What is a Spring Cone Crusher?

A spring cone crusher is a compression‐type crushing machine that uses a mantle gyrating inside a concave bowl to crush materials by squeezing, shearing, and bending. The “spring” in its name refers to the safety device built into the machine—when non‐crushable material enters the chamber, the springs allow the material to pass through and protect the crusher from damage.

As with a Symons cone crusher, the design traditionally uses an eccentric sleeve and moving cone to create a crushing motion, and a fixed bowl (concave) to form the crushing chamber. Over time, variations have emerged including hydraulic adjustment, double‐spring systems, mobile chassis, crawler tracks, etc.

Key Components & Working Principle

Typically, a spring cone crusher includes the following core parts: frame, hollow eccentric shaft, transmission device (belt/pulley or motor direct drive), bowl‐shaped bearing, moving cone, fixed cone (shell), springs, and lubrication/drive system. The crusher works by:

Feeding material into the crushing chamber (between fixed and moving cone).
Motor drives the eccentric sleeve, which causes the moving cone to swing and compress the material.
The gap between the moving and fixed cone changes as the moving cone gyrates, creating extrusion, shearing, and impact forces to crush the material.
Crushed material discharges through the bottom of the chamber when the gap is met.
The springs act as overload protection—should uncrushable material enter, the springs compress and allow passage, preventing damage.

Why Choose a Spring Cone Crusher?

There are several reasons why many operations favour the spring cone crusher:

High crushing ratio and production efficiency: The spring cone crusher is used for medium and fine crushing operations and can deliver high output with consistent performance.
Versatility in material handling: It can handle a wide range of materials – from limestone and marble to granite and basalt (hard rock). In other words, a “hard stone cone crusher” is well within its operation envelope.
Uniform product size: Thanks to the crushing action (compression, shearing, bending) and cavity design, the final product often has a more uniform size and better cubical shape than some alternatives.
Easy maintenance & safety features: Features like dry‐oil sealing, spring safety system (overload protection), adjustable discharge setting, and reliable lubrication help minimize downtime and maintenance costs.
Multiple configurations: From fixed plant installations (“cone crusher plant”) to mobile versions (“mobile cone crusher”, “crawler mobile cone crusher”), the spring cone crusher can be configured to suit many production scenarios.

Applications – Where Does It Fit?

The spring cone crusher is used widely across industries:

Mining: For crushing ore (iron, copper, etc.).
Aggregates & Quarrying: Crushing rock and stone (granite, basalt, river stone) and creating finished aggregates.
Construction & Infrastructure: Road, bridge, railway construction where stone size and shape matter.
Crushing plant setups: As a secondary, tertiary, or quaternary crusher in a “cone crusher plant” setup, especially when feeding from a primary crusher or screening system.
Mobile & remote sites: “Mobile cone crusher” and “crawler mobile cone crusher” setups allow flexibility, rapid deployment, and relocation.

In scenarios involving hard stone (granite, basalt), you’ll want a machine that is explicitly designed for such conditions—thicker liners, stronger frames, appropriate cavity types (coarse, medium, fine). The spring cone crusher fits well as a hard stone cone crusher option.

“Cone Crusher for Sale” and “Cone Crusher Price” Considerations

When you search for a cone crusher for sale, and look at cone crusher price, there are several factors you should consider:

Price Range

The price of a cone crusher depends on size, capacity, configuration (fixed vs mobile), features (hydraulic vs spring), brand reputation, and customization. While exact pricing varies widely, listings for spring cone crushers show ranges in the tens of thousands USD (for smaller units) and upward for larger capacity models. For example, one listing for a spring cone crusher shows a price of USD 41,000-43,000.

Factors Influencing Price

Size & capacity: Larger feed size and higher capacity models cost more.
Brand/manufacturer: Reputed manufacturers often command higher price due to quality, service, warranty.
Feature set: Mobile vs fixed, crawler track vs wheeled, hydraulic adjustment vs manual, automation.
Wear parts & material: Harder material capability (granite, basalt) requires stronger wear parts and robust structure – leads to higher cost.
After-sales support: Spare parts availability, local support, service network.
Location, transport & installation: Shipping, customs, installation, commissioning add to total cost.

Tips Before Purchase

Clarify the required capacity (t/h) and feed size of your material.
Ensure the machine is rated for hard stone if you handle granite or basalt.
Confirm the warranty, spare parts availability, and support from the manufacturer.
Ask for total cost of ownership (installation, wear parts, downtime).
Compare mobile vs fixed: a mobile or crawler mobile cone crusher may cost more upfront but may save on relocation and setup costs.
Check for adjustable discharge opening, safety system (spring overload protection), sealing system (dry oil or water) – these influence maintenance cost.

Mobile Cone Crusher & Crawler Mobile Cone Crusher

A modern trend in the crushing business is the mobile cone crusher and crawler mobile cone crusher. These offer significant advantages in flexibility, relocation, and reduced infrastructure.

Advantages

Mobility: You can move the crusher closer to the feed source, reducing hauling cost.
Versatility: Mobile plants can be set up, relocated, and modified for different jobs or sites.
Reduced infrastructure: Less fixed foundation or long conveyors needed.
Faster deployment: Often faster to install and commission than fixed plants.

Use-cases

Construction and demolition sites.
Remote or temporary quarry operations.
Where flexibility and rapid changeover are required.
Hard stone operations where you need to move equipment as face advances.

Considerations

Mobile machines may cost more upfront (transport, chassis, hydraulics).
Maintenance access sometimes more constrained than fixed units.
Power supply (whether electrical or diesel) must be compatible.
For hardstone operations (granite/basalt) ensure the mobile cone crusher is rated properly (wear parts, structure).

If you’re looking at a mobile cone crusher for sale, evaluate the same price and specification factors as fixed units but also consider logistics and mobility costs.

Design & Features: What to Look For in a Hard Stone Cone Crusher

Crushing hard stone (granite, basalt, quartzite) places high demands on your cone crusher. Here are features/design points you should pay attention to:

Strong frame & heavy structure: To resist high compressive forces.
High quality wear parts: Mantle and concave made from high Mn or Cr alloys with good wear resistance.
Spring safety & overload protection: To avoid damage when uncrushable material enters the chamber. The spring cone crusher’s traditional advantage.
Adjustable discharge opening (CSS / OSS settings): Critical to control product size and optimise throughput.
Sealing & lubrication systems: Dry oil seal or water seal to protect bearings/lubrication from dust and debris
Multiple cavity types: Allow you to choose coarse, medium, fine crushing chamber depending on feed size and target output. (B, Z, D types)
