1. Production Line Introduction

Granite is one of the hardest and most abrasive rocks. Thus, a cone crusher based on laminated crushing is the optimal solution for intermediate and fine crushing stages.

  • Feeding System:
    • Vibrating Feeder: Ensures uniform material supply to the primary crusher
  • Primary Crushing:
    • Jaw Crusher: Acts as the primary crusher, utilizing powerful compressive force to break large granite blocks (feed size up to 500–600 mm) into intermediate sizes (e.g., 150–250 mm). Its robust structure suits initial granite processing
  • Intermediate/Fine Crushing:
    • Cone Crusher: The core of the line. It receives material from the jaw crusher and crushes granite through laminated compression between the mantle and concave. This principle minimizes wear compared to impact crushing, making it ideal for granite
  • Screening and Conveying:
    • Multi-layer Vibrating Screen: Forms a closed-circuit loop with the cone crusher. Screens classify crushed material by size: qualified aggregates are conveyed out, while oversized particles return via a feedback conveyor for re-crushing, maximizing output and granularity control
    • Belt Conveyors: Transport materials between stages.
  • Control System:
    • Integrated electric control for intelligent, safe operation

Typical Workflow:
Granite → Vibrating Feeder → Jaw Crusher (Primary) → Belt Conveyor → Cone Crusher (Secondary/Tertiary) → Belt Conveyor → Multi-layer Screen → Qualified Aggregates (e.g., 0–5 mm, 5–10 mm, 10–20 mm, 20–31.5 mm) → Oversized Material Returns to Cone Crusher.

2. Features and Advantages

① Core Advantage: Extreme Wear Resistance & Low Operating Costs

  • High Abrasion Resistance: Cone crusher wear parts (mantle, concave) use high-manganese or alloy steel, designed for hard rock. Their lifespan far exceeds that of impact crusher hammers when processing granite, reducing replacement frequency and costs
  • Controllable Operating Costs: For a 200 t/h scale, impact crusher hammers may require replacement within days, while cone crusher parts last weeks or longer, ensuring continuous production and economic efficiency

② Stable Operation & Reliable Output

  • Laminated Crushing Principle: Compression-based crushing ensures stable operation with minimal vibration and low failure rates, guaranteeing consistent 200 t/h output
  • 24/7 Suitability: Ideal for large quarries requiring continuous operation

③ Adjustable Product Size & Moderate Shape

  • Flexible Granularity Control: Hydraulic adjustment of the cone crusher’s discharge outlet allows flexible sizing for multi-spec aggregates
  • Moderate Particle Shape: Particle shape from cone crushers is superior to jaw crushers but less cubic than impact crushers. Needle-flake content remains acceptable for high-standard concrete aggregates. For stricter requirements, a multi-cylinder hydraulic cone crusher can optimize shape

④ Mobility Advantages

  • Flexible Relocation: Mobile design suits multi-site operations
  • Rapid Deployment: Saves infrastructure and transportation costs.
  • Eco-Integration: Includes dust removal and noise reduction systems

3. Customer Feedback & Typical Applications

Large Granite Quarry Owner:

“We prioritize long-term stability and cost. Previously, impact crushers wore out hammers too fast, halting production for replacements. After switching to this cone crusher line, though pricier initially, wear parts last significantly longer. Total costs dropped, and output remains stable.”

Highway/Railway Aggregate Supplier:

“National key projects demand strict aggregate shape and strength. This cone crusher line produces granite aggregates that fully comply with standards. Its reliability in long-term supply was crucial to our project bid success.”

Equipment Manager:

“Automation simplifies operation. The hydraulic cavity-clearing function quickly resolves blockages—unlike manual methods. Maintenance alerts reduce our workload significantly.”
