A cone crusher is the workhorse of secondary and tertiary crushing. Choosing the wrong model means chronic bottlenecks, excessive wear costs, poor product shape, or wasted capital. This guide covers the key factors for selecting the right cone crusher for your project.
1. Two Main Types: Standard vs. Short-Head
| Parameter | Standard | Short-Head |
|---|---|---|
| Feed size | 100–300 mm | 50–130 mm |
| Product size | 13–51 mm | 5–25 mm |
| Crushing stage | Secondary | Tertiary / Fine |
| Product shape | Good | Excellent |
| Crushing ratio | 3:1 to 6:1 | 4:1 to 8:1 |
Standard — for secondary crushing after a jaw crusher. Higher throughput, coarser product.
Short-Head — for tertiary/fine crushing. Longer parallel zone produces finer, better-shaped product.
Many modern designs use interchangeable cavity liners to switch between both on the same machine.
2. Single-Cylinder vs. Multi-Cylinder Hydraulic
| Feature | Single-Cylinder | Multi-Cylinder |
|---|---|---|
| Structure | Simpler, one hydraulic cylinder | Multiple cylinders (4–8) |
| Crushing force | Moderate | Higher, more uniform |
| Capacity range | 50–800 t/h | 100–2,000+ t/h |
| Product shape | Good | Excellent |
| Maintenance | Simpler | More complex |
| Purchase price | Lower | Higher |
Choose single-cylinder when:
Capacity under 300 t/h
Medium-hard rock (limestone, dolomite)
Budget-sensitive project
Choose multi-cylinder when:
Capacity above 800 t/h
Hard, abrasive rock (granite, basalt, quartzite)
Product shape is critical (manufactured sand, high-spec aggregates)
3. Match to Your Feed Material
Rock Hardness
| Material | Hardness | Recommendation |
|---|---|---|
| Soft (limestone, gypsum) | Mohs 2–3 | Standard type; lower force sufficient |
| Medium (dolomite, marble) | Mohs 3–5 | Standard or short-head |
| Hard (granite, basalt) | Mohs 5–7 | Higher force; wear-resistant liners essential |
| Very hard (quartzite) | Mohs 7+ | Maximum force; premium alloy liners |
For abrasive materials, specify Mn18Cr2 or Mn22Cr2 liners instead of standard Mn13.
Feed Size
The cone crusher's feed opening must be at least 1.2–1.5× the maximum lump size from the upstream jaw crusher. A common mistake is pairing a large jaw with a small cone — creating a bottleneck.
Moisture and Clay
Feed with >5% moisture or clay content causes buildup. Pre-screen to remove fines before the cone crusher.
4. Define Capacity and Product Requirements
Required throughput — always specify at YOUR target product size, not at a coarse setting. A crusher may produce 500 t/h at 50 mm CSS but only 280 t/h at 19 mm.
Product size:
25–51 mm → Standard cavity, wider CSS
5–19 mm → Short-head cavity, narrower CSS
0–5 mm (manufactured sand) → Short-head at tight CSS, or add a VSI crusher
Product shape improves with: longer parallel zone (short-head), choke feeding, and multi-cylinder design.
5. Select the Right Cavity
Most manufacturers offer multiple cavity options per model:
| Cavity | Feed Opening | CSS Range | Throughput | Product |
|---|---|---|---|---|
| Extra Coarse (EC) | Largest | 19–38 mm | Highest | Coarsest |
| Coarse (C) | Large | 13–32 mm | High | Coarse |
| Medium (M) | Medium | 10–25 mm | Moderate | Medium |
| Fine (F) | Smaller | 6–19 mm | Lower | Fine |
| Extra Fine (EF) | Smallest | 3–13 mm | Lowest | Finest |
Always request capacity curves for each cavity option plotted for your specific material — do not rely on a single brochure number.
6. Key Specifications to Compare
| Specification | What to Check |
|---|---|
| Feed opening | Must exceed max feed lump size |
| CSS range | Must include your target product size |
| Crushing force (kN) | Higher for harder rock |
| Motor power (kW) | Must match throughput and rock hardness |
| Throughput at target CSS | The number that matters — at YOUR product size |
| Liner material & life | Mn13, Mn18Cr2, Mn22Cr2 — directly affects operating cost |
7. Match to Your Crushing Circuit
Upstream Pairing
| Jaw Crusher | Typical Cone Crusher |
|---|---|
| PE-600×900 | 3 ft / HST160 / HP200 class |
| PE-750×1060 | 4¼ ft / HST250 / HP300 class |
| PE-900×1200 | 5½ ft / HST315 / HP400 class |
| PE-1200×1500 | 7 ft / HST500 / HP500 class |
Closed-Circuit Operation
Most cone crushers run in closed circuit with a vibrating screen — oversize returns to the crusher, undersize goes to stockpile or next stage. Ensure your screen capacity matches the crusher throughput.
8. Think Total Cost, Not Purchase Price
Over 10 years, typical cost breakdown:
| Cost | Share |
|---|---|
| Equipment purchase | 15–25% |
| Liner replacement | 25–35% |
| Energy | 15–25% |
| Maintenance | 10–15% |
| Downtime | 10–20% |
A cheaper crusher with shorter liner life and higher energy consumption will cost more in the long run. Ask your supplier about liner life, specific energy consumption (kWh/ton), and recommended maintenance schedule for your material.
9. Quick Selection Checklist
| # | Question |
|---|---|
| 1 | What is your feed material and compressive strength? |
| 2 | Maximum feed lump size from upstream crusher? |
| 3 | Does feed contain soil, clay, or moisture? |
| 4 | Required throughput (t/h)? |
| 5 | Required product size (mm)? |
| 6 | Secondary or tertiary application? |
| 7 | Is product shape critical? |
| 8 | Upstream crusher model and output? |
| 9 | Available power supply (voltage, frequency)? |
| 10 | Budget — purchase price only or total cost of ownership? |
