Spring Cone Crusher

HIGH EFFICIENCY TRAMP IRON PROTECTION

Heavy Duty Cone Crusher Machine for Mining & Quarrying

The Spring Cone Crusher features a compact structure and high production efficiency, widely trusted as premium secondary cone crusher and fine cone crusher equipment in international mineral dressing and aggregate plants. Utilizing a bowl-shaped bearing for advanced precision reserve, this robust stone cone crusher integrates a centralized thin oil lubrication system alongside a novel dry oil/water sealing dust-proof system. It is uniquely engineered to process medium-to-hard minerals and rocks, including river pebbles, granite, basalt, iron ore, limestone, quartz stone, sandstone, copper ore, and gold ore, making it an essential rock crusher machine for high-abrasion mining configurations.

Performance & Structural Features

Why global mining operators choose Hengtai Spring Cone Impactors for hard rock lines.

  • High Efficiency & Large Reduction Ratio: Continuous rotation of the moving cone ensures crushing and discharging alternate seamlessly. Paired with parallel zones of equal gap, it delivers excellent cubical particles with a uniform size distribution.
  • Dual Sealing Protection Matrix: Incorporates dual-mode dry oil and water sealing setups, making it difficult for dust and impurities to enter the body. This guarantees lubrication cleanliness and extends the service life of sliding and thrust ball bearings.
  • Heavy-Duty High-Manganese Castings: The crushing chamber is engineered with premium high-manganese steel (such as Mn18Cr2) liners. Materials undergo intensive compression and shearing between the heavy-duty mantle and concave, delivering uniform wear, minimized power consumption, and extended continuous service life for the entire rock cone crusher.
  • Flexible Cavity Configurations: Available in Standard type (ideal for medium crushing), Medium type (for fine crushing), and Short Head type (perfect for ultra-fine aggregate shaping) to fit distinct plant needs.
  • Reliable Overload Insurance System: Employs a spring safety system to provide robust anti-iron overload protection. Non-crushable metal foreign objects pass safely through the chamber without harming the internal components.
  • Low Maintenance Cost & Quick Service: Simple structural design allows for convenient disassembly, swift cleaning, and easy maintenance, drastically minimizing unexpected operational downtime.

Working Principle

How gyratory pendulum swing forces deliver powerful multi-angle material reduction.

01

Component Structure Base: The PY spring cone crusher mainly consists of the main frame, fixed cone assembly (concave), moving cone assembly (mantle), spring safety mechanisms, bowl-shaped bearing frame, and driving parts. Its auxiliary parts comprise electrical systems, thin oil lubrication, and hydraulic clearing setups.

02

Eccentric Gyratory Motion: During operation, the electric motor drives the large bevel gear at the bottom of the eccentric sleeve through a fluid coupling and small pinion gear. As the eccentric sleeve rotates, it forces the vertical main shaft and crushing cone to make a continuous gyratory pendulum movement.

03

Continuous Crushing Loop: This pendulum swing causes the mantle surface to approach and recede from the concave surface periodically. Rocks entering the cavity are continuously squeezed, bent, and impacted. Crushed materials smaller than the discharge setting fall via gravity through the parallel zone opening.

Frequently Asked Questions (FAQ)

Quick industrial answers to assist buyers with spring cone crusher selection.

Q1: How do standard, medium, and short-head cone crusher cavities differ in performance?

The difference lies in the parallel zone design of the crushing chamber. Standard types feature a shorter parallel zone and wider feed throat, making them ideal for high-volume secondary crushing. Medium and Short Head types have longer, flatter parallel zones, optimizing them for fine and ultra-fine rock reduction to produce concrete aggregates.

Q2: How does the spring mechanism achieve tramp iron protection on a stone cone crusher?

The heavy-duty springs around the upper frame act as an uncrushable safety relief valve. When steel fragments or tramp iron enter the chamber, the spring stack compresses instantly, lifting the supporting ring and upper bowl to widen the discharge gate. This automatically purges the foreign metal block without stopping the motor.

Q3: What are the main benefits of using a thin oil lubrication system in mining cone crushers?

The automated centralized thin oil lubrication system ensures constant oil supply to the eccentric bushing, drive shafts, and thrust bearings. It provides dual benefits of dynamic surface lubrication and active heat dissipation, allowing the heavy cone crusher to run stably for 24-hour continuous operations in harsh ambient conditions.
