PY Series Cone Crusher
The PY Series Cone Crusher is the standard secondary and tertiary crushing equipment for hard rock and mineral processing operations. Using an eccentrically rotating mantle within a concave bowl liner, the cone crusher compresses material through a gyrating crushing action that is particularly effective for medium-hard to very hard materials. The PY crusher features a spring overload protection system that automatically opens the discharge opening to pass uncrushable tramp metal, preventing machine damage. With adjustable discharge settings and multiple chamber profiles available, the cone crusher produces aggregate and grinding mill feed from 3mm to 60mm with excellent particle shape and uniform distribution.
Working Principle
The cone crusher consists of a fixed concave bowl liner and an eccentrically gyrating mantle. The mantle gyrates within the bowl, creating compressive crushing action as it approaches and retreats from the bowl liner. Material enters the upper crushing chamber and is compressed between mantle and bowl liner. As the mantle gyrates, crushed material moves downward and exits through the discharge opening. The spring system provides overload protection by allowing the mantle to drop away from the bowl when uncrushable material enters.
The grinding process is precisely controlled by the integrated classification system, which separates qualified fine powder from coarse particles. Coarse particles fall back to the grinding chamber for regrinding, while fine powder is conveyed by airflow to the cyclone collector and then to the finished product silo. This closed-circuit design ensures consistent product quality and high grinding efficiency.
Key Features & Advantages
Hard Rock Crushing Specialist

Performance & Efficiency
The PY Series Cone Crusher is designed for maximum grinding efficiency and energy savings. The optimized grinding chamber geometry, combined with high-precision classification, ensures that energy is used effectively for particle size reduction rather than wasted on over-grinding or heat generation. Compared to conventional milling systems, our equipment typically achieves 20-30% lower power consumption per ton of finished powder.
Key performance metrics include stable fineness control with deviation less than 5%, low noise levels below 75 dB at 1 meter distance, and dust emissions below 20 mg/m3 when equipped with our pulse bag filter system. These performance characteristics make our equipment suitable for even the most demanding industrial environments and stringent environmental regulations.
Installation & Commissioning
Proper installation is critical for optimal equipment performance and longevity. Our experienced engineers provide on-site installation and commissioning services, including equipment positioning, alignment, electrical connection, piping installation, and system integration. The typical installation timeline ranges from 15 to 45 days depending on equipment model and production line complexity.
During commissioning, we conduct comprehensive performance tests including no-load test, load test, and production trial runs. We verify all performance parameters meet design specifications, calibrate control systems, train your operators on proper operation and maintenance procedures, and deliver a complete commissioning report with all test data.
Frequently Asked Questions
Coarse chambers have wider feed opening and larger discharge for primary/secondary crushing. Medium chambers for general secondary crushing. Fine chambers have narrower feed for tertiary crushing with smaller output. The chamber profile is selected based on feed size and desired output.
When uncrushable material (tramp metal) enters, the upward force exceeds spring tension, causing the bowl to lift and the discharge opening to widen. The tramp material passes through, then springs push the bowl back to its original setting. This prevents mantle, bowl liner, or frame damage.
For medium-hard granite, expect 2-4 months. For very hard basalt, 1-3 months. For limestone, 6-12 months. Liner life depends on material hardness, feed size, and operating hours.
