Compact Structure Spring Cone Crusher Machine 35-60TPH for Medium Hard and Hard Ores

Industrial heavy-duty spring cone crusher is a time-tested classic secondary crushing equipment optimized for long-term high-load hard material processing. Different from ordinary crushing machines, it adopts industrial-grade integrated spring overload safety protection structure, which can cope with accidental foreign matter impact in high-load production and fundamentally solve the problem of vulnerable parts damage of hard rock crushing equipment. The whole machine adopts reinforced integrated frame and thickened wear-resistant lining plates, with strong structural rigidity and impact resistance, adapting to 24-hour continuous heavy-duty operation. The standardized 220KW high-power motor provides stable and strong crushing power, ensuring a sustained hourly output of 35-60TPH. With diversified interchangeable crushing cavity configurations, the equipment can freely switch industrial medium crushing and fine crushing modes, with precise adjustable discharge particle size between 13-38mm, fully meeting industrial-grade aggregate fineness standards. Equipped with optional automatic control system and one-year complete warranty service, this heavy-duty spring cone crusher features stable performance, low failure rate and ultra-high durability, becoming the preferred core equipment for medium and small industrial mines, aggregate processing bases and infrastructure engineering projects.

The spring cone crusher drives the eccentric sleeve to rotate through the motor and transmission system, making the movable cone do periodic swinging and eccentric motion around the fixed cone. After hard materials such as granite, basalt and iron ore evenly enter the crushing cavity, they are continuously squeezed, impacted and ground between the movable cone and fixed cone, realizing layered progressive medium and fine crushing. Qualified fine aggregates are discharged downward through the gap at the bottom of the crushing cavity, while unqualified coarse materials stay in the cavity for repeated crushing. The core spring safety protection system acts as an automatic protection barrier during operation: once ultra-hard foreign impurities that cannot be crushed enter the cavity, the spring assembly automatically compresses to increase the discharge gap, discharge the obstructions smoothly, and then reset quickly to restore normal crushing operation. The whole crushing process is stable, safe and controllable, effectively protecting key components from impact damage.

• Professional Spring Overload Protection System Built-in independent spring safety structure realizes automatic compression and reset when encountering foreign matters, effectively preventing equipment impact damage and greatly improving operational safety and service life.
• Flexible Particle Size Adjustment Matched with various interchangeable cavity liners, it supports free switching between medium crushing and fine crushing. The discharge size can be adjusted from 13mm to 38mm to meet diverse aggregate standards.
• Stable & Reliable Production Capacity Equipped with standard 220KW high-efficiency motor, the hourly output stably reaches 35-60TPH, ensuring continuous and efficient material processing for medium and small crushing lines.
• Compact Structure & Low Cost Simplified and reasonable structural design reduces equipment investment cost and floor space, with simple assembly and low energy consumption, bringing high cost-performance ratio for users.
• Easy Daily Maintenance Standardized component layout and detachable wearing parts design make daily inspection, lubrication and replacement work more convenient, reducing later maintenance time and cost.
• Optional Automatic Control System Support customized automatic configuration, realizing intelligent feeding, crushing and discharging monitoring, improving overall production intelligence and operation efficiency.

Widely applicable for medium and fine crushing of medium-hard and hard materials including limestone, granite, basalt, iron ore and river pebble. It is perfectly matched with fixed crushing production lines, suitable for small and medium-sized aggregate yards, mine processing plants, highway construction, municipal engineering and water conservancy project aggregate production.
