In the stone production industry, hard rock has always been a headache. High-hardness rock formations like granite, basalt, and river pebbles not only cause significant wear and tear on equipment, but also directly impact production efficiency and product quality.
Hard rock crushing differs from ordinary limestone or medium-hard rock. Its compressive strength can reach over 250 MPa, placing extremely high demands on equipment wear resistance, crushing force, and process design.
• Rapid equipment wear and frequent component replacements
• Unstable production output, making it difficult to achieve expected targets
• Poor finished product particle shape and a high content of needle-like flakes
• High operating costs and low overall efficiency
Given the characteristics of hard rock, we recommend the classic "jaw crusher + impact crusher" combination, a proven configuration in countless hard rock crushing projects.
When designing a hard stone crushing line, the choice of primary crushing equipment is crucial, determining the overall processing capacity and operational stability of the entire line. The C Series deep-cavity jaw crusher, with its superior crushing performance and reliability, is the ideal primary crushing solution for hard stone crushing lines with an output of 80-100 tons per hour.
• Model: C100
• Feed Inlet Dimensions: 760 x 1060 mm
• Maximum Feed Size: 600 mm
• Features: Utilizing a high-strength frame and high-quality jaw plates, it offers a deep crushing chamber and high processing capacity, making it ideal for primary crushing of hard stone.
2. Secondary and Fine Crushing Stage: PF1315 Impact Crusher
The impact crusher utilizes the impact crushing principle, subjecting the material to repeated impact, friction, and grinding within the crushing chamber. The resulting finished product is typically cubic and full-grained, making it particularly suitable for high-grade construction aggregates and commercial concrete.
• Operational Results:
• Actual Output: 105 tons/hour (stable)
• Finished Product Qualification Rate: >95%
• Blow Bar Service Life: 600-800 hours (granite working conditions)
3. Auxiliary Equipment is also crucial
A complete production line requires the perfect coordination of auxiliary equipment such as vibrating feeders, vibrating screens, belt conveyors, and electronic control systems. We provide a one-stop solution to ensure that all equipment works together for maximum efficiency.
• Tailored Configuration: Optimized jaw + cone/impact crusher combos for materials (hardness, moisture, size) and capacity (50–2,000 t/h).
• Smart Control: PLC automation for remote monitoring and self-adjustment (e.g., cone crusher discharge).
• Comprehensive Support: From planning to maintenance, ensuring long-term operational efficiency.
• Durable Parts & Upkeep: Premium wear parts (e.g., jaw plates, hammers) and proactive maintenance for sustained performance.
