Schematic Diagram of the Limestone Crushing Production Line Process
In limestone crushing production lines with a capacity of 80-100 tons per hour, the CS75 Symons cone crusher, with its layered crushing principle and high-manganese steel wear parts, has become the cost-effective choice for the medium crushing stage. This article details its process configuration, performance parameters, and four core advantages for limestone processing.
1. Typical 80-100TPH Limestone Production Line Configuration
For limestone (medium hardness, low abrasiveness) processing, we recommend the classic two-stage crushing process of "jaw crusher + cone crusher" to achieve optimal particle shape control and operating cost balance.

CS75 Cone Crusher
• Primary Crushing: PE500x750 or PE600x900 jaw crusher (processing raw materials ≤500mm)
• Intermediate Buffer: An intermediate stockpile is provided to ensure continuous feeding for secondary crushing.
• Secondary Medium Crushing: CS75 Symons cone crusher (standard model for medium crushing).
• Screening and Grading: 3YK1860 circular vibrating screen (producing finished products of 0-5mm, 5-10mm, 10-20mm, 20-30mm, etc.).
• Conveying System: Total installed power controlled at approximately 150-180kW.
2. Four Major Technical Advantages of the CS75 Cone Crusher on Limestone Production Lines
① Layered Crushing, Particle Shape is Not Just "Round"
The CS75 adopts a typical layered crushing principle, where materials are subjected to all-around compression within the crushing chamber. Compared to impact crushers, it produces aggregates with lower needle-like and flaky content and more continuous gradation, fully meeting the stringent requirements of high-performance concrete for limestone aggregates.
② High-Durability Design Optimized for Limestone Characteristics
Although limestone is not particularly hard, continuous long-term operation still inevitably causes wear on the crusher liners. The CS75 utilizes high-manganese steel for both its bowl liner and mantle, paired with an optimized crushing frequency. Under a load of 80–100 t/h, the service life of its liners is extended by more than 15% compared to similar equipment.
③ Constant Setting Size (CSS) Ensures High Product Yield
The CS75 features a highly responsive chamber clearing and adjustment system. Even during continuous operation, the discharge setting maintains exceptional stability, ensuring that the proportion of the "golden size" fraction (10–20 mm) in the finished product consistently remains above 45%.
④ Low Maintenance Costs, High Uptime
The CS75 boasts an extremely mature structural design and employs a dry-grease sealing system. In dusty limestone crushing environments, its sealing performance far surpasses that of older-style spring cone crushers, thereby reducing lubricant contamination and bearing wear, and cutting annual maintenance downtime by approximately 72 hours.

4. Frequently Asked Questions (FAQ)
Q: Why choose the CS75 cone crusher over an impact crusher for a 100 t/h production line?
A: Impact crushers are suitable for processing extremely soft materials; however, when producing high-quality construction aggregates, they suffer from rapid wear on consumable parts and generate a high proportion of fines (powder). The CS75 offers lower operating costs, and—when processing medium-hardness materials such as limestone—its superior durability translates directly into higher total annual production output.
Q: Is the CS75 capable of producing manufactured sand in the 0–5 mm size range?
A: The standard configuration of the CS75 is primarily designed for secondary crushing (yielding material in the 10–30 mm range). If you require high-volume production of 0–5 mm manufactured sand, we recommend adding a VSI vertical shaft impact crusher or opting for the "Short Head" configuration of the CS75 to handle the fine crushing stage.
5. Baichy Summary
"In the 80–100 t/h niche market, the CS75 is virtually an 'all-around champion.' It does not chase extreme, ultra-high production capacities; rather, it prioritizes a stable, low cost per ton. For small to medium-sized limestone quarries, choosing the CS75 means securing peace of mind for the next five years."
