In mining and construction industries, mastering stone crusher specifications is crucial for operational efficiency. This guide explores technical details—crusher types, performance parameters, selection strategies—with SBM China model comparisons, maintenance tips, and critical factor analysis. Whether you’re processing granite or limestone, precise specifications ensure maximum ROI and minimal downtime.

Understanding Stone Crushers and Their Function

Stone crushers break large rocks into construction aggregates (gravel, sand). Essential for infrastructure projects, they transform raw materials like basalt or andesite into usable sizes. Correct technical specifications directly impact productivity and cost-efficiency.

Why Specifications Matter: Avoid Costly Mistakes

Incorrect specs lead to catastrophic costs:

• Undersized capacity → Production bottlenecks

• Mismatched output size → Unmarketable products

• Weak motor power → Overheating on hard rocks
  Accurate crusher specifications prevent operational failures and boost profitability.

Crusher Types by Specifications

Each crusher type serves unique purposes:

Jaw Crusher Specifications (Primary Crushing)

Ideal for hard rocks (granite/basalt). Uses compressive force.

Table: SBM Jaw Crusher Specs (PE Series)

Note: Capacity varies with rock hardness and moisture.

Impact Crusher Specifications (Secondary Crushing)

Produces cubical aggregates via impact force. Best for limestone/sedimentary rocks.

Table: SBM Impact Crusher Specs (PF Series)

Cone Crusher Specifications (Tertiary Crushing)

Delivers fine output (0-5mm). Uses gyrating compression.

4 Key Factors for Choosing Crusher Specs

1. Material Hardness

   • Granite/basalt → Prioritize jaw crushers (≥132 kW)

   • Limestone → Opt for impact crushers

2. Required Capacity
   Small sites (<100 t/day): PE-600×900. Large quarries: HPT-300

3. Output Size Needs
   0-5mm aggregates? Cone crushers are mandatory

4. Operating Environment
   Dusty/wet sites? Choose sealed bearings and dust suppression systems

Practical Selection Tips

From industry experience:

1. Audit Needs: Calculate daily volume, input size, and desired output

2. Compare Technical Data: Use tables above. Need 200 t/h? Consider PE-900×1200

3. Test Your Material: Bring samples to suppliers for crushing trials

4. Verify After-Sales Support: Ensure spare parts availability

I once chose the wrong crusher—our project stalled for 2 weeks! Always request demos now.

Maintenance: Keep Specs Performing Optimally

Prevent failures with:

• Daily: Check bearing lubrication and bolt tightness

• Weekly: Clear jammed material from crushing chambers

• Monthly: Replace wear parts (jaws, hammers) with genuine SBM parts

• Annually: Schedule certified technician calibration

*$200/month maintenance prevents $2,000 repairs!*

Conclusion: Precision Specs = Peak Performance

Selecting stone crusher specifications isn’t about data sheets—it’s matching equipment to your project’s DNA. Follow this guide, consult SBM China experts, and test rigorously. With precise technical parameters, your investment will deliver lasting returns. Crush smart!
