Granite and basalt, known for their high hardness and abrasiveness, demand robust crushing solutions to achieve optimal particle shape and minimize needle-like flakes. For industries prioritizing cubic aggregates with ≤5% needle flakes, LIMING Heavy Industry’s PFW/PF Series Impact Crushers stand out as the ideal choice.
Why Choose LIMING’s Impact Crusher?
Optimized Rotor Design
LIMING’s impact crushers feature a heavy-duty rotor structure with high rotational inertia, ensuring stable operation even under extreme loads. The wedge-fixed plate hammers enhance durability and simplify maintenance . This design is critical for crushing granite/basalt, as it minimizes flake formation while maximizing throughput.
Adjustable Discharge & Low Flake Ratio
Equipped with a hydraulic or mechanical adjustment system, these crushers allow precise control over output size (0–10 mm) while maintaining needle flakes below 5%. The multi-crushing chamber configuration further refines particle shape .
Superior Wear Resistance
High-chromium alloy plate hammers and manganese steel liners ensure extended service life in abrasive environments. For example, the PF1315 model handles up to 350 MPa compressive strength materials, making it perfect for granite/basalt processing .
High Efficiency & Energy Savings
With capacities up to 480 t/h (PFW1415II) and motor power optimized for minimal energy consumption, LIMING’s crushers reduce operational costs while delivering consistent output .
Technical Highlights
Feed Size: ≤700 mm (e.g., PFW1318II handles 700 mm basalt blocks)
Output: 70–480 t/h (adjustable for coarse/fine crushing)
Motor Power: 90–375 kW (varies by model)
Applications: Quarries, highways, concrete mixing plants, and mining projects .
Case Study: Successful Deployments
A limestone quarry in Guizhou, China, achieved a 1,000 t/h production line using LIMING’s PF1315 impact crusher, producing uniform aggregates for highway construction. Similarly, a Shanxi coal gangue processing plant reported a 30% reduction in maintenance costs after adopting PFW1415II for high-volume basalt crushing .
LIMING’s heavy-duty impact crushers combine advanced engineering with reliability to meet the strict demands of granite/basalt processing. By ensuring ≤5% needle flakes and high cubic-shaped output, these machines are indispensable for modern aggregate production.
