What Is a Spring Cone Crusher?
A Spring Cone Crusher is a compression-type crusher that uses the relative movement between the mantle and concave to crush materials inside the crushing chamber.
The spring safety system acts as an overload protection mechanism. When uncrushable material such as iron enters the crushing chamber, the spring system allows the material to pass through the crusher, helping protect the main machine from damage.
According to the STM product brochure, the spring cone crusher is widely used in mining, metallurgy, construction, road construction, chemical and silicate industries. It is designed for crushing various minerals and rocks with medium or higher hardness.
How Does a Spring Cone Crusher Work?
The working process can be summarized as follows:
Feeding → Crushing → Discharge
- Feeding Crushed material from a jaw crusher or other primary crusher enters the cone crusher through the feed opening.
- Compression Crushing The moving crushing cone approaches and moves away from the fixed concave. Material is compressed and crushed inside the crushing chamber.
- Particle Reduction Repeated compression reduces the material to the required size.
- Discharge Once the material reaches the required size, it passes through the discharge opening and exits the crushing chamber.
- Overload Protection If uncrushable metal enters the chamber, the spring safety system provides overload protection and allows the foreign material to pass through.
This design makes the spring cone crusher suitable for continuous crushing applications where reliability and simple operation are important.
Why Choose STM Spring Cone Crusher?
1. Reliable Spring Safety System
The spring safety system provides overload protection when uncrushable materials enter the crushing chamber.
This helps reduce the risk of serious damage to the crusher and supports stable operation.
2. Suitable for Hard Rock Crushing
The spring cone crusher is designed for crushing medium and higher-hardness minerals and rocks.
Typical applications include:
- Granite
- Limestone
- River stone
- Various ores
- Aggregate materials
- Other hard and abrasive rock materials
The exact material suitability depends on the model, crushing cavity and production requirements.
3. Flexible Crushing Cavity Selection
Different crushing cavities can be selected according to the required crushing stage.
Standard Type
The standard cavity is generally used for:
- Coarse crushing
- Medium crushing
- Secondary crushing
Short-Head Type
The short-head cavity is generally used for:
- Medium crushing
- Fine crushing
- Tighter product size requirements
STM’s brochure specifically identifies the standard type for coarse/medium crushing and the short-head type for medium/fine crushing.
4. Convenient Adjustment
The discharge opening can be adjusted according to the required product size and processing conditions.
This makes the crusher easier to integrate into different crushing production lines.
5. Economical Operation
The combination of a relatively simple mechanical structure, reliable protection system and convenient maintenance helps make the spring cone crusher an economical choice for suitable crushing applications.

Spring Cone Crusher Applications
STM Spring Cone Crushers can be incorporated into crushing systems for a variety of industries.
Quarry Crushing
For quarry applications, the spring cone crusher can be used as a secondary or further crushing stage after primary crushing.
Typical materials include:
- Granite
- Limestone
- River stone
- Other quarry rocks
The final configuration should be selected according to feed size, hardness, required capacity and final product size.
Mining and Ore Crushing
Spring cone crushers are widely used in mineral processing applications for crushing various ores.
Possible applications include:
- Metal ore
- Non-metallic mineral
- Hard rock
- Mineral aggregate
For mining projects, the crusher can be combined with feeders, screens, conveyors and primary crushers to create a complete crushing circuit.
Aggregate Production
A spring cone crusher can be used in aggregate production when the material requires secondary or tertiary crushing.
A typical process can be:
Vibrating Feeder → Jaw Crusher → Spring Cone Crusher → Vibrating Screen → Finished Aggregate
Oversized material from the screen can be returned to the cone crusher for further crushing.
Road Construction
The crusher can also be integrated into aggregate production systems for road construction projects.
The appropriate cavity and discharge setting can be selected according to the required aggregate size.
Spring Cone Crusher in a Complete Crushing Plant
A spring cone crusher is normally not used as an isolated machine in a large crushing project.
Instead, it can be integrated with other equipment to create a complete production line.
Typical Crushing Plant
Raw Material—Vibrating Feeder—Jaw Crusher—Spring Cone Crusher—Vibrating Screen—Finished Aggregates
Oversized material can be returned to the cone crusher through a conveyor to form a closed crushing circuit.
STM’s brochure also shows cone crushers being integrated with vibrating screens and conveyors in mobile crushing configurations, including PYB900 and PYB1200.
Spring Cone Crusher vs Jaw Crusher
| Feature | Jaw Crusher | Spring Cone Crusher |
|---|---|---|
| Main crushing stage | Primary crushing | Secondary / further crushing |
| Crushing method | Compression | Compression |
| Typical feed size | Larger | Smaller after primary crushing |
| Product size | Coarser | Finer |
| Hard rock | Yes | Yes |
| Typical role | Initial size reduction | Further size reduction |
In many complete crushing plants, a jaw crusher performs the initial crushing while the spring cone crusher performs the secondary crushing stage.
Spring Cone Crusher vs Hydraulic Cone Crusher
Spring cone crushers and hydraulic cone crushers can both be used for medium and fine crushing, but their structures and protection systems are different.
Spring Cone Crusher
- Mechanical spring overload protection
- Simple and robust structure
- Convenient adjustment
- Economical for suitable applications
- Standard and short-head cavity options
Hydraulic Cone Crusher
- Hydraulic adjustment and protection systems
- More advanced control functions
- Suitable for demanding high-capacity applications
- More complex hydraulic and lubrication systems
STM’s product range also includes CS and multi-cylinder hydraulic cone crushers, allowing customers to select different cone crusher technologies according to the required production process.
How to Choose the Right Spring Cone Crusher?
Choosing a spring cone crusher should be based on several technical factors.
1. Material Hardness
First determine the hardness and abrasiveness of the material.
Harder and more abrasive materials may require different cavity configurations and wear-resistant components.
2. Maximum Feed Size
The maximum feed size should be within the recommended feed range of the selected crusher.
For example:
- PYB900: maximum feed size 115 mm
- PYB1200: maximum feed size 145 mm
- PYB1750: maximum feed size 215 mm
- PYB2200: maximum feed size 300 mm
3. Required Capacity
STM’s brochure lists capacities ranging from approximately 40 t/h for PYB600 to 590–1000 t/h for PYB2200.
The correct model should be selected according to the actual required production rate rather than simply choosing the largest available model.
4. Required Product Size
The required final product size determines the appropriate crushing cavity and discharge setting.
For example:
Standard cavity → Coarse / medium crushing
Short-head cavity → Medium / fine crushing
5. Crushing Plant Configuration
The cone crusher should also be matched with:
- Jaw crusher
- Vibrating feeder
- Vibrating screen
- Belt conveyor
- Dust control equipment
- Other auxiliary equipment
The final equipment configuration should be based on the complete production process.
