In this article, you’ll discover:
✅ How impact crusher works – working principle
✅ How to judge material hardness for impact crusher
✅ Capacity requirements – small, medium, large
✅ Mobile impact crusher vs stationary – which to choose?
Step 1: Understand Impact Crusher Working Principle
How Does an Impact Crusher Work?
The impact crusher uses high-speed rotating rotor to crush materials through impact force rather than compression.
Working Process:
1. Stone materials fall directly from feed inlet into large-capacity crushing chamber
2. High-speed rotating turntable accelerates materials with centrifugal force
3. Materials collide with stones flowing around turntable in umbrella pattern
4. High-speed collision and high-density crushing occurs
5. Materials create vortex motion between turntable and machine shell
6. Multiple mutual impacts, friction, and crushing
7. Discharged directly from bottom
8. Form closed-circuit multiple cycles
9. Screening equipment controls required particle size
Key Advantages of Impact Crusher
- ✅ High reduction ratio (up to 10:1)
- ✅ Excellent particle shape (cubical)
- ✅ Perfect for recycling applications
- ✅ Lower operating costs
- ✅ Easy maintenance
Step 2: Judge Material Hardness ⭐
Not all materials are suitable for impact crusher. Material hardness is the first factor to consider.
Suitable Materials for Impact Crusher
| Material Type | Hardness | Suitable for Impact Crusher? |
|---|---|---|
| Limestone | Medium (f=4-6) | ✅ Yes – Excellent |
| Construction Waste | Variable | ✅ Yes – Excellent |
| Bluestone | Medium (f=4-6) | ✅ Yes – Good |
| Coal | Soft (f<4) | ✅ Yes – Excellent |
| Concrete | Variable | ✅ Yes – Good (recycling) |
| Asphalt | Medium | ✅ Yes – Excellent |
| Granite | Hard (f>8) | ❌ No – Use Jaw + Cone |
| Basalt | Hard (f>8) | ❌ No – Use Jaw + Cone |
| River Pebbles | Hard (f>8) | ❌ No – Use Cone Crusher |
Check Mud Content and Moisture
Important Considerations:
□ Mud content should be <15%
□ Moisture content should be <15%
□ High mud/moisture may cause clogging
□ Solution: Pre-screening or choose larger crusher
Pro Tip: For medium-hard rock and soft rock, impact crusher is the best choice. For hard rock (granite, basalt), choose jaw + cone crusher combination.
Step 3: Check Material Size
The feed size must match your impact crusher specifications.
SUHMAN SF-380D Impact Crusher – Feed Specifications
| Specification | SF-380D |
|---|---|
| Max Feed Size | <700mm |
| Feed Inlet Size | 1380×970mm |
| Feeding Capacity | 230 TPH |
Feed Size Guidelines
| Material Size | Recommended Solution |
|---|---|
| <700mm | Direct feeding to impact crusher |
| 700-1000mm | Need primary jaw crusher first |
| >1000mm | Need heavy-duty jaw crusher + impact crusher |
Step 4: Determine Capacity Requirements
Choose impact crusher capacity based on your hourly production needs.
Capacity Classification
| Project Scale | Required Capacity | Recommended Model |
|---|---|---|
| Small | 50-150 TPH | SF-380D (150-180 TPH) |
| Medium | 150-200 TPH | SF-580D (180-230 TPH) |
| Large | 200+ TPH | Multiple crushers or heavy-duty model |
Calculate Your Needs
Daily Production Goal ÷ Working Hours = Required TPH
Example:
1500 tons/day ÷ 10 hours = 150 TPH required
Pro Tip: Add 20-30% buffer for peak demands
150 TPH × 1.25 = 187.5 TPH **impact crusher** recommended
Step 5: Define Finished Product Specifications
The impact crusher discharge size determines your final product quality.
SUHMAN Impact Crusher – Discharge Specifications
| Model | Discharge Size Range | Output Options |
|---|---|---|
| SF-380D | 0-10mm, 10-20mm, 20-40mm | 2-3 sizes simultaneously |
| SF-580D | 0-10mm, 10-20mm, 20-40mm | 2-4 sizes simultaneously |
Multi-Size Output Capability
SUHMAN integrated impact crusher can produce multiple sizes simultaneously:
✅ 2 sizes: 0-10mm + 10-20mm
✅ 3 sizes: 0-10mm + 10-20mm + 20-40mm
✅ 4 sizes: Customizable based on screening configuration
Ideal for:
- Road construction (multiple aggregate sizes)
- Concrete production (graded aggregates)
- Quarry operations (diverse product range)
Step 6: Crushing Line Configuration
Based on capacity and finished product requirements, determine if you need additional equipment.
Complete Crushing Line Options
| Configuration | Equipment Combination | Best For |
|---|---|---|
| Primary + Secondary | Jaw Crusher + Impact Crusher | Medium-hard rock |
| Three-Stage | Jaw + Impact Crusher + Screening | Quarry operations |
| Sand Making | Jaw + Cone + Vertical Shaft Impact Crusher SC-85D | Manufactured sand |
| Recycling Line | Mobile Impact Crusher + Screening | Construction waste |
When to Add Additional Equipment
□ Need sand production? → Add **vertical shaft impact crusher SC-85D**
□ Hard rock secondary crushing? → Add cone crusher
□ Multiple product sizes? → Add screening plant
□ High mud content? → Add washing system
Step 7: Choose Mobile vs Stationary Impact Crusher
This is one of the most important decisions when buying impact crusher for sale.
