Stone cone crushers are widely used in mining, aggregate production, and construction industries for crushing hard and medium-hard materials. They come in different types based on design, application, and crushing principles. Here are the main types:
1. Based on Crushing Principle

# (a) Standard (Coarse) Cone Crusher
– Used for secondary crushing (after jaw crusher).
– Produces coarser output (typically 20–100 mm).
– Suitable for medium to large-sized feed.
– Examples: Symons standard cone crusher.
# (b) Short Head (Fine) Cone Crusher
– Used for tertiary or quaternary crushing.
– Produces finer output (typically 5–20 mm).
– Has a steeper head angle and smaller feed opening.
– Examples: Symons short-head cone crusher.
# (c) Multi-Cylinder Hydraulic Cone Crusher (HP Series)
– Uses multiple hydraulic cylinders for better crushing force.
– Adjustable discharge size with high efficiency.
– Suitable for hard rocks like granite and basalt.
– Examples: Metso HP series, Sandvik CH/CS series.
# (d) Single Cylinder Hydraulic Cone Crusher
– Simpler design with one hydraulic cylinder.
– Good for medium-hard to hard materials.
– Lower cost compared to multi-cylinder models.
– Examples: Nordberg GP series.

2. Based on Mobility
# (a) Stationary Cone Crusher
– Fixed installation in plants or quarries.
– Higher capacity and durability.
# (b) Mobile Cone Crusher
– Mounted on tracks or wheels for portability.
– Used in temporary sites or recycling applications.
– Examples: Lokotrack (Metso), Powerscreen Maxtrak.

3. Based on Drive System
# (a) Electric Motor-Driven Cone Crusher
– Common in stationary plants with reliable power supply.
# (b) Diesel-Hydraulic Cone Crusher
– Used in mobile units where electricity is unavailable.

4. Specialized Types

# (a) Compound Cone Crusher (Symons Type)
– Combines spring and hydraulic systems.
– Cost-effective but less efficient than full hydraulic models.
# (b) Spring Cone Crusher
– Older design with spring-based overload protection.
– Less precise than hydraulic models but cheaper.
