Jaw crusher vs cone crusher crushing principle difference
1. Jaw Crusher — Blasting + Squeezing Crushing (Intermittent)
Crushing principle It uses a movable jaw plate to perform periodic reciprocating motion against the fixed jaw plate. When the moving jaw swings toward the fixed jaw, the ore inside the crushing cavity is squeezed, bent and split to break; when the moving jaw swings away, broken materials fall down by gravity from the discharge opening.
- Working mode: intermittent crushing (one squeeze, one discharge cycle)
- Force type: Mainly compressive force, supplemented by bending and splitting force
- Cavity shape: Deep V-shaped crushing chamber
- Feed & discharge: Suitable for large raw ore; coarse crushing (primary crushing)
2. Cone Crusher — Gyroscopic Squeezing Crushing (Continuous)
Crushing principle The mantle (movable cone) is installed eccentrically inside the concave (fixed cone liner). Driven by the eccentric sleeve, the mantle does gyratory pendulum movement. It continuously presses, grinds and impacts materials between mantle and concave ring. Materials are crushed layer by layer, and qualified particles drop out when the gap becomes larger.
- Working mode: continuous crushing (no pause in the whole circle)
- Force type: Compression + shear + grinding force
- Cavity shape: Inverted conical crushing chamber
- Feed & discharge: Medium/fine crushing (secondary & tertiary crushing); smaller feeding size, finer finished product
Core Comparison Table
| Item | Jaw Crusher | Cone Crusher |
|---|---|---|
| Crushing motion | Reciprocating swing of movable jaw | Gyratory eccentric swing of inner cone |
| Working rhythm | Intermittent | Continuous |
| Dominant crushing force | Compression, bending, splitting | Compression, shear, grinding |
| Typical stage | Primary coarse crushing | Secondary medium / fine crushing |
| Material feeding size | Large | Relatively small |
| Product shape | More flaky particles | Better cubic shape |
Supplementary Notes
- Jaw crusher handles big block raw rock, high capacity for coarse breaking, simple structure.
- Cone crusher produces better aggregate grain shape, less needle-flake material, widely used for sand and aggregate finished crushing.
