1. Core Equipment Configuration

 

Primary Crushing Stage

 

Jaw Crusher: Handles large granite blocks (≤1300mm) and outputs coarse aggregates (≤300mm) .

Example models: JC200 (feed size ≤1300mm, output ≤300mm) .

 

Secondary Crushing Stage

 

Cone Crusher: Processes coarse aggregates into medium/fine particles (≤45mm) using layer-pressure crushing for uniform grain shape .

Example models: HPY300 Multi-Cylinder Hydraulic Cone Crusher (output ≤45mm, adjustable) .

 

Tertiary Crushing & Sand-Making Stage

 

Vertical Shaft Impact (VSI) Crusher: Shapes granite into high-quality sand (0-5mm) with low needle-flake content (<10%) .

Example models: PLS-1400Ⅱ (feed size ≤60mm, adjustable powder content: 5%-15%) .

2. Auxiliary Equipment

 

Feeding & Screening

 

Vibrating Feeder: Ensures uniform material flow (e.g., ZSW600×130) .

Circular Vibrating Screen: Classifies aggregates into multiple specifications (e.g., 0-5mm, 5-10mm) .

 

Washing & Dewatering

 

Sand Washer: Removes impurities (e.g., mud, dust) to produce clean sand (mud content ≤3%) .

Example models: DXS4224 Wheel Bucket Sand Washer (capacity: 300t/h) .

 

Conveying System

 

Belt Conveyors: Connect all stages for continuous material transfer (e.g., B1000 type) .

3. Optional Process Designs

 

Three-Stage Crushing:

Jaw Crusher + Cone Crusher + VSI Crusher + Two-stage Screening → Ideal for high-quality sand with strict grain shape requirements .

 

Simplified Configuration:

Jaw Crusher + Impact Crusher → Suitable for producing small-sized石子 (e.g., ≤30mm) without sand-making needs .

 

4. Smart & Eco-Friendly Solutions

Dust Control: Pulse bag dust collectors (emission <10mg/m³) and enclosed conveyor corridors reduce pollution .

Automation: PLC control systems and mobile app monitoring for real-time parameter adjustments and fault alerts .

 

This configuration of granite crushing production line balances efficiency, product quality, and environmental compliance, adaptable to various output specifications.
