Granite Geological Profile
As the primary component of continental crust, granite is an intrusive igneous rock formed through subsurface magma crystallization. This durable material exhibits exceptional mechanical properties that make it ideal for industrial processing:
Mohs Hardness: 6-7
Compressive Strength: 150-300 MPa (ASTM D7012 certified)
Weathering Resistance: Maintains structural integrity and color retention for over 100 years
Industrial Applications & Value
✓ Premium architectural cladding and monumental carving applications
✓ 15-25% property value enhancement compared to synthetic materials
✓ Critical raw material for multiple industries:
Cement production (as crushed aggregate)
Rock-fill dam construction (≤500mm riprap)
High-temperature resistant countertops
Three-Stage Crushing Process Flow
Stage 1: Primary Crushing
Oversized granite boulders (<1200mm) are uniformly fed via vibrating grizzly feeder to the jaw crusher for initial size reduction. The output yields fragments ≤250mm, with oversize material recirculated through vibrating screen for secondary processing.
Stage 2: Intermediate Crushing
The ≤250mm feed enters hydraulic cone crusher for secondary processing, producing particles ≤40mm. This stage operates with closed-circuit control, ensuring optimal particle size distribution and system efficiency.
Stage 3: Sand Making & Final Shaping
Material ≤40mm advances to VSI sand maker for tertiary processing and particle shaping. The output undergoes precise grading:
✓ ≥20mm particles: Recirculated for additional crushing
✓ <20mm particles: Screened and optionally washed to produce premium granite sand
Final Product Specification
The system yields high-quality construction materials:
0-5mm: Fine granite sand for concrete and mortar
5-20mm: Premium aggregate for structural applications
This optimized configuration ensures maximum material utilization while producing consistently graded, cubical particles suitable for high-value construction applications.
