Spring Cone Crusher

• Pure Spring Overload Protection System: The spring cone crusher adopts full mechanical spring safety structure. When uncrushable foreign matter enters the crushing cavity, the spring group automatically releases pressure to lift the movable cone and discharge impurities, effectively protecting the main machine with sensitive and reliable protection performance.
• Ultra-high Operational Stability: Mature decades-old structure design with simple mechanical transmission, no complex hydraulic and intelligent circuit failures. The spring cone crusher can run continuously and stably under harsh dusty and heavy-load working conditions, with extremely low shutdown rate.
• Low Initial Investment Cost: Compared with hydraulic and compound cone crushers, the spring cone crusher has lower equipment price and no high configuration cost. It is very suitable for customers with limited budget and conventional crushing demands.
• Simple Operation & Easy Maintenance: The whole machine has fewer precision components and standardized vulnerable parts. Manual gap adjustment and regular lubrication can meet daily operation requirements. Maintenance difficulty and technical dependence are far lower than hydraulic models.
• Excellent Lamination Crushing Effect: Adopts layered material squeezing crushing technology, reducing flaky particle content. Finished aggregates present uniform cubic shape and reasonable gradation, meeting standard construction and road aggregate quality requirements.
• Strong Environmental Adaptability: Pure mechanical structure is not affected by temperature, voltage and hydraulic oil quality. The spring cone crusher can work normally in high temperature, low temperature and poor-site environments with strong environmental adaptability.
• Long Service Life: High-strength cast steel frame and thickened wear-resistant liners match durable spring components. The whole machine has long service life and low comprehensive replacement cost of accessories.

• Conventional quarry secondary and fine crushing of granite, basalt, river stone and bluestone
• Medium and small-scale mining crushing of iron ore, copper ore and other hard metal minerals
• Standard aggregate production for municipal construction and ordinary road projects
• Fixed crushing station supporting medium and fine crushing equipment
• Construction waste hard concrete material recycling and reprocessing
• Budget-friendly crushing projects with stable and low-maintenance requirements

• Reinforced Cast Steel Frame: Integral thickened cast steel frame with high overall rigidity and strong vibration resistance, avoiding structural deformation during long-term heavy-load operation of the spring cone crusher.
• Precision Eccentric Transmission Mechanism: High-precision bevel gear pair drives the eccentric sleeve to rotate stably, providing stable periodic swing stroke for the movable cone to ensure uniform material crushing effect.
• High Wear-resistant Crushing Liners: Mantle and concave are made of high manganese steel alloy material, with strong compression resistance and abrasion resistance, adapting to long-term crushing of various hard ores and stones.
• Full Spring Safety Protection System: Multiple groups of high-strength compression springs are evenly arranged around the frame, forming an all-round mechanical overload protection structure, the core feature of the spring cone crusher.
• Manual Gap Adjustment Mechanism: Equipped with adjusting ring and locking ring structure, users can manually adjust the discharge gap accurately to switch between medium and fine crushing modes.
• Closed Dust-proof & Lubrication Structure: Adopts closed labyrinth dust-proof design and circulating lubrication system to prevent dust from entering transmission parts and ensure stable operation of core components.
