choosing the Right Crusher for Your Material

A jaw crusher in a recycled-asphalt yard is the wrong tool. So is a cone crusher chasing oversize granite. Match the crusher type to the feed material and your product spec, or you'll spend more on wear parts and downtime than you save buying the cheaper machine.

The three crusher types in one paragraph

Jaw crushers compress rock between a fixed and a moving plate — primary reduction, hard rock, big top size. Cone crushers compress rock between a rotating mantle and a concave bowl — secondary and tertiary reduction, tighter product spec, lots of fines control. Impact crushers hit the rock with hammers attached to a fast-rotating rotor — softer material, high reduction ratio, lots of fines, good shape.

That's the executive summary. The rest of this post is when each one wins, and what to look for when buying used.

Jaw crushers: primary reduction on hard rock

Jaws are the workhorse primary on every aggregate quarry. They take massive feed (typically 80% of the feed opening size) and reduce it by a factor of 4-6 in a single pass. The output is angular and inconsistent in shape — that's fine for primary product going into a secondary, less fine if your jaw is your only crusher.

When to use a jaw

• Primary reduction in any aggregate quarry (granite, limestone, basalt, trap rock)
• Portable C&D recycling where feed material is unpredictable
• Recycled concrete with rebar (jaws handle rebar; cones don't)
• Pre-screening output going to a secondary cone or impact crusher

When NOT to use a jaw

• You need cubical, well-shaped final product (jaws produce slabby material)
• Your feed is already small enough for a secondary crusher
• You're trying to make sand or fines — wrong tool entirely

What to look for buying used

Toggle plate condition, jaw die wear (manganese steel — measurable in pounds remaining), pitman bearing condition, hydraulic CSS adjustment functionality. Listen to the machine running under load on inspection — knocking sounds in the pitman are a $20-40K rebuild.

Common used jaws we broker: Metso C series (LT106, LT120), McCloskey J-series, Powerscreen Premiertrak, Terex Finlay J-series, Eagle, Lippmann.

Cone crushers: secondary, tertiary, tight spec

Cones earn their keep when you need consistent product spec. The mantle and concave geometry produces well-shaped, cubical product, and modern cones can hold tight CSS tolerance (down to 6-8mm) under load. They're the standard secondary in aggregate operations producing salable specced product.

When to use a cone

• Secondary or tertiary reduction in aggregate plants
• Producing tight-spec products (1/2", 3/4", 1" road base, etc.)
• High-volume operations where wear-part economics favor cone over impact
• Finishing crushers in any multi-stage circuit

When NOT to use a cone

• Recycled concrete with any rebar — rebar destroys cone mantles
• Wet, sticky, or dirty feed (cones pack and choke)
• Single-stage operations where you need to take big feed to small product

What to look for buying used

Mantle and concave wear — these are bolt-on liners measured in mm of remaining material. Hydroset / spring relief functionality. Lubrication system condition (these run on constant oil flow). Crusher hours separate from engine hours on tracked units.

Common used cones we broker: Metso HP (HP200, HP300, HP400), Sandvik CH/CS series, McCloskey C series, Powerscreen 1000/1300 Maxtrak.

Impact crushers: recycled material and shape

Impact crushers (HSI in particular) shine on softer material and recycled feed where you want high reduction ratio and good shape from a single machine. They're the standard for recycled concrete and asphalt operations because they handle contamination better than cones and produce well-shaped product unlike jaws.

HSI vs VSI

HSI (horizontal shaft impactor) — material is fed onto a horizontal rotor and smashed against a curtain. Common for recycled concrete (RCA), recycled asphalt (RAP), softer aggregate (limestone). Wear part: blow bars (replaceable, $1-3K per set).

VSI (vertical shaft impactor) — material drops into a vertical rotor and gets thrown out at high speed, hitting either anvils or other rock. Used for sand production, shape correction (making cubical aggregate from slabby feed), and manufactured-sand operations. Wear part: rotor tips and anvils.

When to use an impact crusher

• Recycled concrete and asphalt processing
• Soft aggregate (limestone, dolomite) where high reduction matters
• Single-machine operations needing big feed to small product
• Shape correction (VSI) on slabby aggregate
• Manufactured sand production (VSI)

When NOT to use an impact crusher

• Hard, abrasive rock (granite, basalt) — blow bars wear too fast
• High-fines operations where dust generation is unacceptable
• Tight CSS spec at high volume — cones hold spec better

What to look for buying used

Blow bar condition (HSI) or rotor tip / anvil condition (VSI). Rotor balance — out-of-balance rotors destroy bearings fast. Curtain liner wear. Hydraulic gap adjustment functionality.

Common used impactors we broker: Sandvik QI series, McCloskey I-series (I44, I54), Kleemann MR series, Eagle, Lippmann.

The application matrix

Bottom line

If you're crushing hard rock, lead with a jaw and follow with a cone. If you're recycling concrete or asphalt, lead with an HSI impact (with a jaw upstream if rebar is present). If you need shape or sand from existing crushed product, finish with a VSI.
